Exelon Corporation and Subsidiary Companies Management's Discussion and Analysis
of Financial Condition and Results of Operations


MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATIONS

(Dollars in millions, unless otherwise noted)

General Business

         On  October  20,  2000,  Exelon  Corporation  (Exelon or we) became the
parent  corporation  for PECO  Energy  Company  (PECO) and  Commonwealth  Edison
Company (ComEd) as a result of a merger among PECO, Unicom Corporation (Unicom),
the  former  parent  company  of ComEd,  and  Exelon  (Merger).  The  Merger was
accounted for using the purchase method of accounting with PECO as the acquiring
company.  Accordingly,  our  results of  operations  for 2000  consist of PECO's
results of operations for 2000 and Unicom's  results of operations after October
20, 2000.

         During  January  2001,  we  undertook a  restructuring  to separate our
generation and other  competitive  businesses from our regulated energy delivery
business at ComEd and PECO. As part of the restructuring, the generation-related
operations  and  assets and  liabilities  of ComEd  were  transferred  to Exelon
Generation Company,  LLC (Generation).  Also, as part of the restructuring,  the
non-regulated   operations   and  related   assets  and   liabilities  of  PECO,
representing   PECO's  generation  and  enterprises   business  segments,   were
transferred to Generation and Exelon  Enterprises  Company,  LLC  (Enterprises),
respectively.  Additionally,  certain  operations and assets and  liabilities of
ComEd and PECO were  transferred to Exelon Business  Services Company (BSC). BSC
provides  Exelon  and  its  subsidiaries  financial,   human  resource,   legal,
information technology, supply management and corporate governance services.

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

     o    Energy  Delivery,  whose  businesses  include  the  regulated  sale of
          electricity and  distribution  and  transmission  services by ComEd in
          northern  Illinois and 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 the  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 competitive retail energy sales, energy and
          infrastructure   services,   communications   and  other   investments
          (weighted  towards  the  communications,  energy  services  and retail
          services industries).

See Note 20 of the  Notes  to  Consolidated  Financial  Statements  for  further
segment information.



                                        2


Goals and Strategies
         Our vision is to build  exceptional  value - by  becoming  the best and
most consistently  profitable  electricity and gas company in the United States.
To implement our vision, we must

         Live up to our commitments

          o    Keep the lights on.
          o    Perform safely - especially in nuclear operations.
          o    Constantly improve our environmental performance.
          o    Act  honorably  and treat  everyone  with  respect,  decency  and
               integrity.
          o    Continue  building a high  performance  culture that reflects the
               diversity of our communities.
          o    Report our  results,  opportunities  and  problems  honestly  and
               reliably.

         Perform at world-class levels

          o    Relentlessly pursue greater productivity, quality and innovation.
          o    Understand  the  relationships  among our businesses and optimize
               the whole.
          o    Promote and implement policies that build effective markets.
          o    Adapt  rapidly  to  changing  markets,  politics,  economics  and
               technology to meet our customers' needs.
          o    Maximize   the  earnings  and  cash  flow  from  our  assets  and
               businesses and sell those that do not meet our goals.

         Invest in our consolidating industry

          o    Develop  strategies  based on learning  from past  successes  and
               failures.
          o    Implement  systems  and best  practices  that can be  applied  to
               future acquisitions.
          o    Prioritize  acquisition  opportunities  based on  synergies  from
               scale,  scope,  generation  and  delivery  integration,  and  our
               ability to profitably  satisfy provider of last resort (POLR) and
               other regulatory obligations.
          o    Make  acquisitions  that will best employ our limited  investment
               resources to produce the most  consistent  cash flow and earnings
               accretion.
          o    Return  earnings  to  shareholders  when  higher  returns are not
               available from acquisition opportunities.

         The first component of our strategy is to "live up to our commitments."
As such,  we will  continue to make  investments  in our  businesses  to provide
reliable  services  at fair  prices.  The second  component  of our vision is to
"perform  at world  class  levels,"  which  includes  our plan to develop a more
fundamental  and durable  productivity  improvement  program to expand on 2002's
Cost Management  Initiative.  Our process, The Exelon Way, is designed to create
value  and  strengthen  our   competitive   position  by  improving   processes,
productivity  and cash flow. Our third major corporate goal is to "invest in our
consolidating  industry." To further our strategy, each of the business segments
has formulated its own plans to achieve our corporate goals.

         Energy  Delivery.  Energy  Delivery  focuses on providing  reliable and
affordable  services to customers.  ComEd and PECO continue to make improvements
to their  delivery  systems to minimize  the  frequency  and duration of service
interruptions,  while working more  efficiently to lower their costs. We believe
that ComEd and PECO will continue to provide a significant  and steady source of
earnings and cash flows over the next several years.



                                        3


         Generation.  Generation  is focused on providing  low cost and reliable
power  through  a  generation   portfolio  with  fuel  and  dispatch  diversity.
Generation's  direction  is to continue to increase  fleet output and to improve
fleet  efficiency while sustaining  operational  safety.  Power Team is the unit
within  Generation  that  manages the output of  Generation's  assets and energy
sales to reduce the  volatility  of  Generation's  earnings  and cash flows.  We
believe that Generation will provide a steady source of earnings through its low
cost operations and will take advantage of higher wholesale prices when they can
be realized.

         Enterprises.  Enterprises is focused on operating its investments  with
the goal of maximizing its earnings and cash flow.  Enterprises is not currently
contemplating  any  acquisitions.   Enterprises  expects  to  divest  itself  of
businesses that are not consistent with our strategic  direction.  This does not
necessarily  mean that an  immediate  exit will be  arranged,  but rather we may
retain  businesses for a period of time if we believe that this course of action
will strengthen their value.

Business Outlook and the Challenges in Managing Our Business

         We face a number of  challenges in achieving our vision and keeping our
commitments  to our  customers  and our  investors;  however,  there  are  three
principal  areas  on  which  we  focus  our  attention.   First,  our  financial
performance is significantly affected by the availability and utilization of our
generation  facilities.   As  the  largest  U.S.  nuclear  generator,   we  face
operational  and regulatory  risks that, if not managed  diligently,  could have
significant adverse consequences. Second, our results of operations are directly
affected by wholesale energy prices.  Energy prices are driven by demand factors
such as weather and economic  conditions  in our service  territories.  They are
also driven by supply  factors and the regions where we operate  currently  have
excess  capacity.  Over the last several years,  wholesale prices of electricity
have  generally  been low. The  possibility  of continued low wholesale  prices,
coupled with a continued economic recessionary trend, could adversely affect our
business.  Finally,  our  business may be  significantly  impacted by the end of
ComEd's regulatory transition period in 2006. By existing law, after 2006, ComEd
will not collect competitive  transition charges (CTCs) from customers who elect
to receive generation  services from alternative energy suppliers  including the
ComEd Power  Purchase  Option  (PPO).  Additionally,  the current  bundled  rate
structure  may be reset in a regulatory  proceeding.  It is difficult to predict
the outcome of a potential regulatory proceeding to establish rates for 2007 and
thereafter,  nor is it  possible  to  predict  what  changes  may  occur  to the
restructuring law in Illinois;  however,  we are undertaking  various efforts to
mitigate the 2007 challenge.

         These and other  challenges  affecting  our  businesses  are  described
below.  There are  several  factors,  such as  weather,  economic  activity  and
regulatory  actions that affect Energy  Delivery,  Generation and Enterprises in
different  ways.  Also,  there are several factors that affect our business as a
whole,  such as environmental  compliance and the ability to access capital on a
cost-effective basis.

Energy Delivery

         We must comply with numerous  regulatory  requirements  in managing our
         Energy Delivery business,  which affect our costs and responsiveness to
         changing events and opportunities.

         Our Energy Delivery  business is subject to regulation at the state and
         Federal levels.  ComEd is regulated by the Illinois Commerce Commission
         (ICC)  and  PECO  is  regulated  by  the  Pennsylvania  Public  Utility
         Commission (PUC). These state commissions regulate the rates, terms and
         conditions of service;  various  business  practices and  transactions;
         financing;  and transactions  between the utilities and our affiliates.
         Both  ComEd and PECO are also  subject  to  regulation  by the  Federal
         Energy Regulatory Commission (FERC), which regulates their transmission
         rates,  certain other aspects of their  businesses  and, for PECO,  gas
         pipelines.  The

                                        4



         regulations  adopted by these  state and  Federal  agencies  affect the
         manner in which we do  business,  our  ability to  undertake  specified
         actions and the costs of our operations.

         We are involved in a number of regulatory  proceedings as a part of the
         process  of  establishing  the terms and  rates for  Energy  Delivery's
         services.

         These  regulatory   proceedings  typically  involve  multiple  parties,
         including  governmental  bodies,  consumer  advocacy groups and various
         consumers  of  energy,  who have  differing  concerns  but who have the
         common  objective of limiting  rate  increases.  The  proceedings  also
         involve  various  contested  issues  of law and fact and have a bearing
         upon the recovery of Energy  Delivery's costs through  regulated rates.
         During  the course of the  proceedings,  we look for  opportunities  to
         resolve  contested  issues in a manner that grant some certainty to all
         parties to the proceedings as to rates and energy costs.

               o    ComEd Delivery Services Rate Case

                  ComEd  is   authorized   to  charge   customers  who  purchase
                  electricity  from an  alternative  supplier for the use of its
                  distribution   system  to  deliver  that  electricity.   These
                  delivery service rates are set through  proceedings before the
                  ICC based  upon,  among  other  things,  the  operating  costs
                  associated  with ComEd's  distribution  system and the capital
                  investment that ComEd has made in its distribution  system. In
                  April 2002,  the ICC issued an interim order that set delivery
                  rates for ComEd's residential customers. The interim order was
                  subject  to  an  audit  of  test  year  (2000)   expenditures,
                  including  capital  expenditures.  In  October  2002,  the ICC
                  received the report on the audit of the test year expenditures
                  by a consulting  firm engaged by the ICC to perform the audit.
                  The   consulting   firm   recommended    certain    additional
                  disallowances to test year  expenditures and rate base levels.
                  ComEd does not expect any change in delivery  service rates to
                  have a  significant  impact on results of  operations in 2003.
                  However, the estimated potential investment write-off,  before
                  income taxes, could be up to approximately $100 million if the
                  ICC ultimately  determines that all or some portion of ComEd's
                  distribution plant is not recoverable  through rates. In 2002,
                  ComEd recorded a charge to earnings,  before income taxes,  of
                  $12  million   representing  the  estimated  minimum  probable
                  exposure.  ComEd is in  negotiations  with several  parties to
                  resolve the delivery service case.

         We must maintain the availability and reliability of Energy  Delivery's
         delivery systems to meet customer expectations.

         Each  year  increases  in both  customers  and the  demand  for  energy
         requires  expansion and  reinforcement  of delivery systems to increase
         capacity  and  maintain  reliability.  Failures  of  the  equipment  or
         facilities used in those delivery systems could  potentially  interrupt
         energy  delivery  services and related  revenues,  and increase  repair
         expenses and capital expenditures.  Such failures,  including prolonged
         or repeated failures,  also could affect customer  satisfaction and may
         increase  regulatory  oversight  and the level of our  maintenance  and
         capital  expenditures.  In addition,  under  Illinois law, ComEd can be
         required  to pay  damages  to its  customers  in the event of  extended
         outages affecting large numbers of its customers.

         We must  manage  Energy  Delivery's  costs  due to the rate and  equity
         return limitations imposed on Energy Delivery's revenues.

         Rate  freezes  and caps in  effect at ComEd  and PECO  currently  limit
         Energy Delivery's  ability to recover increased  expenses and the costs
         of investments in new transmission and  distribution



                                        5


         facilities.  As a result,  our future results of operations will depend
         on the  ability of ComEd and PECO to deliver  electricity  and,  in the
         case of PECO,  natural gas, in a cost-efficient  manner, and to realize
         cost  savings  to  offset  increased  infrastructure   investments  and
         inflation.

               o    Rate limitations

                  ComEd is subject to a  legislatively  mandated  rate freeze on
                  bundled retail rates that will remain  effective until January
                  1, 2007.  PECO is subject to  agreed-upon  rate  reductions of
                  $200 million,  in aggregate,  for the period 2002 through 2005
                  and  caps  (subject  to  limited  exceptions  for  significant
                  increases   in  Federal  or  state   income   taxes  or  other
                  significant  changes  in law or  regulation  that do not allow
                  PECO to earn a fair rate of  return) on its  transmission  and
                  distribution  rates  through  December 31, 2006 as a result of
                  settlements previously reached with the PUC.

               o    Equity return limitation

                  ComEd is subject to a legislatively mandated cap on its return
                  on common equity  through the end of 2006. The cap is based on
                  a two-year  average of the U.S.  Treasury  long-term rates (25
                  years and above)  plus  8.5%,  and is  compared  to a two-year
                  average  return on  ComEd's  common  equity.  The  legislation
                  requires  customer  refunds  equal to  one-half  of any excess
                  earnings above the cap. ComEd is allowed to include regulatory
                  asset  amortization in the calculation of earnings.  ComEd has
                  not  triggered the earnings  provision and currently  does not
                  expect to trigger the earnings sharing  provision in the years
                  2003 through 2006.

         Energy Delivery has and will lose energy  customers to other generation
         service  providers,  although it continues to provide delivery services
         and may have an  obligation  to  provide  generation  service  to those
         customers.

               o    The  revenues  of our  Energy  Delivery  business  will vary
                    because of customer choice of generation suppliers

                  As a result  of  restructuring  initiatives  in  Illinois  and
                  Pennsylvania,   all  of  Energy   Delivery's  retail  electric
                  customers can choose to purchase their generation  supply from
                  alternative   suppliers.   If   customers  do  not  choose  an
                  alternative  generation supplier or take service under ComEd's
                  PPO, ComEd and PECO are each currently  generally obligated to
                  provide  generation and delivery service to customers in their
                  service  territories  at fixed  rates,  or in some  instances,
                  market-derived  rates.  In addition,  customers  who choose an
                  alternative  generation  supplier may later return to ComEd or
                  PECO,  provided,  however,  that under  Illinois  law  ComEd's
                  obligation to provide  generation may be eliminated  over time
                  if the ICC finds that competitive supply options are available
                  to  certain  classes  of  customers.  ComEd  and  PECO  remain
                  obligated to provide  transmission and distribution service to
                  all customers regardless of their generation supplier.  To the
                  extent that customers  leave  traditional  bundled tariffs and
                  select a  different  generation  provider,  Energy  Delivery's
                  revenues are likely to decline.

                  At December 31, 2002, based on sales of energy,  approximately
                  27% of ComEd's small  commercial and industrial (C&I) load and
                  61% of its  large C&I load were  purchasing  their  generation
                  service from an alternative  generation supplier or had chosen
                  ComEd's  PPO,  a  market-based  price  for  energy.  There are
                  currently  no   certified   alternative   suppliers   for  the
                  residential  market in ComEd's  service  territory.  Also,  at
                  December 31,



                                        6


                  2002,  approximately  10% of PECO's small C&I load,  7% of its
                  large C&I load and 21% of its residential load were purchasing
                  their   generation   service  from  an  alternative   electric
                  generation supplier.

                  PECO's Electric  Restructuring  Settlement  established market
                  share   thresholds   (MST)  for   residential  and  commercial
                  customers  such that if, on  January  1,  2003,  50% of PECO's
                  residential  and commercial  customers (by number of customers
                  for residential and small commercial classes,  and by load for
                  large commercial classes) are not obtaining generation service
                  from  alternative  generation  suppliers,   then  non-shopping
                  customers,  up to the MSTs level, will be randomly assigned to
                  alternative generation suppliers.  The assigned customers have
                  the  right,  at any  time,  to  return to PECO or to switch to
                  another supplier.

                  The  number  of  customers  choosing  alternative   generation
                  suppliers depends in part on the prices being offered by those
                  suppliers relative to the fixed prices that ComEd and PECO are
                  authorized to charge by their state regulatory commissions. As
                  a  result  of the  right  of  customer  choice  of  generation
                  suppliers,  we anticipate  that our revenues and gross margins
                  could vary.

              Energy Delivery  continues to serve as the provider of last resort
              for energy for all customers in its service territories.

              ComEd and PECO are required to make available  generation  service
              to all retail  customers in their service  territories,  including
              customers  that have taken energy from an  alternative  generation
              supplier. ComEd and PECO customers can "switch," that is, they can
              choose an  alternative  generation  supplier and then return to us
              and then go back to an  alternative  supplier,  and so on,  within
              limits. Because customers can switch, planning for Energy Delivery
              has  a  higher  level  of  uncertainty  than  that   traditionally
              experienced  due to weather and the economy.  In order to mitigate
              this risk  with  regard to our  large  commercial  and  industrial
              customers, on July 19, 2002, ComEd filed a request with the ICC to
              revise its POLR  obligation  in Illinois to be the back-up  energy
              supplier to certain  businesses.  ComEd is seeking permission from
              the ICC to limit the  availability by June 2006 of Rate 6L for 370
              of  its  largest  energy  customers.   These  are  commercial  and
              industrial  customers,  including heavy industrial  plants,  large
              office  buildings,  government  facilities  and a variety of other
              businesses  with demands of at least three  megawatts  (MWs).  Our
              request  affects a total of  approximately  2,500 MWs. On November
              14, 2002, the ICC allowed our request to go into effect as of June
              2003. Energy Delivery has no obligation to purchase power reserves
              to cover the load served by others.  Presently, we manage the POLR
              obligation  through full  requirements  contracts with Generation,
              under  which   Generation   supplies   ComEd's  and  PECO's  power
              requirements.  Because  of the  ability  of  customers  to  switch
              generation suppliers, there is uncertainty regarding the amount of
              Energy  Delivery  load that  Generation  must  prepare  for.  This
              uncertainty  increases  Generation's  costs.  As a result,  and in
              connection  with our July 2002 ICC request,  we are discussing the
              POLR obligation issue with a number of parties including those who
              were parties to our rate request.

         Energy Delivery's long-term power purchase agreements provide a partial
         hedge to its customers' demand.

         Because the bundled  rates Energy  Delivery  charges its  customers are
         frozen or capped for several  years,  as  mentioned  previously  in the
         "Rate limitations" section, its ability to recover increased costs with
         increases in rates charged to these customers is limited. Therefore, to
         effectively


                                        7


         manage its obligation to provide power to meet its  customers'  demand,
         Energy Delivery has established power supply agreements with Generation
         that reduce  exposure to the  volatility of market prices through 2006.
         Market  prices  relative  to  Energy  Delivery's  bundled  rates  still
         influence switching behavior among retail customers.

         Our  business  may be  significantly  impacted  by the end of the ComEd
         regulatory  transition period in 2006, and to a lesser extent,  the end
         of the PECO regulatory transition period in 2010.

         Illinois electric  utilities are allowed to collect CTCs from customers
         who choose an alternative  supplier of electric  generation  service or
         choose  a  utility's  PPO.  CTCs  were  intended  to  assist   electric
         utilities,  such as ComEd, in recovering  stranded costs that might not
         otherwise be recoverable in a fully competitive  market. The CTC charge
         represents the difference  between the  competitive  price of delivered
         energy (the sum of  generation  service at  competitive  prices and the
         regulated  price of energy  delivery) and recoveries  under  historical
         bundled  rates,  reduced by a  mitigation  factor.  The CTC charges are
         updated  annually.  Over  time,  to  facilitate  the  transition  to  a
         competitive  market, the mitigation factor increases,  thereby reducing
         the CTC charge. Under current law, ComEd will no longer collect CTCs at
         the end of 2006.

         In 2001,  ComEd  collected $110 million of CTC revenue,  while in 2002,
         CTC revenue  collected  increased  to $306 million due to the change in
         the competitive price of delivered electricity,  primarily due to lower
         wholesale  prices  and  more  customers  choosing   alternative  energy
         suppliers or the ComEd PPO. Based on increasing  mitigation factors and
         our  assumptions  about the competitive  price of delivered  energy and
         customers' choice of electric  suppliers,  we estimate that CTC revenue
         will be  approximately  $250 to  $300  million  annually  by  2006.  In
         addition, the CTC is dependent on the ICC's determination of the market
         price of electricity.  In a proceeding  before the ICC,  various market
         participants, including alternative providers and large customers, have
         proposed  modifications  to the method for determining the market price
         that, if accepted, could have the effect of reducing the CTC. Under the
         current restructuring statute, in 2007 this revenue will likely drop to
         zero.  Through  2006,  ComEd will  continue  to have a bundled  service
         obligation, particularly to residential and small commercial customers.
         ComEd's  current  bundled  service  is  generally   provided  under  an
         all-inclusive  rate that does not  separately  break  out  charges  for
         energy generation  service and energy delivery  service,  but charges a
         single  set of  prices.  Much like the CTC  collections,  this  revenue
         stream is authorized by the legislature  through the transition period.
         After the transition  ends in 2006,  ComEd's bundled rates may be reset
         through a regulatory approval process, which may include traditional or
         innovative pricing, including performance-based incentives to ComEd.

         During informal workshops sponsored by a member of the Illinois General
         Assembly,  various  market  participants  and  interested  parties made
         proposals which, if adopted, could have the effect of reducing the CTC.

         In order to  address  post-transition  uncertainty,  we are  constantly
         working  with  Illinois  state and  business  community  leadership  to
         facilitate the  development of a competitive  electricity  market while
         providing system reliability. This is particularly important as ComEd's
         costs  to  provide   electricity  to  bundled   residential  and  small
         commercial  customers are capped by law at 110% of market.  Transparent
         and liquid markets will help to minimize  litigation  over  electricity
         prices and provide  consumers  assurance of equitable  pricing.  At the
         same time, we are  attempting  to establish a regulatory  framework for
         the post-2006 timeframe.  To offset CTC revenue loss after 2006, we are
         pursuing measures that would provide greater productivity,  quality and
         innovation in our work practices across Exelon.


                                        8


         Our  ability to make  successful  acquisition(s)  and the  recovery  of
         wholesale  power  prices  over the next  several  years will affect our
         ability  to  successfully  manage  this  situation.  Currently,  it  is
         difficult to predict the outcome of a potential  regulatory  proceeding
         to establish rates after 2006. We believe that no one factor will solve
         these  challenges,  but that a combination of the components  currently
         being  worked on,  together  with other things that we will do over the
         next four years, will address these challenges.

         In Pennsylvania,  as a mechanism for utilities to recover their allowed
         stranded costs, the Pennsylvania Electricity Generation Customer Choice
         and Competition Act  (Competition  Act) provides for the imposition and
         collection  of  non-bypassable  CTCs  on  customers'  bills.  CTCs  are
         assessed  to and  collected  from all  retail  customers  who have been
         assigned  stranded  cost   responsibility  and  access  the  utilities'
         transmission and distribution  systems. As the CTCs are based on access
         to the utility's  transmission  and distribution  system,  they will be
         assessed regardless of whether such customer purchases electricity from
         the  utility  or  an  alternative  electric  generation  supplier.  The
         Competition Act provides,  however, that the utility's right to collect
         CTCs  is  contingent  on  the   continued   operation,   at  reasonable
         availability  levels,  of the assets for which the stranded  costs were
         awarded,  except where continued  operation is no longer cost efficient
         because of the transition to a competitive market.

         PECO has been  authorized by the PUC to recover  stranded costs of $5.3
         billion ($4.6 billion of unamortized costs at December 31, 2002) over a
         twelve-year  period  ending  December  31,  2010,  with a return on the
         unamortized  balance of 10.75%.  PECO's  recovery of stranded  costs is
         based on the level of transition charges  established in the settlement
         of PECO's  restructuring  case and the projected annual retail sales in
         PECO's service  territory.  Recovery of transition charges for stranded
         costs and PECO's  allowed  return on its recovery of stranded costs are
         included in revenues.  In 2002,  revenue  attributable to stranded cost
         recovery  was $850 million and is scheduled to increase to $932 million
         by 2010,  the final year of stranded  cost  recovery.  Amortization  of
         PECO's stranded cost recovery, which is a regulatory asset, is included
         in depreciation and amortization. The amortization expense for 2002 was
         $308 million and will  increase to $879 million by 2010.  Thus,  PECO's
         results will be adversely  affected  over the  remaining  period ending
         December  31,  2010 by the  reduction  in the  unamortized  balance  of
         stranded  costs and therefore the return  received on that  unamortized
         balance.

         Our ability to successfully manage the end of the transition period may
         affect our capital structure.

         ComEd has  approximately  $4.9 billion of goodwill recorded at December
         31, 2002.  This goodwill was recognized and recorded in connection with
         the Merger. Under Generally Accepted Accounting  Principles (GAAP), the
         goodwill will remain at its recorded  amount unless it is determined to
         be impaired,  which is based upon an analysis of ComEd's cash flows. If
         an  impairment  is  determined  at ComEd,  the  amount of the  impaired
         goodwill will be written-off and expensed at ComEd. However, a goodwill
         impairment   charge  at  ComEd  may  not  affect  Exelon's  results  of
         operations.  Exelon's goodwill  impairment test would include assessing
         the cash flows of the entire Energy Delivery business segment (a single
         Reporting   Unit,   which  includes  PECO,  as  defined  under  current
         accounting guidance), not just ComEd's cash flows. Presently, ComEd has
         sufficient  cash flows to support the  recorded  amount of goodwill and
         thus, no impairment has been recorded. For a further discussion on this
         subject,  see the Asset  Impairment  discussion in Critical  Accounting
         Estimates. ComEd's cash flows include CTCs, which will cease at the end
         of 2006,  unless  there  is a  legislative  or  regulatory  change  and
         collections  from  traditional  bundled  customers  at tariffed  rates.
         Absent  another  source  of  revenues  to  replace  the loss of the CTC
         revenue,  all or a portion of the goodwill may become  impaired.  ComEd
         currently  believes that there are a number of alternatives  that could
         provide cash flows to support the goodwill.  Under current regulations,
         a significant  goodwill  impairment may restrict ComEd's ability to pay
         dividends  (see Credit Issues in Liquidity and Capital  Resources).  We
         are  pursuing  various  solutions  to  address  ComEd's  ability to pay
         dividends if a significant goodwill impairment exists.  However,  based
         on  Illinois  legislation,   goodwill  impairments  are  excluded  from
         determining  whether  or not the  earnings  cap  amount has been met or
         exceeded (see Energy Delivery - Equity Return Limitations).

         Weather  affects  electricity and gas usage and,  consequently,  Energy
         Delivery's results of operations.

         Temperatures above normal levels in the summer tend to further increase
         summer cooling electricity demand and revenues,  and temperatures below
         normal  levels in the winter tend to further  increase  winter  heating
         electricity  and gas demand and revenues.  Because of seasonal  pricing
         differentials,  coupled with higher  consumption  levels,  we typically
         report  higher  revenues  in the  third  quarter  of our  fiscal  year.
         However,   extreme   summer   conditions   or  storms  may  stress  our
         transmission   and   distribution   systems,   resulting  in  increased
         maintenance  costs and  limiting  our ability to bring power in to meet
         peak customer  demand.  These extreme  conditions may have  detrimental
         effects on our operations.

         Economic   conditions  and  activity  in  Energy   Delivery's   service
         territories directly affect the demand for electricity.

         Higher levels of development and business activity  generally  increase
         the number of  customers  and their use of energy.  Sales  growth on an
         annual  basis is  expected  to be 1.5% and 0.6% in  ComEd's  and PECO's
         service territories,  respectively. In the long-term, output growth for
         electricity  is  expected  to be 1.2%  per year  for  Energy  Delivery.
         However, there is continued economic uncertainty. Recessionary economic
         conditions, and the associated reduced economic activity, may adversely
         affect our results of operations.

         Our business is affected by the restructuring of the energy industry.

                                       10


         The electric utility industry in the United States is in transition. As
         a  result  of both  legislative  initiatives  as  well  as  competitive
         pressures,  the  industry  has  been  moving  from  a  fully  regulated
         industry,  consisting primarily of vertically integrated companies that
         combine  generation,  transmission  and  distribution,  to a  partially
         restructured  industry,  consisting of competitive wholesale generation
         markets and continued  regulation  of  transmission  and  distribution.
         These  developments  have been  somewhat  uneven across the states as a
         result of the reaction to the problems  experienced  in  California  in
         2000  and  the  more  recently   publicized  problems  of  some  energy
         companies.  Both Illinois and Pennsylvania  have adopted  restructuring
         legislation  designed  to  foster  competition  in the  retail  sale of
         electricity. A large number of states have not changed their regulatory
         structures.

               o    Regional Transmission Organizations / Standard Market Design

                  To facilitate wholesale  competition in the electric industry,
                  FERC has  required  jurisdictional  utilities  to provide open
                  access  to  their   transmission   systems.   To  foster   the
                  development of large regional wholesale  markets,  FERC issued
                  Order   2000,   encouraging   the   development   of  regional
                  transmission organizations (RTOs) and the elimination of trade
                  barriers between regions.  FERC has also proposed  rulemakings
                  to mandate a standard  market  design (SMD) for the  wholesale
                  markets. Order 2000 and the proposed SMD rule contemplate that
                  the jurisdictional  transmission  owners in a region will turn
                  over operating authority over their transmission facilities to
                  an  RTO  or  other  independent  entity  for  the  purpose  of
                  providing  open  transmission   access.   As  a  result,   the
                  independent   entity   will   become  the   provider   of  the
                  transmission  service and the transmission owners will recover
                  their revenue requirements through the independent entity. The
                  transmission  owners will remain  responsible  for maintaining
                  and physically  operating their transmission  facilities.  The
                  SMD rulemaking  proposal would also require RTOs to operate an
                  organized  bid-based  wholesale  market  for those who wish to
                  sell their  generation  through the market and to  implement a
                  financially-based   system  for  dealing  with  congestion  on
                  transmission  lines  known as  "locational  marginal  pricing"
                  (LMP).  FERC  has  also  issued  proposals  to  encourage  RTO
                  development,  independent control of the transmission grid and
                  expansion  of the  transmission  grid  by  providing  enhanced
                  returns on equity for transmission assets.

                  PECO  is a  member  of  PJM  Interconnection,  LLC  (PJM),  an
                  approved RTO  operating  in the  Mid-Atlantic  region.  ComEd,
                  along  with  other  Midwestern  utilities,  joined  PJM  in  a
                  westward  expansion  of PJM.  ComEd is  expected  to turn over
                  control of its transmission  assets to PJM later this year and
                  recover  its  current  transmission  revenues  through the PJM
                  open-access transmission tariff.

                  FERC Order 2000 has not led to the rapid  development  of RTOs
                  and FERC has not yet finalized  its SMD proposal,  due in part
                  to substantial  opposition by some state  regulators and other
                  governmental officials. We support both of these proposals but
                  cannot predict  whether they will be  successful,  what impact
                  they may ultimately have on our transmission  rates,  revenues
                  and operation of our transmission facilities,  or whether they
                  will ultimately  lead to the development of large,  successful
                  regional wholesale markets.  To the extent that ComEd and PECO
                  have POLR  obligations,  and may at some point no longer  have
                  long-term supply contracts with Generation for their load, the
                  ability of ComEd and PECO to cost effectively serve their POLR
                  load  obligation  will  depend  on  the  development  of  such
                  markets.

                                       11


         Effective management of capital projects is important to our business.

         Energy   Delivery's   business  is  capital   intensive   and  requires
         significant   investments  in  energy   transmission  and  distribution
         facilities, and in other internal infrastructure projects.

         Energy Delivery continues to make significant  capital  expenditures to
         improve the reliability of its transmission and distribution systems in
         order to  provide a high  level of  service  to its  customers.  Energy
         Delivery expects that its capital  expenditures will continue to exceed
         depreciation  on its plant assets.  Energy  Delivery's base rate freeze
         and caps will generally  preclude  incremental  rate recovery on any of
         these  incremental  investments  prior to January  1, 2007 (see  Energy
         Delivery - Rate and Equity Return Limitations above).

Generation

         Our  Generation  business  operates  a fleet of  generating  assets and
markets the output of a portfolio of supply,  which  includes 100% owned assets,
co-owned facilities and purchased power. As discussed previously, Generation has
entered  into  long-term  power  purchase  agreements  with ComEd and PECO.  The
majority  of  Generation's  portfolio  is  used to  provide  power  under  these
agreements.  To the extent the  portfolio is not needed to supply power to ComEd
or PECO, their output is sold on the wholesale market.  Generation's  ability to
grow is dependent upon its ability to  cost-effectively  meet ComEd's and PECO's
load  requirements,  to manage its power portfolio and to effectively handle the
changes in the wholesale power markets.

         Our financial  performance may be affected by liabilities  arising from
         our ownership and operation of nuclear facilities.

         The  ownership  and  operation of nuclear  facilities  involve  certain
         risks,  including:  mechanical  or structural  problems;  inadequacy or
         lapses in maintenance  protocols;  the impairment of reactor  operation
         and safety systems due to human error;  the costs of storage,  handling
         and disposal of nuclear material; and uncertainties with respect to the
         technological   and  financial  aspects  of   decommissioning   nuclear
         facilities  at the end of their useful  lives.  The following are among
         the more significant of these risks:

               o    Operational risk

                  Operations  at any nuclear  generation  plant could degrade to
                  the point where we would have to shut down the plant.  If this
                  were to happen,  the process of identifying and correcting the
                  causes of the  operational  downgrade  to return  the plant to
                  operation   could  require   significant   time  and  expense,
                  resulting  in  both  lost  revenue  and  increased   fuel  and
                  purchased  power expense to meet our supply  commitments.  For
                  plants  operated  by us but not  wholly  owned by us, we could
                  incur  liabilities to the co-owners.  We may choose to close a
                  plant  rather  than incur  substantial  costs to  restart  the
                  plant.

               o    Nuclear accident risk

                  Although the safety  record of nuclear  reactors has been very
                  good,  accidents and other  unforeseen  problems have occurred
                  both in the United States and elsewhere.  The  consequences of
                  an  accident  can be severe and may  include  loss of life and
                  property  damage.  Any  resulting  liability  from  a  nuclear
                  accident   could   exceed   our   insurance    coverages   and
                  significantly  affect our results of  operations  or financial
                  position.  See

                                       12



                  Note 19 of Notes to the Consolidated  Financial Statements for
                  further discussion of nuclear insurance.

               o    Nuclear regulation

                  The Nuclear Regulatory Commission (NRC) may modify, suspend or
                  revoke  licenses  and impose  civil  penalties  for failure to
                  comply with the Atomic Energy Act, the regulations under it or
                  the terms of the  licenses of nuclear  facilities.  Changes in
                  regulations by the NRC that require a substantial  increase in
                  capital  expenditures or that result in increased operating or
                  decommissioning  costs could  adversely  affect our results of
                  operations or financial  condition.  Events at nuclear  plants
                  owned by others,  as well as those  owned by us, may  initiate
                  such actions.  Additional security  requirements could also be
                  imposed.

               o    Plant life extensions

                  In 2001,  Generation  extended the estimated  lives of certain
                  nuclear stations. This change in estimate reflects the current
                  and  planned  applications  to the NRC to renew the  operating
                  licenses of Generation's nuclear stations.  These applications
                  for renewal,  if approved by the NRC, will allow Generation to
                  operate  these plants for an  additional  20 years longer than
                  originally authorized. Nuclear station service life extensions
                  are subject to NRC  approval of an  extension  of existing NRC
                  operating licenses,  which are generally 40 years. We continue
                  to fully  believe  that any such  applications  for renewal of
                  operating licenses will be approved.  However, if the NRC does
                  not extend our  operating  licenses for our nuclear  stations,
                  our  results of  operations  could be  adversely  affected  by
                  increased    depreciation   rates   and   accelerated   future
                  decommissioning payments.

         Generation's  financial performance is affected in large measure by the
         availability and use of its nuclear generation capacity.

               o    Nuclear capacity factors

                  Generation  capacity  factors,  particularly  nuclear capacity
                  factors,  significantly  affect  our  results  of  operations.
                  Nuclear plant operations  involve  substantial fixed operating
                  costs,  but produce  electricity  at low marginal costs due to
                  low  variable  fuel  costs.  Consequently,  to be  successful,
                  Generation must  consistently  operate its nuclear  generating
                  facilities  at high  capacity  factors.  Generation's  nuclear
                  fleet performed at a 92.7% capacity  factor (which  represents
                  the  percentage  of the total  maximum  energy  that  could be
                  produced if facilities were operating full-time year round) in
                  2002 and is targeted to operate at a 94.2% capacity  factor in
                  2003. In calculating  capacity factors,  Generation's  nuclear
                  fleet  includes  the  AmerGen  plants and  excludes  the Salem
                  generation  facility,  which is  operated  by  Public  Service
                  Enterprise Group Incorporated (PSE&G).  Lower capacity factors
                  would   increase  our   operating   costs  and  could  require
                  Generation  to generate  additional  energy from its fossil or
                  hydroelectric  facilities or purchase additional energy in the
                  spot or forward markets in order to satisfy its obligations to
                  Energy Delivery and other committed  third-party  sales. These
                  sources  generally  are  at  a  higher  cost  than  Generation
                  otherwise  would have  incurred  to  generate  energy from its
                  nuclear stations.

               o    Refueling  outage   scheduling  at  nuclear  plants  affects
                    availability and costs

                  Outages at nuclear  stations  to  replenish  fuel  require the
                  station to be "turned off."


                                       13


                  Refueling  outages  are  planned  to occur once every 18 to 24
                  months  and  currently   average   approximately  22  days  in
                  duration.  We  have  significantly  decreased  the  length  of
                  refueling  outages in recent years.  However,  when  refueling
                  outages  last  longer  than   anticipated   or  we  experience
                  unplanned outages,  we face lower margins due to higher energy
                  replacement  costs and/or lower energy sales.  Each twenty-day
                  outage,  depending  on  the  capacity  of  the  station,  will
                  decrease the total nuclear annual capacity factor between 0.1%
                  and 0.4%. The number of refueling outages,  including AmerGen,
                  will   decrease   to  eight  in  2003  from  eleven  in  2002.
                  Maintenance and capital  expenditures are expected to decrease
                  by approximately $45 million and $10 million, respectively, in
                  2003  as  compared  to  2002  as a  result  of  fewer  nuclear
                  refueling outages.

         Generation is directly affected by wholesale energy prices.

         Generation  sells energy in the  wholesale  markets  after  meeting its
         contractual  commitments to Energy  Delivery and other  parties.  These
         sales expose  Generation  to the risks of rising and falling  prices in
         those  markets,  and cash  flows may vary  accordingly.  The  amount of
         generation  capacity that is exposed to the volatility of market prices
         depends  inversely  on the  level  of  demand  in the  Energy  Delivery
         companies.

         The wholesale  prices of  electricity  have  generally  been lower than
         historical  levels over the last few years.  A  continued  trend of low
         wholesale  electricity  prices  could  negatively  affect  our  overall
         results of  operations.  Factors that affect  wholesale  energy  prices
         include  the overall  demand for  energy,  fossil fuel costs and excess
         capacity within the industry.

               o    Demand for energy

                  An  increased  demand for energy will  normally  cause  energy
                  prices to increase; however, if this increase in demand drives
                  an incremental  increase in supply,  energy prices may be less
                  affected.  The  demand  for  energy is  directly  affected  by
                  weather  conditions  and  economic  conditions  in our service
                  territories.

                    o    Weather conditions

                           Generation's  operations  are  affected  by  weather,
                           which  affects  demand  for  electricity  as  well as
                           operating  conditions.  We manage our business  based
                           upon normal weather  assumptions.  To the extent that
                           weather  is  warmer  in the  summer  or colder in the
                           winter  than  we  assumed,   Generation  may  require
                           greater    resources   to   meet   its    contractual
                           requirements  to  Energy  Delivery.   Extreme  summer
                           conditions or storms may affect the  availability  of
                           generation   capacity  and   transmission,   limiting
                           Generation's  ability  to send  power  to where it is
                           sold. These conditions, which may not have been fully
                           anticipated,  may  adversely  affect  us  by  causing
                           Generation to seek additional capacity at a time when
                           wholesale markets are tight or to seek to sell excess
                           capacity  at a time  when  those  markets  are  weak.
                           Generation does  incorporate  contingencies  into its
                           planning for extreme  weather  conditions,  including
                           reserving  capacity  to meet  summer  loads at levels
                           representative   of  warmer   than   normal   weather
                           conditions.

                    o    Economic conditions

                           Economic conditions and activity in Energy Delivery's
                           service  territories  directly  affect the demand for
                           electricity and gas.  Changes in economic  conditions
                           and


                                       14


                           activity in Energy Delivery's service territories and
                           in other  parts of the  United  States can affect the
                           level  of  operations   required  in  our  generating
                           facilities  as  well  as  the  prevailing  prices  of
                           electricity and gas in the wholesale markets in which
                           we do business.

          o    Fossil fuel costs

                  At  any  given  time,  the  open  market  wholesale  price  of
                  electricity is affected by the cost of supplying one more unit
                  of electricity to the market at that time. Many times the next
                  unit of electricity supplied would be supplied from generating
                  stations  fueled  by  fossil  fuels,  primarily  natural  gas.
                  Consequently,  the open market  wholesale price of electricity
                  may reflect the cost of gas plus the spark spread, the cost to
                  convert gas to electricity.  Therefore, changes in the cost of
                  gas may impact the open market wholesale price of electricity.

          o    Excess capacity

                  In  addition  to being  affected  by  demand  factors  such as
                  weather, the economy, and fossil fuel costs, energy prices are
                  also  impacted by the amount of supply  available in a region.
                  In  the  markets  where  we  sell  power,  there  has  been  a
                  significant  increase in the number of new power plants coming
                  on-line  which has driven down power  prices over the last few
                  years. In fact, an "excess supply" problem currently exists in
                  many parts of the country.  A key factor for  Exelon's  future
                  earnings  is the timing of a return to more  normal  levels in
                  the supply-demand balance within the regions where we operate.

         The scope and scale of our nuclear generation  resources provide a cost
         advantage in meeting our contractual  commitments and enable us to sell
         power in the wholesale markets.

         The  generation  assets  transferred  to  Generation  by ComEd and PECO
         during the 2001  restructuring,  the generating plants acquired in 2002
         and  Generation's  investments in Sithe and AmerGen  provide a critical
         mass  of  generation  capacity  and a  leadership  position  in  energy
         wholesale markets.  Generation's resources,  including AmerGen, include
         interest in 11 nuclear  generation  stations,  consisting  of 19 units,
         which generated  125,916 GWhs, or more than half of our total supply in
         2002. As the largest  generator of nuclear power in the United  States,
         we can take  advantage  of our scale and scope to  negotiate  favorable
         terms  for the  materials  and  services  that our  business  requires.
         Generation's  nuclear  plants  benefit from stable fuel costs,  minimal
         environmental impact from operations, and a safe operating history.



                                       15


         Our  financial   performance   will  be  affected  by  our  ability  to
         effectively  operate and integrate the assets of Sithe New England into
         our business and to market the output.

         In November 2002,  Generation  acquired the generating  assets of Sithe
         New England  Holdings,  LLC (Sithe New England).  The Sithe New England
         assets,  now known as the Exelon New England Holdings  assets,  include
         2,421 MWs of  gas-fired  combined  facilities  under  construction  and
         several operating generating facilities, which together with the assets
         under  construction  total 4,066 MWs of capacity.  The facilities under
         construction  (Mystic 8, Mystic 9, and Fore River) are currently in the
         final stages of  construction  and testing.  We  anticipate  commercial
         operation dates during the second quarter of 2003.  These projects have
         experienced  delays  in  construction  and  any  further  delays  could
         adversely  affect our  results.  See  further  discussion  of the Sithe
         Boston Generation Project Debt in Liquidity and Capital Resources. With
         the continued  low  wholesale  energy  prices,  we anticipate  that the
         effects  of the Sithe  New  England  acquisition  will be  dilutive  to
         earnings by approximately $125 million in 2003.

         Power Team has not fully  committed  the output  from these  facilities
         into the New England markets. As such, the uncommitted  capacity of the
         Exelon New England  Holdings  assets is subject to the  fluctuations in
         market demand and market prices.

         Substantially  all of the  natural  gas  requirements  for Mystic 8 and
         Mystic 9 will be supplied  through a  twenty-year  natural gas contract
         that  became   effective   on  December  1,  2002  with   Distrigas  of
         Massachusetts,  LLC (Distrigas).  The Distrigas facilities consist of a
         liquefied  natural gas (LNG) import  terminal  located  adjacent to the
         Mystic station.  We are anticipating an additional  pipeline gas supply
         arrangement  to supplement LNG supplies to be in service by early 2005.
         In the  interim,  any  disruption  in  LNG  supplies  to the  Distrigas
         facilities  could  restrict  the  operating  abilities  of Mystic 8 and
         Mystic 9.

         The interaction  between our Energy Delivery and Generation  businesses
         provide us a partial hedge.

         The  price of power  purchased  and sold in the open  wholesale  energy
         markets can vary significantly in response to market  conditions.  Both
         ComEd and PECO have  entered  into  long-term  agreements  for the next
         several  years  with  Generation  to procure  the power at fixed  rates
         needed to meet the demand of their  customers.  The amounts provided to
         affiliates vary from month to month; however, delivery requirements are
         generally  highest in the summer when  wholesale  power prices are also
         generally highest.  Therefore, energy committed to serve ComEd and PECO
         customers is not exposed to the price uncertainty of the open wholesale
         energy market.  Consequently,  we have limited our earnings exposure to
         the volatility of the wholesale  energy market to the energy  generated
         beyond the ComEd and PECO requirements, as well as any other contracted
         longer  term  obligations.  Generally,  between  60%  and  70%  of  our
         generation  serves ComEd and PECO  customers.  We expect such levels to
         decrease to between 55% and 60% as a result of activating  the acquired
         Sithe New England plants,  which are currently under construction.  One
         of the  responsibilities  of  Power  Team  is to  establish  a  hedging
         strategy,  incorporating  the load obligations of Energy  Delivery,  to
         minimize the contracted  volatility of our earnings and cash flows, and
         to maximize the value of economic  generation  in excess of that needed
         to serve ComEd and PECO requirements.

         Our  financial  performance  depends  on  our  ability  to  respond  to
         competition in the energy industry.

                                       16


         As a result of industry  restructuring,  numerous generation  companies
         created by the disaggregation of vertically  integrated  utilities have
         become active in the wholesale power generation business.  In addition,
         independent   power  producers  (IPP)  have  become  prevalent  in  the
         wholesale  power  industry.  In recent years,  IPPs and the  generation
         companies of  disaggregated  utilities  have  installed new  generating
         capacity at a pace greater than the growth of electricity  demand. As a
         result, the energy generation business is currently suffering from over
         capacity  in certain  parts of the  country,  which  reduces  wholesale
         energy  prices.  As discussed  above,  we are well  positioned  because
         Generation has entered into  agreements for the next several years with
         ComEd  and PECO to sell the power  needed  to meet the  demand of their
         customers. These agreements provide a mechanism to enhance stability in
         our  earnings  and  limit  our  exposure  to the  negative  effects  of
         wholesale markets.

         The commencement of commercial  operation of new generating  facilities
         in the regional  markets  where we have  facilities  or  contracts  for
         power,  such  as  the  Midwest,   Mid-Atlantic,   Northeast  and  South
         (including certain sections of Texas),  would likely decrease wholesale
         power  market  prices in those  regions,  which  could  have a negative
         effect on our business and results of operations.

         Our financial performance may be affected by the marketing, trading and
         risk management activities of Power Team.

         Generation's wholesale marketing unit, Power Team,

          o    uses our energy generation portfolio, transmission rights and its
               power  marketing  expertise  to  manage  delivery  of  energy  to
               wholesale customers,  including Energy Delivery,  under long-term
               and short-term contracts,
          o    participates  in the  wholesale  energy  market to hedge our open
               energy (power and fossil fuels)  positions,
          o    manages  commodity and counterparty  credit risks through the use
               of  documented  risk and credit  policies,  and
          o    uses its energy market expertise to engage in trading  activities
               for speculative purposes on a limited basis.

         Power Team has  substantial  experience in energy  markets,  generation
         dispatch and the requirements for the physical delivery of power. Power
         Team  may buy  power  to  meet  the  energy  demand  of its  customers,
         including  Energy  Delivery.  These purchases may be made for more than
         the energy  demanded by Power Team's  customers.  Power Team then sells
         this open position, along with our generating capacity not used to meet
         our customer demand, in the wholesale energy market.

         Power Team  began  proprietary  trading  activities  in 2001,  but this
         activity accounts for a small portion of Power Team's efforts. In 2002,
         proprietary  trading  activities  resulted in an $18 million  after-tax
         reduction  in  our  earnings.  We  will  continue  proprietary  trading
         activities  but in a more  limited  capacity  given the current lack of
         liquidity  of  power  markets  and  reduced   number  of   creditworthy
         counterparties.

         Power  Team  has  managed  to  avoid  the  recent  managerial  problems
         experienced in the energy trading industry through the strict adherence
         to prudent risk management  practices.  However, the recent failures of
         energy  companies and their related energy  trading  practices over the
         last year have  diminished  the size and depth of the wholesale  energy
         market.  We cannot predict how this will affect our trading  operations
         in the future.

                                       17


         We depend on counterparties fulfilling their obligations.

         Our trading,  marketing and  contracting  operations are exposed to the
         risk that  counterparties,  which owe us money or energy as a result of
         market  transactions,  will not perform their obligations.  In order to
         evaluate  the  viability  of our  counterparties,  we have  implemented
         credit  risk  management  procedures  designed  to  mitigate  the risks
         associated  with these  transactions.  Energy  supplied by  third-party
         generators,  including  AmerGen and Sithe,  under long-term  agreements
         represents a  significant  portion of  Generation's  overall  capacity.
         These third-party  generators face operational risks such as those that
         Generation  faces,  and their  ability to perform also depends on their
         financial   condition.   In  the  event  the  counterparties  to  these
         arrangements  fail  to  perform,  we  might  be  forced  to  honor  the
         underlying   commitment  at   then-current   market  prices  and  incur
         additional  losses,  to the extent of amounts,  if any, already paid to
         the counterparties. 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. These agreements 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.

         See  the  Credit  Risk  section  in the  Quantitative  and  Qualitative
         Disclosures  about  Market  Risk for  further  discussions  on specific
         credit  risk  matters  such as our  potential  counterparty  exposures,
         including Dynegy Inc. (Dynegy).

         Generation's  business  is also  affected by the  restructuring  of the
         energy industry.

          o    Regional Transmission Organizations / Standard Market Design

                  Generation is dependent on wholesale  energy  markets and open
                  transmission  access and  rights by which we deliver  power to
                  our wholesale customers,  including ComEd and PECO. We use the
                  wholesale regional energy markets to sell power that we do not
                  need to satisfy our long-term contractual obligations, to meet
                  long-term  obligations not provided by our own resources,  and
                  to take advantage of price opportunities.

                  Wholesale  spot markets have only been  implemented in certain
                  areas of the country and each market has unique  features that
                  may create trading barriers between the markets. Although FERC
                  has  proposed  initiatives,   including  Order  2000  and  the
                  proposed  SMD rule,  to  encourage  the  development  of large
                  regional,  uniform  markets and to eliminate  trade  barriers,
                  these  initiatives have not yet led to the development of such
                  markets  all  across  the  country.   PJM's  market   strongly
                  resembles   FERC's   proposal,   and  both  the  New   England
                  Independent   System  Operator   (NE-ISO)  and  the  New  York
                  Independent  System operator (NYISO) are  implementing  market
                  reforms. We strongly encourage the development of standardized
                  energy markets and support FERC's  standardization  efforts as
                  being  essential  to  wholesale   competition  in  the  energy
                  industry and to Generation's  ability to compete on a national
                  basis  and  to  meet  its  long-term  contractual  commitments
                  efficiently.


                                       18


                  Approximately  26% of our generation  resources are located in
                  the region  encompassed  by PJM. If the PJM market is expanded
                  to the  Midwest,  82% of our  current  assets  will be located
                  within the expanded  market.  The PJM market has been the most
                  successful   and  liquid   regional   market  and  is  largely
                  consistent  with the standard  market design proposed by FERC.
                  Our  future  results  of  operations  may be  impacted  by the
                  successful  expansion  of that  market to the  Midwest and the
                  implementation of any market changes mandated by FERC.

          o    Provider of Last Resort

                  As noted,  Energy  Delivery has a POLR  obligation that it has
                  largely assigned to Generation  through the full  requirements
                  contracts  that it has with  Generation.  Currently both ComEd
                  and PECO have entered into purchase  power  agreements  (PPAs)
                  with  Generation  to provide 100% of their  respective  energy
                  requirements.  ComEd's PPA with  Generation is for 100% of its
                  required  load through 2004 at fixed  prices,  and in 2005 and
                  2006 it equals  100% of the output of ComEd's  former  nuclear
                  plants, now owned by Generation at market based prices. PECO's
                  PPA  with  Generation  is a full  load  requirements  contract
                  through  2010.  We intend to revise the PPA between  ComEd and
                  Generation  to be a full  requirements  contract  in 2005  and
                  2006.  Additionally,  the PPAs between  Generation,  ComEd and
                  PECO may be extended  beyond their current  expiration  dates.
                  ComEd  and PECO  continue  to work on  resolution  of the POLR
                  issues with their respective state regulatory  commissions and
                  other market participants.

         Effective  management of capital  projects is important to Generation's
         business.

         Generation's  business is capital  intensive  and requires  significant
         investments in energy  generation and in other internal  infrastructure
         projects.  As  mentioned  previously,  as part of  Generation's  recent
         acquisition  of the assets of Sithe New England,  Generation  is in the
         process  of  completing  the  construction  of  three   high-efficiency
         generating  facilities with projected  capacity of 2,421 MWs of energy.
         The inability to effectively  manage the capital projects,  such as the
         Sithe New England  facilities,  could adversely affect our results from
         operations.


Enterprises

         Enterprises'  results of  operations  may be affected by its ability to
         strategically divest itself of certain businesses.

         Enterprises  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 amounts that  Enterprises may
         realize from a divestiture are 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 our results of
         operations  as we expect  certain  businesses  to be  profitable  going
         forward.

         Enterprises may incur further impairments of its investments.

         Enterprises  wrote down $41 million of investments in 2002 when certain
         events  occurred,  such  as  competitors'   technological  advancement,
         accelerated  distributions  of  public  holdings  at a  loss,  lack  of
         achievability  of financial  results  versus plan and limited access to
         capital markets. At

                                       19


         December 31, 2002, Enterprises held $128 million of investments.  These
         types of events,  or others,  could  continue  to occur in 2003,  which
         could result in additional impairment charges.

         Enterprises'  results of  operations  may be affected by its ability to
         manage its projects.

         Enterprises   consists  of  many  businesses  that  utilize   long-term
         fixed-price  contracts.  At the beginning of the contract,  we estimate
         the total costs and profits of the  contract;  if the actual costs vary
         significantly  form the  estimates,  our results of operations  will be
         adversely impacted.  Along with our ability to execute,  results may be
         impacted by economic conditions,  weather conditions and the regulatory
         environment.


Capital Markets / Financing Environment

         In order to expand our  operations and to meet the needs of our current
and future  customers,  we invest in our businesses.  Our ability to finance our
businesses and other necessary expenditures is affected by the capital intensive
nature of our operations and our current and future credit ratings.  The capital
markets also affect our decommissioning trust funds and benefit plan assets. Our
financing  needs will be  dependent  on our  strategic  direction  of  acquiring
integrated  utilities and generation  facilities,  and our ability to dispose of
unprofitable  businesses that do not advance our goals.  Further  discussions on
our  liquidity  position  can be found in the  Liquidity  and Capital  Resources
section.

         Our ability to grow our  business is affected by our ability to finance
capital projects.

         Our businesses require considerable capital resources.  When necessary,
         we secure funds from external sources by issuing  commercial paper and,
         as required, long-term debt securities. We actively manage our exposure
         to changes in interest rates through  interest-rate  swap  transactions
         and our balance of fixed- and floating-rate  instruments.  We currently
         anticipate   primarily  using  internally   generated  cash  flows  and
         short-term financing through commercial paper to fund our operations as
         well  as  long-term   external   financing   sources  to  fund  capital
         requirements  as the needs and  opportunities  arise.  Our  ability  to
         arrange debt  financing,  to  refinance  current  maturities  and early
         retirements  of debt,  and the costs of issuing new debt are  dependent
         on:

          o    credit availability from banks and other financial  institutions,
          o    maintenance of acceptable  credit ratings (see Our Credit Ratings
               below),
          o    investor  confidence  in  us,
          o    investor  confidence in other regional wholesale power markets, o
               general economic and capital market conditions,
          o    the success of current  projects,  and o the perceived quality of
               new projects.


                                       20


         Our credit ratings influence our ability to raise capital.

         Our businesses have  investment  grade ratings and have been successful
         in  raising  capital,  which  has been  used to  further  our  business
         initiatives.  Also,  from time to time, we enter into energy  commodity
         and other  contracts that require the  maintenance of investment  grade
         ratings.  Failure to maintain investment grade ratings would require us
         to incur  higher  financing  costs  and  would  allow,  but not in most
         instances  require,  counterparties  to energy  commodity  contracts to
         terminate the contracts and settle the  transaction.  Also, the failure
         to maintain  investment  grade ratings would restrict our access to the
         wholesale energy markets.

         Equity market performance affects our  decommissioning  trust funds and
         benefit plan asset values.

         The sharp decline in the equity markets since the third quarter of 2000
         has  reduced  the value of the  assets  held in trusts to  satisfy  the
         obligations  of  pension  and  postretirement  benefit  plans  and  the
         eventual nuclear generation station  decommissioning  requirements.  If
         the  markets   continue  to  decline,   we  may  have  higher   funding
         requirements and pension and other  postretirement  benefit expense. We
         will  continue to manage the assets in the  pension and  postretirement
         benefit  plans and nuclear  decommissioning  trusts in order to achieve
         the  best  return  possible  in  conjunction   with  our  overall  risk
         management  practices and  diversified  approach to investment.  Please
         refer to the  Critical  Accounting  Estimates  section  that more fully
         describes the quantitative  financial  statement  effects of changes in
         the  equity  markets on the  nuclear  decommissioning  trust  funds and
         benefit plan assets.

         Our results of operations can be affected by inflation.

         Inflation  affects us through  increased  operating costs and increased
         capital costs for electric  plant.  As a result of the rate freezes and
         caps imposed under the  legislation  in Illinois and  Pennsylvania  and
         price  pressures  due to  competition,  we may not be able to pass  the
         costs of inflation through to customers.

Other

         We may incur  substantial  cost to fulfill our  obligations  related to
         environmental matters.

         Our  businesses  are subject to extensive  environmental  regulation by
         local, state and Federal authorities. These laws and regulations affect
         the  manner in which we conduct  our  operations  and make our  capital
         expenditures.  These  regulations  affect  how we handle  air and water
         emissions  and solid  waste  disposal  and are an  important  aspect of
         Generation's operations. In addition, we are subject to liability under
         these laws for the costs of remediating environmental  contamination of
         property now or formerly  owned by us and of property  contaminated  by
         hazardous substances we generate. We believe that we have a responsible
         environmental  management  and  compliance  program;  however,  we have
         incurred and expect to incur significant costs related to environmental
         compliance and site  remediation and clean-up.  Remediation  activities
         associated  with   manufactured  gas  plant  operations   conducted  by
         predecessor  companies  will be one source of such costs.  Also, we are
         currently  involved in a number of proceedings  relating to sites where
         hazardous  substances  have  been  deposited  and  may  be  subject  to
         additional proceedings in the future.


                                       21


         As of December 31, 2002,  our reserve for  environmental  investigation
         and remediation  costs was $156 million,  exclusive of  decommissioning
         liabilities.  We have accrued and will continue to accrue  amounts that
         we believe are prudent to cover these environmental liabilities, but we
         cannot  predict  with  any  certainty  whether  these  amounts  will be
         sufficient to cover our  environmental  liabilities.  We cannot predict
         whether we will incur other significant  liabilities for any additional
         investigation  and remediation  costs at additional sites not currently
         identified  by us,  environmental  agencies or others,  or whether such
         costs will be recoverable from third parties.

         Regulations imposed by the Securities and Exchange Commission under the
         Public  Utility  Holding  Company  Act  of  1935  affect  our  business
         operations.

         We are subject to regulation by the Securities and Exchange  Commission
         (SEC) under the Public Utility Holding Company Act (PUHCA) of 1935 as a
         result of our ownership of ComEd and PECO. That regulation  affects our
         ability to:

               o    diversify,  by  generally  restricting  our  investments  to
                    traditional  electric and gas utility businesses and related
                    businesses;

               o    issue securities, by requiring the prior approval of the SEC
                    or for ComEd  and  PECO,  requiring  the  approval  of state
                    regulatory commissions; and

               o    engage in  transactions  among our  affiliates  without  the
                    SEC's prior  approval  and,  then,  only at cost,  since the
                    PUHCA  regulates  business  between  affiliates in a utility
                    holding  company  system;  and  make  dividend  payments  in
                    specified situations.

         Our  financial  performance  is affected by our ability to manage costs
         for security and liability insurance.

          o    Security

                  We do not fully know the impact that future terrorist  attacks
                  or threats of  terrorism  may have on our  industry in general
                  and on us in particular. The events of September 11, 2001 have
                  affected our operating procedures and costs. We have initiated
                  security  measures to  safeguard  our  employees  and critical
                  operations   and  are  actively   participating   in  industry
                  initiatives to identify methods to maintain the reliability of
                  our energy  production  and delivery  systems.  We have met or
                  exceeded all security measures mandated by the NRC for nuclear
                  plants after the September 11, 2001 terrorist  attacks.  These
                  security  measures  resulted in increased costs in 2002 of $19
                  million,  of which  approximately $10 million was capitalized.
                  On a continuing  basis,  we are evaluating  enhanced  security
                  measures at certain critical locations,  enhanced response and
                  recovery  plans and  assessing  long-term  design  changes and
                  redundancy  measures.  Additionally,  the energy  industry  is
                  working with governmental authorities to ensure that emergency
                  plans are in place and critical infrastructure vulnerabilities
                  are  addressed  in order to maintain  the  reliability  of the
                  country's   energy   systems.   These  measures  will  involve
                  additional expense to develop and implement,  but will provide
                  increased  assurances as to our ability to continue to operate
                  under difficult times.

                  In  connection  with the events of  September  11,  2001,  the
                  electric and gas  industries  have also  developed  additional
                  security guidelines.  The electric industry, through the North
                  American  Electric   Reliability  Council  (NERC),   developed
                  physical security guidelines,  which were accepted by the U.S.
                  Department  of  Energy.  In 2003,  FERC is  expected  to issue
                  minimum  standards  to  safeguard  the  electric  grid  system
                  control.  These standards are expected to be effective in 2004
                  and fully  implemented  by  January  2005.  The gas


                                       22


                  industry,  through the  American  Gas  Association,  developed
                  physical  security  guidelines  that were accepted by the U.S.
                  Department  of   Transportation.   We   participated   in  the
                  development of these  guidelines and are using them as a model
                  for our security program.

          o    Nuclear liability insurance

                  The Price-Anderson Act limits the liability of nuclear reactor
                  owners for claims that could arise from a single incident. The
                  current  limit is $9.5  billion  and is  subject  to change to
                  account for the effects of inflation and changes in the number
                  of licensed reactors.  As required by the Price-Anderson  Act,
                  we carry nuclear liability  insurance in the maximum available
                  amount  (currently  $300 million per site).  Claims  exceeding
                  that amount are covered through  mandatory  participation in a
                  financial  protection pool. The  Price-Anderson Act expired on
                  August 1, 2002, but existing  facilities,  such as those owned
                  and operated by Generation,  remain covered. The U.S. Congress
                  has extended the provisions of the  Price-Anderson Act related
                  to  commercial  facilities  through  2003.  The  extension was
                  passed as part of the Consolidated  Appropriations Resolution,
                  2003,  which will be presented to the  President of the United
                  States  for  his   signature.   The  extension   would  affect
                  facilities  obtaining NRC operating licenses in 2003. Existing
                  facilities are unaffected by the extension.

          o    Other insurance

                  In  addition  to  nuclear  liability  insurance,  Exelon  also
                  carries  property  damage  and  liability  insurance  for  its
                  properties and operations.  As a result of significant changes
                  in the insurance marketplace, due in part to the September 11,
                  2001 terrorist acts, the available  coverage and limits may be
                  less than the amount of  insurance  obtained in the past,  and
                  the recovery for losses due to terrorists acts may be limited.
                  We are self-insured for deductibles and to the extent that any
                  losses may exceed the amount of insurance maintained.

                  A claim that exceeds the amounts  available under our property
                  damage and liability insurance,  together with the deductible,
                  would  negatively  affect our results of  operations.  Nuclear
                  Electric  Insurance Limited (NEIL), a mutual insurance company
                  to  which  we   belong,   provides   property   and   business
                  interruption  insurance for our nuclear operations.  In recent
                  years,  NEIL  has  made  distributions  to  its  members.  Our
                  distribution for 2002 was $40 million, which was recorded as a
                  reduction  to  Operating  and   Maintenance   expense  on  our
                  Consolidated   Statements  of  Income.  Due  in  part  to  the
                  September  11, 2001 events and the results in the stock market
                  over the last two years, we cannot predict the level of future
                  distributions.

         The  possibility  of attack or war may adversely  affect our results of
         operations, future growth and ability to raise capital.

         Any  military  strikes or  sustained  military  campaign may affect our
         operations in unpredictable  ways, such as further changes in insurance
         markets,  increased  security measures and disruptions of fuel supplies
         and  markets,  particularly  oil and  LNG.  Just the  possibility  that
         infrastructure  facilities,  such as electric generation,  transmission
         and  distribution  facilities,  would be direct targets of, or indirect
         casualties of, an act of terror or war may affect our  operations.  War
         and the possibility of war may have an adverse effect on the economy in
         general.  A lower level of economic  activity might result in a decline
         in energy  consumption,  which may  adversely  affect our  revenues  or
         restrict our future growth.  Instability in the financial  markets as a
         result of war may affect our ability to raise capital.

         The introduction of new technologies could increase  competition within
         our markets.

                                       23


         While demand for  electricity  is generally  increasing  throughout the
         United States,  the rate of  construction  and development of new, more
         efficient,    electric    generation    facilities   and   distribution
         methodologies  may exceed increases in demand in some regional electric
         markets.   The   introduction  of  new   technologies   could  increase
         competition, which could lower prices and have an adverse affect on our
         results of operations or financial condition.


Results of Operations

Year Ended December 31, 2002 Compared To Year Ended December 31, 2001

Net Income and Earnings Per Share

         Net income for 2002  increased  $12 million  compared to 2001.  Diluted
earnings per common share were $4.44 and $4.43 for 2002 and 2001,  respectively.
Net income for 2002 reflects a $230 million charge for the cumulative  effect of
changes  in  accounting  principles  as a result of the  adoption  of  Financial
Accounting  Standards Board (FASB) Statement of Financial  Accounting  Standards
(SFAS) No. 142, "Goodwill and Other Intangible Assets" (SFAS No. 142), while net
income for 2001  reflects  $12  million of income for the  cumulative  effect of
changes in  accounting  principles  as a result of the adoption of SFAS No. 133,
"Accounting for Derivatives and Hedging  Activities"  (SFAS No. 133). See Note 4
of the  Notes to  Consolidated  Financial  Statements  for  further  information
regarding the adoption of SFAS No. 142 and SFAS No. 133.

         Income Before Cumulative Effect of Changes in Accounting  Principles in
2002  increased $254 million,  or 18%,  compared to 2001.  Diluted  earnings per
common share on the same basis  increased  $0.76 per share, or 17%. The increase
reflects  Enterprises' sale of its interest in AT&T Wireless, a 2.6% increase in
retail sales due to a  warmer-than-usual  summer,  an extension of the estimated
service  lives  of  generating   stations,   the   discontinuation  of  goodwill
amortization  as of January 1, 2002  pursuant  to SFAS No. 142,  lower  interest
expense,  and reduced  depreciation  expense  resulting from lower  depreciation
rates at Energy  Delivery.  The increase was partially offset by lower wholesale
energy  prices,  increased  nuclear  refueling  outage costs,  the write-down of
certain investments at Enterprises,  employee severance costs, and other factors
described below.

         The changes in Energy  Delivery's  revenue,  net of purchased power and
fuel expense, for 2002 compared to 2001, included the following:


                                       25


     o    increases in weather normalized volumes of $171 million as a result of
          increases in the number of customers and additional  average usage per
          customer, primarily residential customers,
     o    positive  weather  impacts of $84  million,  primarily  the results of
          warmer than usual summer weather,
     o    changes in  customer  rates  resulting  in a $54  million  decrease to
          revenue, net of purchased power and fuel expense,
     o    favorable  changes due to customer  choice of $30  million,  including
          customers  returning  to PECO as their  energy  supplier,  or  ComEd's
          customers   electing  to  purchase  energy  from  alternative   energy
          suppliers  or  electing  ComEd's  PPO,  under  which   non-residential
          customers can purchase power from ComEd at a market-based rate,
     o    increases in PJM  ancillary  charges of $41 million,  which  decreased
          revenue, net of purchased power and fuel expense,
     o    an $18 million  increase in 2002 purchased power expense for ComEd due
          to an  increase  in the  weighted  average  on-peak/off-peak  cost  of
          electricity,
     o    a 2001  reversal  of a reserve  for  revenue  refunds  of $15  million
          related  to  certain  ComEd  municipal  customers  as  a  result  of a
          favorable FERC ruling, and
     o    an increase in revenue,  net of purchased  power and fuel related to a
          settlement  of CTCs by a large  customer  of PECO in the amount of $11
          million in 2001.

         The changes in operating income for 2002 compared to 2001, included the
following:

     o    reduction in  amortization  expense of $126 million as a result of the
          discontinuance of goodwill  amortization upon the adoption of SFAS No.
          142 on January 1, 2002,
     o    additional  gross  receipts  tax  expense  of $72  million  related to
          additional  revenues and an increase in the gross  receipt tax rate on
          electric revenue  effective  January 1, 2002 (gross receipts taxes are
          recorded in Revenues and Taxes Other Than Income and have no impact on
          net income),
     o    reduction in depreciation  expense of $48 million due to the impact of
          lower depreciation rates at ComEd effective July 1, 2002,
     o    increased  depreciation  expense in 2002 of $34  million due to higher
          plant in service balances,
     o    increase  in  regulatory  asset  amortization  of $30 million in 2002,
          primarily attributable to additional amortization of PECO's CTCs,
     o    reduction in 2002 in the allowance for uncollectible  accounts related
          to a change in accounting estimate of $28 million,
     o    higher  corporate  allocations,  pension  and  postretirement  benefit
          costs, and executive severance costs totaling $22 million in 2002, and
     o    lower  employee  severance  costs  at  PECO  of $18  million  in  2001
          associated with the Merger.

         The changes in income  before  income taxes for 2002  compared to 2001,
included  the  following:



     o    a decrease in interest expense of $119 million primarily  attributable
          to less  outstanding  debt and  refinancing  of existing debt at lower
          interest rates,
     o    lower  interest  income of $74 million  resulting  from lower interest
          rates which is primarily attributable to a note receivable from Unicom
          Investments, Inc., an Exelon subsidiary, and
     o    the  establishment  of a reserve of $12 million in 2002 for a probable
          plant  disallowance  resulting from an audit  performed in conjunction
          with ComEd's delivery service rate case.

         Energy  Delivery's  effective  income  tax rate  was  37.6%  for  2002,
compared  to  40.8%  for  2001.  This  decrease  in the  effective  tax rate was
primarily   attributable   to  a  reduction   in  state  income  taxes  and  the
discontinuation  of goodwill  amortization as of January 1, 2002,  which was not
deductible for income tax purposes in 2001.

n.m. - not meaningful

         The  differences in 2002 electric  retail  revenues as compared to 2001
were attributable to the following:

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.

o    Weather.  The weather  impact was  favorable in 2002  compared to 2001 as a
     result of warmer  summer  weather  in ComEd and PECO  service  territories.
     Cooling  degree  days in the ComEd and PECO  service  territories  were 29%
     higher and 15% higher,  respectively,  in 2002 as compared to 2001.




                                       28


     Heating  degree  days in the ComEd  and PECO  service  territories  were 3%
     higher and 1% higher, respectively, in 2002 as compared to 2001.

o    Customer  Choice.  All ComEd and PECO customers have the choice to purchase
     energy from other 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 other suppliers.  As
     of  December  31,  2002,  13% of  energy  delivered  to  Energy  Delivery's
     customers was provided by alternative  electric suppliers.  On May 1, 2002,
     all ComEd residential customers became eligible to choose their supplier of
     electricity;  however,  as of December 31, 2002,  no  alternative  electric
     supplier had sought  approval  from the ICC and no electric  utilities  had
     chosen to enter the ComEd residential market for the supply of electricity.
     The increase in electric retail  revenues  includes  increased  revenues of
     $226 million from  customers  in  Pennsylvania  who selected or returned to
     PECO as their  electric  supplier.  The increase was partially  offset by a
     decrease in revenues of $131 million from customers in Illinois electing to
     purchase  energy from an alternative  retail  electric  supplier  (ARES) or
     ComEd's PPO.

o    Rate  Changes.  The  decrease  in  revenues  attributable  to rate  changes
     reflects $99 million for the 5% ComEd residential rate reduction, effective
     October 1, 2001, required by the Illinois restructuring legislation and the
     timing of a $60 million  PECO rate  reduction  in effect for 2001 and 2002,
     partially  offset by $50 million  related to an  increase  in PECO's  gross
     receipts  tax rate  effective  January 1, 2002 and the  expiration  of a 6%
     reduction in PECO's rates during the first quarter of 2001.

o    Other Effects. The primary other item impacting revenues in 2002 was an $11
     million settlement of CTCs by a large PECO customer in the first quarter of
     2001.

         The  reduction in wholesale  revenue is primarily  attributable  to the
expiration  of  wholesale  contracts  that ComEd had entered into to support the
open access  program in Illinois and the fact that  wholesale  revenues for 2001
included a reversal of a $15 million  reserve for customer  refunds because of a
favorable FERC ruling in 2001.  The decrease in wholesale  revenue was partially
offset by a $12 million  reimbursement  from Generation  relating to third-party
energy reconciliations.

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


o    Rate  Changes.  The  unfavorable  variance in rates is  attributable  to an
     adjustment of the purchased gas cost recovery by the PUC in December  2001.
     The average rate per mmcf in 2002 was 20% lower than it was in 2001. 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  increases or
     decreases in certain  state taxes not  recovered  in base rates.  Effective
     December  1,  2002,  the PUC  approved a  reduction  in the  purchased  gas
     adjustment of 4.5%.


                                       29


o    Weather. The weather impact was favorable, as a result of colder weather in
     2002, as compared to 2001. Heating  degree-days in PECO's service territory
     increased 1% in 2002 compared to 2001.
o    Volume.  Exclusive of weather  impacts,  higher delivery  volume  increased
     revenue  by $1  million  in 2002  compared  to 2001.  Total  deliveries  to
     customers  increased 5% in 2002 compared to 2001,  primarily as a result of
     customer growth and higher transportation volumes.

Results of Operations - Generation

         Generation  is one  of  the  largest  competitive  electric  generation
companies  in the  United  States,  as  measured  by owned and  controlled  MWs.
Generation  combines its large  generation  fleet with an experienced  wholesale
power  marketing  operation.  During 2002,  Generation  acquired the  generating
assets of Sithe New England as well as two  generating  stations  from TXU Corp.
Including those acquisitions,  Generation directly owns generation assets in the
Northeast, Mid-Atlantic, Midwest and Texas regions with a net capacity of 26,762
MWs including 14,547 MWs of nuclear  capacity,  and also controls another 13,900
MWs of capacity in the Midwest,  Southeast  and South  Central  regions  through
long-term contracts.

         In addition to its owned generation facilities, Generation owns a 49.9%
interest in Sithe with a call option,  that first  became  available in December
2002,  to purchase the  remaining  50.1%  interest  (see further  discussion  in
Liquidity  and  Capital  Resources).   Sithe  develops,  owns  and  operates  22
generation facilities in North America.  Currently, Sithe has a total generating
capacity of 1,321 MWs in operation  and 230 MWs under  construction.  Generation
also owns a 50% interest in AmerGen,  a joint  venture with British  Energy plc.
AmerGen owns three nuclear stations with total generation capacity of 2,481 MWs.

         Generation's  wholesale  marketing unit,  Power Team, a major wholesale
marketer of energy, uses Generation's energy generation portfolio,  transmission
rights and  expertise  to ensure  delivery of energy to  Generation's  wholesale
customers  under  long-term  and  short-term   contracts,   including  the  load
requirements of ComEd and PECO.  Power Team markets any remaining  energy in the
wholesale and spot markets.

         In the second quarter of 2002, Generation early adopted 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
FASB 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 2002 compared to 2001, included the following:

     o    lower margins on market sales  attributable  to lower  average  market
          energy prices,

                                       30


     o    increased  net  trading  portfolio  losses of $36 million due to lower
          trading  margins  primarily  resulting from lower  purchased power and
          transmission costs, together with lower wholesale market prices,
     o    weather-related increases in sales to affiliates,
     o    lower average supply costs, and
     o    increased market sales volumes.

     The changes in  operating  income for 2002  compared to 2001,  included the
following:

     o    costs incurred for five additional refueling outages of $80 million,
     o    higher allocated corporate costs, including executive severance,
     o    increase in 2002 in the allowance for  uncollectible  accounts related
          to a change in accounting estimate of $6 million,
     o    decrease in depreciation  and  decommissioning  expense of $42 million
          reflecting  the  extension  by  Generation  in 2001  of the  estimated
          service lives of its generating  stations,
     o    additional  depreciation  expense of $32 million on generating  plants
          placed in service,  including two generating plants that were acquired
          in April 2002 and a peaking facility placed in service in July 2002,
     o    costs related to additional security measures of $9 million,
     o    reduction in Generation's severance accrual of $10 million,
     o    decrease in expenses of $8 million related to fewer employees, and
     o    cost reductions related to the Cost Management Initiative.

     The  changes  in income  before  income  taxes for 2002  compared  to 2001,
included the  following:

     o    improved  decommissioning  trust investment  income during 2002 to $58
          million, compared to losses of $60 million in 2001, and
     o    net decrease in interest expense due to:
          o    increased long-term debt resulting in a $21 million increase and
          o    reduction in the variable interest rate on the spent nuclear fuel
               obligation resulting in a decrease of $19 million.

     Generation's effective income tax rate was 35.9% for 2002 compared to 39.0%
for 2001.  This  decrease was  primarily  attributable  to  tax-exempt  interest
deductions in 2002 and other tax benefits recorded in 2002.

     Cumulative effect of changes in accounting  principles recorded in 2002 and
2001  included  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, and income of $12 million,  net of income  taxes,  recorded in
2001  related  to the  adoption  of SFAS No.  133.  See  Note 4 of the  Notes to
Consolidated Financial Statements for further discussion of these effects.

     The factors  below  contributed  to the overall  reduction in  Generation's
average margin for 2002.

     Generation's  GWh  deliveries  increased  5.8%  in  2002  primarily  due to
favorable  weather  conditions,  which increased  demand for Energy Delivery and
increased  market  sales  attributable  to the  increased  supply from  acquired
generation  and power  uprates  at  existing  facilities,  slightly  offset by a
decrease in sales to Exelon  Energy,  Enterprises'  retail  energy unit,  due to
lower demand in the eastern energy markets.

     Generation's supply mix changed due to:

     o    increased purchases resulting from the supply agreement with AmerGen's
          Unit No. 1 at Three Mile Island Nuclear Station facility which was new
          in 2002,
     o    decreased  nuclear  generation  due to an  increase  in the  number of
          refueling outages during 2002, slightly offset by power uprates,
     o    increased  Fossil  and Hydro net  generation  due to the effect of the
          acquisition  of two  generating  plants in April,  a peaking  facility
          placed in service in July and the Sithe New England plants acquired in
          November,  which in total  account for an increase of 2,500 GWhs,  and
          strong waterflows which increased the hydro output by 400 GWhs, and
     o    lower production in our Mid-Atlantic  coal and oil units due to cooler
          summer weather conditions and lower power prices in 2002.

     Generation's average revenue was affected by:

     o    increased  weighted  average on and off peak prices per MWh for supply
          agreements with ComEd,
     o    higher contracted prices from Exelon Energy,  impacted by lower actual
          volumes to those customers, and
     o    lower market prices.

     The lower nuclear  capacity factor and increased  nuclear  production costs
are primarily due to 260 days of planned  outage time in 2002 versus 153 days in
2001.  Nuclear  production cost increased from $12.78 to $13.00 primarily due to
an $80 million  increase in outage costs and the number of refueling



                                       33



outages in 2002 as compared to 2001.  These  decreases are slightly  offset by a
$25 million decrease in payroll costs due to headcount reductions and $4 million
in lower  project  expenditures.  The  decrease  in  purchased  power  costs was
primarily due to depressed wholesale power market prices.

     The changes in  Enterprises'  operating  income (loss) for 2002 compared to
2001, included the following:

     o    lower  revenues  of $65 million  from  Exelon  Services as a result of
          reduced  construction  projects offset by lower  construction costs of
          $51 million,
     o    reductions  in  administrative   expenses  of  $28  million  primarily
          resulting from the Cost Management Initiative,
     o    reduction  of  amortization  expense  of $23  million as result of the
          discontinuance of goodwill  amortization upon the adoption of SFAS No.
          142 on January 1, 2002,
     o    accelerated   depreciation  of  assets  relating  to  Exelon  Energy's
          discontinuance of retail sales in the PJM region of $7 million,
     o    higher gross  margins at Exelon  Energy of $28 million,  which reflect
          discontinuing  retail  sales in the PJM  region and  improved  gas and
          electricity  margins.  Energy revenue  reductions of $170 million were
          more than offset by decreases in related cost of $198  million,  which
          included a favorable mark-to-market adjustment of $16 million, and
     o    higher gross margins at InfraSource of $7 million consisting of:

               o    higher  infrastructure and construction services revenues of
                    $97  million  from  an  increase  in the  electric  line  of
                    business offset by higher  infrastructure  and  construction
                    costs of $53 million, and
               o    lower  revenues of $117 million as a result of the continued
                    decline  of  the  telecommunications  industry  and  related
                    reduction   in   construction   services   offset  by  lower
                    construction costs of $80 million.

     The changes in income (loss) before income taxes for 2002 compared to 2001,
included the following:


     o    a pre-tax gain of $198 million  recorded on the AT&T Wireless  sale,
     o    lower  interest  expense of $23  million  due to pay down of debt from
          proceeds of the AT&T Wireless sale,
     o    higher equity in earnings of unconsolidated  affiliates of $16 million
          resulting  from the  discontinuance  of losses on AT&T  Wireless  as a
          result of its sale,


                                       34


     o    write-down  of  communications  investments  of  $27  million,  energy
          related investment write-downs of $14 million, and a net write-down of
          other assets of $4 million in 2002 offset by $12 million loss from net
          write-downs of communications  investments,  a $1 million loss from an
          energy related investment,  and a net write-down of other assets of $2
          million in 2001,
     o    equity in earnings from a  communications  joint venture of $9 million
          primarily  relating to its  recovery of trade  receivables  previously
          considered uncollectible, and
     o    lower interest income of $7 million.

     The  effective  income  tax rate was 50.4% for 2002  compared  to 33.3% for
2001. This increase in the effective tax rate was primarily  attributable to the
AT&T Wireless sale and tax adjustments resulting from various income tax related
items of $21  million,  partially  offset  by the  discontinuation  of  goodwill
amortization  as of  January 1, 2002,  which was not  deductible  for income tax
purposes in 2001.

     The cumulative effect of a change in accounting  principle recorded in 2002
due to the adoption of SFAS No. 142 reduced net income by $243  million,  net of
income taxes. See Note 4 of the Notes to Consolidated Financial Statements.

Year Ended December 31, 2001 Compared to Year Ended December 31, 2000

     On October 20, 2000, we became the parent  corporation of PECO and ComEd as
a result of the Merger.  Our results of  operations  for 2000  consist of PECO's
results for the entire year and ComEd's results from October 20, 2000 to the end
of the year.

Net Income and Earnings Per Share

     Our net income for 2001 increased $842 million,  or 144%, compared to 2000.
Diluted  earnings per share increased $1.56 per share, or 54%. Income before the
cumulative effect of changes in accounting principles increased $854 million, or
152%, for 2001. Diluted earnings per share on the same basis increased $1.64 per
share, or 60%.  Earnings per share increased less than net income as a result of
an increase in the weighted average shares of common stock  outstanding from the
issuance of common stock in connection with the Merger,  partially offset by the
repurchase  of common stock with the proceeds from PECO's May 2000 stranded cost
recovery securitization.

Results of Operations by Business Segment

     The remaining  sections  under this heading,  "Year Ended December 31, 2001
Compared To Year Ended  December 31, 2000,"  present the  operating  results for
each of our business  segments for 2001. All  comparisons  presented  under this
heading are comparisons of operating results and other  statistical  information
for 2001 to operating results and other statistical  information for 2000. These
results  reflect  intercompany   transactions,   which  are  eliminated  in  our
consolidated financial statements.

     The  October  20,  2000  acquisition  of  Unicom,  and the  January 1, 2001
corporate  restructuring,  significantly impacted our results of operations.  To
provide a more  meaningful  analysis  of results  of  operations,  the  business
comparisons  below identify the portion of the variance that is  attributable to
Unicom's results of operations and the portion of the variance that results from
normal  operations  attributable  to changes  in  components  of the  underlying
operations of Exelon.  The merger  variance  represents  Unicom results for 2000
prior to the  October  20,  2000  acquisition  date,  the  effect  of  excluding
Merger-related  costs from Exelon's 2000 operations and an adjustment to reflect
results as if the corporate  restructuring occurred on January 1, 2000. The 2000
pro forma effects of the Merger and


                                       35


restructuring  were  developed  using  estimates  of  various  items,  including
allocations  of  corporate  overheads  to  business  segments  and  intercompany
transactions.

     Energy Delivery's revenue net of purchased power and fuel expense,  in 2001
was comparable to that for 2000.

     The  changes in Energy  Delivery's  operating  income for 2001  compared to
2000, included the following:

     o    increased  depreciation  expense of $43 million,  primarily associated
          with capital additions,
     o    increased  regulatory  asset  amortization  of $34 million,  primarily
          attributable to additional amortization of PECO's CTCs,
     o    higher  administrative  and  general  costs as a result  of  increased
          allocation of costs previously recorded at a corporate level, and
     o    higher employee severance costs of $18 million in 2001 associated with
          the Merger.

     The  changes  in income  before  income  taxes for 2001  compared  to 2000,
included the following:

                                       36



     o    reduction of $115 million in intercompany interest income in 2001 from
          Unicom  Investments,  Inc.,
     o    gain  of  $113  million  on a  forward  share  repurchase  arrangement
          recognized during the first quarter of 2000,
     o    lower  interest  expense  due to  reductions  in the  amount  of  debt
          outstanding as well as lower interest rates due to debt refinancing,
     o    non-recurring loss of $38 million on the sale of Cotter Corporation, a
          ComEd subsidiary, recognized during the first quarter of 2000, and
     o    additional  interest on Transition  Bonds issued to securitize  PECO's
          stranded cost recovery.

     The  effective  income  tax rate was 40.8% for 2001  compared  to 41.8% for
2000.  This decrease in the effective tax rate was primarily  attributable  to a
reduction in state income tax.

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

o    Rate  Changes.  The  increase  in  revenues  attributable  to rate  changes
     reflects  the  expiration  of a 6% reduction  in PECO's  electric  rates in
     effect  for 2000  related  to PECO's  restructuring  settlement,  partially
     offset by a $60 million PECO rate  reduction  in effect for 2001,  and a 5%
     ComEd residential rate reduction,  effective  October 1, 2001,  required by
     the Illinois restructuring legislation.

                                       38


o    Customer Choice. All PECO and all ComEd  non-residential  customers had the
     choice to  purchase  energy  from  other  suppliers  throughout  2001.  The
     increase in electric retail revenues  included  increased  revenues of $276
     million from customers in Pennsylvania  who selected or returned to PECO as
     their electric generation supplier. This was partially offset by a decrease
     in revenues of $145 million from customers in Illinois electing to purchase
     energy from an ARES or from ComEd, under the PPO.
o    Weather.  The weather impact was favorable  compared to 2000 as a result of
     warmer summer  weather  conditions,  although the favorable  summer weather
     conditions were partially offset by unfavorable winter weather  conditions,
     primarily in the ComEd service territory.
o    Revenue  Taxes.  The  change  in  revenue  taxes  represents  a  change  in
     presentation of certain revenue taxes for ComEd from operating  revenue and
     tax expense to collections recorded as liabilities  resulting from Illinois
     legislation. This change in presentation does not affect income.
o    Other Effects. A strong housing  construction market in Chicago contributed
     to residential and small commercial and industrial  customer volume growth,
     partially  offset by the  unfavorable  impact of a slower  economy on large
     commercial and industrial customers.

     The reduction in Wholesale and Miscellaneous  revenues in 2001, as compared
to 2000,  reflects  lower  off-system  sales due to the  expiration of wholesale
contracts  that were  offered by ComEd from June 2000 to May 2001 to support the
open access  program in Illinois,  partially  offset by  increased  transmission
service revenue and the reversal of a $15 million reserve for revenue refunds to
ComEd's municipal customers as a result of a favorable FERC ruling.

     The changes in gas revenue for 2001, as compared to 2000, were as follows:

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

o    Rate  Changes.  The  favorable  variance  in  price is  attributable  to an
     adjustment  of the  purchased  gas cost  recovery by the PUC,  effective in
     December  2000.  The average price per million cubic feet for all customers
     for 2001 was 39% higher than 2000. PECO's gas rates are subject to periodic
     adjustments by the PUC designed to recover or refund 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.
o    Weather.  The  unfavorable  weather impact is attributable to warmer winter
     weather  conditions  in the PECO  service  territory.  Heating  degree days
     decreased 12% in 2001 compared to 2000.
o    Volume.  Exclusive  of weather  impacts,  lower  delivery  volume  affected
     revenue by $14 million  compared to 2000.  Total  volume of sales to retail
     customers  decreased 11% compared to 2000,  primarily as a result of slower
     economic conditions in 2001 offset by customer growth.

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


     The  changes  in  Generation's  revenue,  net of  purchased  power and fuel
expense, for 2001 compared to 2000, included the following:

          o    increases in wholesale market prices during the first five months
               of 2001,  particularly in the PJM and Mid-America  Interconnected
               Network  regions,  which  were  primarily  driven by  significant
               increases in fossil fuel prices,
          o    higher  revenues  in 2001  due to the  inclusion  of  charges  to
               affiliates  for line losses  which were not included in pro forma
               2000 revenue,
          o    mark-to-market   gains  of  $16   million   and  $14  million  on
               non-trading and trading energy contracts, respectively, offset by
               realized trading losses of $6 million in 2001, and
          o    higher  nuclear  plant output due to increased  capacity  factors
               during 2001.

     The large  concentration  of nuclear  generation in Generation's  portfolio
allowed  it to  capture  higher  margins  in the  wholesale  market for sales to
non-affiliates due to minimal increases in fuel costs.

     The changes in  operating  income for 2001  compared to 2000,  included the
following:

          o    reductions in the number of employees,
          o    fewer nuclear outages in 2001 than in 2000,
          o    increased  decommissioning expense of $140 million reflecting the
               discontinuance  of  regulatory  accounting  practices for certain
               nuclear generating stations,
          o    net realized losses on  decommissioning  trust investments during
               2001 of $60 million, and
          o    additional reserves related to litigation of $30 million.

     Other items decreasing net income were an increase in equity in earnings of
AmerGen  and  Sithe of $90  million  as a result of  acquisitions  in 2000 and a
reduction  in   depreciation   and   decommissioning   expense  of  $90  million
attributable  to the  extension  of  estimated  service  lives  of  Generation's
generating plants.

     The  effective  income  tax rate was 39.0% for 2001  compared  to 38.1% for
2000. This increase in the effective tax rate was primarily  attributable to the
change in the amortization of investment tax credits.  The investment tax credit
amortization period was extended as a result of 2001 plant life extensions.

     The cumulative effect of a change in accounting  principle recorded in 2001
was income of $12 million,  net of income taxes, related to the adoption of SFAS
No. 133.

                                       40


     For 2001, Generation's sales were 201,879 GWhs,  approximately 60% of which
were to affiliates. Supply sources were as follows:

- ------------------------------------------------------------------------------
Nuclear units                                                              54%
Purchases                                                                  37%
Fossil and hydro units                                                      3%
Generation investments                                                      6%

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

     Generation's  nuclear  fleet,  including  AmerGen,  performed at a weighted
average   capacity  factor  of  94.4%  for  2001  compared  to  93.8%  in  2000.
Generation's  nuclear fleet's production costs,  including AmerGen,  were $12.78
per MWh for 2001, compared to $14.64 per MWh for 2000.

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


         The changes in Enterprises'  operating  income (loss) for 2001 compared
to 2000, included the following:

          o    Exelon Energy discontinuing retail sales in the PJM region, which
               resulted  in lower power  costs of $193  million  offset by lower
               retail energy sales of $166 million,
          o    acquisitions  by Exelon  Services  and  InfraSource  resulted  in
               increased   infrastructure  and  construction  revenues  of  $574
               million offset by increased related costs of $554 million,
          o    increased depreciation and amortization expense of $26 million as
               a result of goodwill amortization related to acquisitions made by
               Exelon Services and InfraSource, and
          o    higher  construction costs of $32 million from Exelon Services as
               a result  of  increased  construction  projects  offset by higher
               construction revenues of $26 million.

     The changes in income (loss) before income taxes for 2001 compared to 2000,
included the following:

          o    net realized gains on investments of $27 million,
          o    higher  equity in earnings of  unconsolidated  affiliates  of $23
               million from lower net losses in communications joint ventures,
          o    reduced losses of $21 million from sale of assets in 2000, and
          o    net write-downs on investments of $13 million.

     The  effective  income  tax rate was 33.6% for 2001  compared  to 35.6% for
2000.  This decrease in the effective  tax rate was  primarily  attributable  to
higher book  write-downs of  investments in 2001,  which were not deductible for
income tax purposes.


Liquidity and Capital Resources

Our businesses are capital intensive and require considerable capital resources.
These  capital  resources are primarily  provided by internally  generated  cash
flows from Energy  Delivery's and


                                       41


Generation's  operations.  When necessary, we obtain funds from external sources
in the  capital  markets  and through  bank  borrowings.  Our access to external
financing  at  reasonable  terms  depends  on our and our  subsidiaries'  credit
ratings and general business conditions, as well as that of the utility industry
in general. If these conditions deteriorate to where we no longer have access to
external financing sources at reasonable terms, we have access to a $1.5 billion
revolving  credit facility which we currently  utilize to support our commercial
paper program.  See the Credit Issues section of Liquidity and Capital Resources
for further  discussion.  We  primarily  use our capital  resources  to fund our
capital requirements,  including  construction,  investments in new and existing
ventures,  to repay  maturing  debt and to pay common  stock  dividends.  Future
acquisitions that we may undertake may require external  financing,  which might
include our issuing common stock.

Cash Flows from Operating Activities

     Cash flows provided by 2002  operations  were  consistent with 2001 at $3.6
billion.  Energy  Delivery and Generation  provided  approximately  70% and 30%,
respectively,  of the 2002 cash flows, while  Enterprises'  contribution was not
significant.  Energy Delivery's cash flows from operating  activities  primarily
result from sales of electricity  and gas to a stable and diverse base of retail
customers and are weighted toward the third quarter.  Energy  Delivery'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.
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 flows 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 prices. Although the amounts
may vary from  period to period  as a result of the  uncertainties  inherent  in
business, we expect that Energy Delivery and Generation will continue to provide
a reliable  and steady  source of  internal  cash flow from  operations  for the
foreseeable  future.  In the  fourth  quarter of 2002,  we made a  discretionary
tax-deductible  pension  plan  contribution  of $150  million  funded  by ComEd,
Generation and BSC. We also expect to make a discretionary  plan contribution in
2003 of $300 million to $350 million.

Cash Flows from Investing Activities

Cash flows used in investing  activities  for 2002 were $2.5  billion,  of which
$2.2  billion was used for  capital  expenditures,  compared to $2.4  billion in
2001,  of  which  $2.1  billion  was used for  capital  expenditures.  Investing
activities in 2002 also includes $445 million for the  acquisition of generating
plants.

     Capital expenditures by business segment for 2002 and projected amounts for
2003 are as follows:

     Energy  Delivery's  estimated  capital  expenditures  for 2003  reflect the
continuation of efforts to improve the reliability of its  distribution  system.
Approximately  35% of the  budgeted  2003  expenditures  are for  growth and the
remainder are for additions to or upgrades of existing facilities. We anticipate
that


                                       42


Energy Delivery will obtain financing, when necessary,  through borrowings,
the  issuance by PECO or ComEd,  or both,  of  preferred  securities  or capital
contributions made by us.

     Generation  purchased two natural-gas and oil-fired  generating plants from
TXU on April 25,  2002.  The $443 million  purchase  was funded with  commercial
paper,  which  Exelon  issued and  Generation  is repaying  from cash flows from
operations. The balance of Generation short-term borrowings at December 31, 2002
attributable  to the TXU  purchase  was  approximately  $70  million.  Investing
activities  also  include  a $2  million  use of cash for the  November  1, 2002
purchase of Sithe New England.  The $2 million use is net of $12 million of cash
acquired. The remainder of the purchase was financed with a $534 million note to
Sithe.  In  2002,  Generation  agreed  to make a loan to  AmerGen  of up to $100
million,  at an interest rate of one-month LIBOR plus 2.25%, and with a maturity
date of July 1,  2003.  As of  December  31,  2002,  the  balance of the loan to
AmerGen was $35 million.

     We project that  Generation's  capital  expenditures  in 2003 will be lower
than they were in 2002, and the majority of these  expenditures will be used for
additions  and upgrades to existing  facilities,  nuclear fuel and  increases in
capacity at existing  plants.  Eight nuclear  refueling  outages are planned for
2003, compared to 11 during 2002. We project that the total capital expenditures
for nuclear  refueling  outages will  decrease in 2003 over 2002 by $10 million.
Generation  has agreed to make  capital  contributions  to AmerGen of 50% of the
purchase  price of any  acquisitions  that AmerGen  makes.  We  anticipate  that
Generation's  capital expenditures will be funded by internally generated funds,
Generation's borrowings or capital contributions from us.

     Enterprises'  capital  expenditures were $44 million in 2002.  Enterprises'
capital  expenditures  for 2002 were  primarily  for additions to or upgrades of
existing facilities. On April 1, 2002, Enterprises sold its 49% interest in AT&T
Wireless for $285 million in cash.

     We  project  that  Enterprises'  capital  expenditures  for  2003  will  be
approximately  $26 million,  primarily  for additions to or upgrades of existing
facilities.  We anticipate that all of Enterprises' capital expenditures will be
funded by internally generated funds,  capital  contributions or borrowings from
us.

     Our total estimated  capital  expenditures in 2003 are  approximately  $2.0
billion. Internally generated cash flow is expected to meet capital requirements
excluding acquisitions.  Our 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  were $1.1  billion in 2002,  as
compared to $1.3 billion in 2001, due to lower dividend payments, a contribution
from a minority  interest,  and increased employee stock purchase plan activity.
The primary components of 2002 financing activity are as follows:

     o    ComEd  issued  $700  million  of First  Mortgage  Bonds and  pollution
          control  bonds to redeem  $700  million  of First  Mortgage  Bonds and
          pollution  control bonds.  ComEd also paid at maturity $500 million of
          First Mortgage Bonds and other long-term debt, retired $340 million of
          transitional  trust  notes and had net  issuances  of $123  million of
          commercial paper.

     o    PECO issued $225 million of First and Refunding  Mortgage  Bonds.  The
          proceeds  of these bonds were used to repay  commercial  paper that it
          used to pay at maturity $222 million of First and  Refunding  Mortgage
          Bonds.  PECO made  principal  payments of $326  million on  transition
          bonds and net issuances of $200 million of commercial paper.

                                       43


     On January 22,  2003,  ComEd  issued $350  million of 3.70% First  Mortgage
Bonds,  due on February 1, 2008 and $350 million of 5.875% First Mortgage Bonds,
due on February 1, 2033.  These bond proceeds  were used to refinance  long-term
debt that had been retired during the third and fourth quarters of 2002.

     The 2001 common stock  dividend  payments of $583 million  cover the period
from October 20, 2000, the date of the Merger, through the end of 2001. The 2002
cash dividend  payments on common stock were $563 million.  On January 28, 2003,
our  Board of  Directors  declared  a  quarterly  dividend  of $0.46  per  share
representing an annual dividend rate of $1.84 per share, which is an increase of
$0.08 per share over 2002. We intend to grow our dividend over time at a rate of
approximately 4% to 5%, commensurate with long-term earnings growth. The payment
of future  dividends  is subject to  approval  and  declaration  by the Board of
Directors each quarter.

     Financing  activities  in 2002  exclude  the  non-cash  issuance  of a $534
million note to Sithe for the November 1, 2002  acquisition of Sithe New England
and  approximately  $1.0 billion of Sithe New England  long-term debt,  which is
reflected in our Consolidated Balance Sheets as of December 31, 2002.

Credit Issues

     We  meet  our  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 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  Corporate  may increase or decrease the sublimits of
each of the participants upon written  notification to the banks. As of December
31,  2002,  Exelon  Corporate's  sublimit  was $900  million,  ComEd's  was $200
million,  PECO's was $400 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  December  31,  2002,  our
Consolidated  Balance  Sheet  reflects  the $948  million  of  commercial  paper
outstanding, of which $267 million was classified as long-term debt.

     For 2002,  the average  interest  rate on notes  payable was  approximately
1.88%.  Certain of the credit agreements to which Exelon Corporate,  ComEd, PECO
and  Generation are parties  require them 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  attributed  to
securitization  debt,  certain  changes in  working  capital,  distributions  on
preferred  securities of  subsidiaries  and in the case of Exelon  Corporate and
Generation,  interest on Sithe New England's debt.  Exelon Corporate is measured
at the Exelon  consolidated  level. The following table summarizes the threshold
reflected  in the credit  agreement  that the ratio  cannot be less than for the
twelve-month period ended December 31, 2002:

                                                    Credit Agreement Threshold

Exelon Corporate                                                     2.65 to 1
ComEd                                                                2.25 to 2
PECO                                                                 2.25 to 1
Generation                                                           3.25 to 1
- ------------------------------------------------------------------------------


     At December  31,  2002,  we were in  compliance  with the credit  agreement
thresholds.


                                       44


     At December 31, 2002, our capital  structure  consisted of 60% of long-term
debt,  32% common  equity,  5% notes  payable  and 3%  preferred  securities  of
subsidiaries.   Total  debt  included  $6.2  billion  of   securitization   debt
constituting  obligations  of certain  consolidated  special  purpose  entities,
representing 26% of capitalization.  These consolidated special purpose entities
were  created for the sole  purpose of issuing debt  obligations  to  securitize
intangible  transition  property  and  CTC's of Energy  Delivery.  Shareholders'
equity  was  reduced by $1  billion  in 2002 due to the  recording  of a minimum
pension liability.

     To provide an additional short-term borrowing option that will generally be
more  favorable  to  the  borrowing  participants  than  the  cost  of  external
financing, we operate an intercompany  utility-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 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. There were no material money pool transactions in 2002.

     Our access to the capital  markets,  including the commercial paper market,
and our financing costs in those markets depend on the securities ratings of the
entity that is accessing the capital markets. None of our borrowings are 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 our
$1.5 billion credit facility, and certain other credit facilities.  From time to
time,  we enter 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. The following table shows our securities ratings at December 31, 2002:

     A security rating is not a  recommendation  to buy, sell or hold securities
and may be subject to revision or withdrawal at any time by the assigning rating
agency.

     We obtained an order from the 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 December 31, 2002, there was $1.8 billion of financing
authority  remaining  under the SEC order.  Our  request  for an  additional  $4
billion in financing  authorization  is pending with the SEC. The current  order
limits our  short-term  debt  outstanding  to $3 billion of the $4 billion total
financing authority.  Our request that the short-term debt sub-limit restriction
be eliminated is pending with the SEC. The SEC order also authorized us to issue


                                       45


guarantees  of up to $4.5 billion  outstanding  at any one time. At December 31,
2002,   Exelon  had  provided  $1.5  billion  of  guarantees.   See  Contractual
Obligations,  Commercial  Commitments and Off Balance Sheet  Obligations in this
section for  further  discussion  of  guarantees.  The SEC order  requires us to
maintain  a  ratio  of  common   equity  to  total   capitalization   (including
securitization  debt) on and after  June 30,  2002 of not less than 30%.  Exelon
expects that it 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 us, to the extent we receive  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 December  31,  2002,  Exelon had
retained  earnings of $2.0 billion,  including ComEd's retained earnings of $577
million, PECO's retained earnings of $401 million and Generation's undistributed
earnings of $924 million. We are 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 December 31, 2002, we had invested $2.1
billion in EWGs,  leaving $1.9 billion of investment  authority under the order.
Our request for an additional  $1.5 billion in EWG investment  authorization  is
pending with the SEC.

     During  2001,  we loaned  $150  million to Sithe.  Sithe paid $2 million in
interest on this loan and fully repaid the principal balance in December of 2001
from the proceeds of a bank  borrowing.  In connection  with a bank borrowing by
Sithe,  we provided the lenders with a support letter  confirming our investment
in Sithe and agreeing to maintain a positive net worth in Sithe.  We expect that
Sithe's  net  worth  will  remain  positive  for  the  foreseeable  future  and,
accordingly,  this  agreement  is not  reflected  in the  following  Contractual
Obligations,   Commercial   Commitments   and  Off  Balance  Sheet   Obligations
discussion. This agreement does not guarantee any debt or obligation of Sithe.

     We have a long-term supply  agreement  through December 2022 with Distrigas
to guarantee  physical gas supply to our New England generating units. Under the
agreement, prices are indexed to New England gas markets.

     Generation has an obligation to decommission its nuclear power plants.  Our
current  estimate  of  decommissioning  costs for the  nuclear  plants  owned by
Generation   is  $7.4   billion  in  current   year  (2003)   dollars.   Nuclear
decommissioning activity occurs primarily after a plant is retired. Based on the
extended license lives of our nuclear plants, we will begin  decommissioning our
plants from 2014 through 2056, with  expenditures  primarily  occurring when our
operating plants are  decommissioned,  during the period from 2029 through 2056.
At December 31, 2002, the  decommissioning  liability,  which is recognized over
the life of the  plant,  was  recorded  in our  Consolidated  Balance  Sheets as
Accumulated  Depreciation  and  Deferred  Credits and Other  Liabilities  in the
amounts  of  $2.8  billion  and  $1.4  billion,  respectively.  To  fund  future
decommissioning  costs,  Generation  held $3.1 billion of  investments  in trust
funds, including net unrealized gains and losses, at December 31, 2002.

     Our  commercial   commitments   as  of  December  31,  2002,   representing
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 our obligations, are as follows:

     Sithe Boston  Generation  Project Debt. We  participate  in a $1.25 billion
credit facility, most of which is available to finance the construction projects
of Sithe Boston Generating,  LLC (the SBG Facility).  The outstanding balance of
this facility at December 31, 2002 was $1.0 billion.  The SBG Facility  provides
that if these construction  projects are not completed by June 12, 2003, the SBG
Facility lenders will have the right, but will not be required,  to, among other
things,  declare all amounts  then  outstanding  under the SBG  Facility and the
interest  rate  swap  agreements  to  be  due.   Generation  believes  that  the
construction  projects will be substantially  complete by May 31, 2003, but that
all of the approvals  required  under the SBG Facility may not be issued by that
date.  Generation is currently  evaluating  whether the  requirements of the SBG
Facility  relating to the  construction  projects  can be  satisfied by June 12,
2003.  In the event that the  requirements  are not  expected to be satisfied by
June 12, 2003,  Generation will contact the SBG Facility  lenders  concerning an
amendment  or  waiver  of  these  provisions  of the  SBG  Facility.  Generation
currently  expects  that  arrangements  for  such an  amendment  or  waiver,  if
necessary, can be successfully negotiated with the SBG Facility lenders.

     Unconsolidated Equity Investments. Generation is a 49.9% owner of Sithe and
accounts for the investment as an unconsolidated  equity  investment.  The Sithe
New  England  purchase  did not  affect  the  accounting  for Sithe as an equity
investment.  Separate  from the Sithe New  England  transaction,  Generation  is
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. At
the end of this exercise  period,  which is December 2005, if Generation has not
exercised its Call option and the other  stockholders  have not exercised  their
Put  rights,  Generation  will have an  additional  one-time  option to purchase
shares from the other stockholders to bring Generation's ownership in Sithe from
the current 49.9% to 50.1% of Sithe's total outstanding common stock.

     The  PCA  originally   provided  that  the  Put  and  Call  options  became
exercisable as of December 18, 2002 and expired 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,  the put price of approximately
$460 million, growing at a market rate of interest, 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.

     The delay in the effective  date of Apollo's Put right allows us to explore
a  further   restructuring  of  our  investment  in  Sithe.  We  are  continuing
discussions with Apollo and Marubeni regarding  restructuring  alternatives that
are designed in part to resolve our ownership  limitations of Sithe's qualifying
facilities. We would hope to implement any additional restructuring of our Sithe
investment  in


                                       48


2003. If we are unsuccessful in  restructuring  the Sithe  transaction,  we will
proceed  to  implement  measures  to  address  the  ownership  of the  qualified
facilities  as well as divest  non-strategic  assets, for  which  the  financial
outcome is uncertain.

     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  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 our financial  results may include Sithe's
financial  results  from the date of purchase.  At December 31, 2002,  Sithe had
total assets of $2.6 billion and total debt of $1.3  billion.  This $1.3 billion
includes  $624  million of  subsidiary  debt  incurred  primarily to finance the
construction  of six new  generating  facilities,  $461 million of  subordinated
debt, $103 million of line of credit borrowings,  $43 million of current portion
of  long-term  debt and  capital  leases,  $30  million of capital  leases,  and
excludes  $453  million of  non-recourse  project debt  associated  with Sithe's
equity investments.  For the year ended December 31, 2002, Sithe had revenues of
$1.0  billion.  As of December 31, 2002,  Generation  had a $478 million  equity
investment in Sithe.

     Additionally,   the  debt  on  the  books  of  our  unconsolidated   equity
investments  and joint  ventures is not  reflected on our  Consolidated  Balance
Sheets.  We estimate that this debt,  including the $1.3 billion of Sithe's debt
described in the preceding paragraph, totals approximately $1.3 billion and that
our portion of that amount,  based on our ownership interest in the investments,
is approximately $673 million.

     Generation's  equity investment in AmerGen was $160 million and $95 million
at December 31, 2002 and 2001,  respectively.  Generation and British Energy plc
(British  Energy),  Generation's  joint  venture  partner in AmerGen,  have each
agreed to provide up to $100 million to AmerGen at any time that the  Management
Committee of AmerGen  determines that, in order to protect the public health and
safety and/or to comply with NRC requirements, these funds are necessary to meet
ongoing operating  expenses or to safely maintain any AmerGen plant. The current
financial  condition  of British  Energy  has been the focus of media  attention
recently.  We cannot  predict the ability of British  Energy to provide funds to
AmerGen.  However,  we do not  believe  this will  impact  AmerGen's  ability to
conduct its business.

     PECO Accounts  Receivable  Agreement.  PECO is party to an agreement with a
financial  institution under which it can sell an undivided  interest,  adjusted
daily, in up to $225 million of designated  accounts  receivable  until November
2005.  PECO entered into this  agreement  to  diversify  its funding  sources at
favorable  floating  interest  rates. At December 31, 2002, PECO had sold a $225
million interest in accounts receivable,  consisting of an $164 million interest
in accounts  receivable,  which we  accounted  for as a sale under SFAS No. 140,
"Accounting for Transfers and Servicing of Financial  Assets and  Extinguishment
of  Liabilities  - a Replacement  of FASB  Statement No. 125," and a $61 million
interest in special agreement accounts  receivable,  which we accounted for as a
long-term note payable. PECO must continue to service these receivables and must
maintain the level of the accounts  receivable at $225 million. If PECO fails to
maintain  that level,  the cash that would  otherwise  be received by PECO under
this program must be held in escrow until the level is met. At December 31, 2002
and 2001, PECO met this requirement.

     Insurance Coverage. We carry property damage, decontamination and premature
decommissioning  insurance  for each station loss  resulting  from damage to its
nuclear plants.  Additionally,  through our subsidiaries,  we are a member of an
industry mutual insurance company that provides replacement power cost insurance
in the event of a major  accidental  outage at a nuclear  station.  Finally,  we
participate  in the American  Nuclear  Insurers  Master  Worker  Program,  which
provides



                                       49


coverage  for worker tort  claims  filed for bodily  injury  caused by a nuclear
energy accident.  See Note 19 of the Notes to Consolidated  Financial Statements
for further discussion of nuclear insurance.

Critical Accounting Estimates

     The  preparation  of financial  statements  in  conformity  with  Generally
Accepted  Accounting   Principles  requires  that  management  apply  accounting
policies and make  estimates and  assumptions  that affect results of operations
and the amounts of assets and liabilities reported in the financial  statements.
Management  discusses these  estimates and  assumptions  with its Accounting and
Disclosure Governance Committee on a regular basis and provides periodic updates
to the  Audit  Committee  of the Board of  Directors  on  management  decisions.
Management  believes that the following  areas  require  significant  management
judgment  in making  estimates  and  assumptions  to describe  matters  that are
inherently uncertain and that may change in subsequent periods.

Accounting for Derivative Instruments
     We use derivative financial instruments primarily to manage commodity price
and interest rate risks. In connection  with our Risk  Management  Policy (RMP),
we:

     o    use  financial  derivatives  to manage our  exposure to interest  rate
          fluctuations related to our variable rate debt instruments, changes in
          interest rates related to planned future debt issuances prior to their
          actual  issuance  and  changes in the fair value of  outstanding  debt
          which we are planning to retire early,

     o    enter into  derivatives  to manage the  physical and  financial  risks
          associated with our energy supply and load obligations, and

     o    enter into  energy  related  derivatives  for  trading or  speculative
          purposes.

     Our derivative  activities are subject to the  management,  direction,  and
control  of our  Risk  Management  Committee  (RMC).  The RMC  sets  forth  risk
management  philosophy and objectives,  and establishes  procedures for control,
valuation, counterparty credit approval, and the monitoring and reporting of our
activities  in  derivative   markets  and  the  performance  of  our  derivative
contracts.

     We make estimates and assumptions  concerning future commodity prices, load
requirements,  interest  rates,  the  timing  of future  transactions  and their
probable  cash flows,  the fair value of  contracts  and the changes in the fair
value  we  expect  in  deciding   whether  or  not  to  enter  into   derivative
transactions, and in determining the initial accounting treatment for derivative
transactions.

     We account for derivative financial  instruments under SFAS No. 133. To the
extent  that  changes in SFAS No. 133 modify  current  guidance,  including  the
standards  for  determining  whether  contracts  can be accounted  for as normal
purchases and normal sales, the accounting treatment for derivatives may change.

     We are required under SFAS No. 133 to record derivative instruments at fair
value. Depending on the designation of the derivative,  the fair value is either
recorded in the income statement or as a component of other comprehensive income
in shareholders'  equity (OCI). We use quoted exchange prices to the extent they
are available or external  broker quotes in order to determine the fair value of
energy contracts. When external prices are not available, we use internal models
to determine the fair value.  These internal  models include  assumptions of the
future prices of energy based on the specific  energy market the energy is being
purchased in using  externally  available  forward market pricing curves for all
periods  possible  under the pricing  model.  We use the Black model, a standard
industry  valuation  model,  to  determine  the fair value of energy  derivative
contracts  that  are  marked-to-market.  To  determine  the  fair  value  of our
outstanding  interest  rate swap  agreements  we use external  broker  quotes or
calculate


                                       50


the fair value  internally  using the Bloomberg swap valuation  tool.  This tool
uses the most recent market inputs and a widely accepted valuation methodology.

     During 2002,  Generation recognized unrealized and realized net gains of $6
million and $20 million, respectively, relating to mark-to-market adjustments of
certain  non-trading power purchase and sale contracts  pursuant to SFAS No. 133
and unrealized  and realized net losses  aggregating $9 million and $20 million,
respectively,  relating to mark-to-market  adjustments of derivative instruments
entered into for trading purposes.

     Hedge Accounting.  As part of our energy marketing business,  we enter into
contracts to purchase or sell  electricity,  gas and ancillary  products such as
transmission rights, congestion credits and emission allowances, using contracts
that are considered derivatives under SFAS No. 133. Certain of these derivatives
qualify as hedge transactions.

     A derivative instrument can be designated as a hedge of the fair value of a
recognized asset or liability or of an unrecognized  firm commitment (fair value
hedge) or a hedge of a forecasted  transaction or the  variability of cash flows
to be received or paid  related to a recognized  asset or  liability  (cash flow
hedge).  To  qualify  for  hedge  accounting,  the  fair  value  changes  in the
derivative  must be expected to offset  80%-120% of the changes in fair value or
cash flows of the hedged item. Changes in the fair value of a derivative that is
designated  and qualifies as a fair value hedge and is highly  effective,  along
with the gain or loss on the hedged asset or liability that is  attributable  to
the  hedged  risk,  are  recorded  in  earnings.  Changes in the fair value of a
derivative  that is  designated  as and  qualifies  as a cash flow  hedge and is
highly  effective,  are  recorded in OCI,  until  earnings  are  affected by the
variability of cash flows being hedged.  Exelon continually  assesses these cash
flow  hedges  to  determine  if they  continue  to be  effective  and  that  the
forecasted  future  transaction  is  probable.  At the  point  in time  that the
contract does not meet the effective or probable criteria of SFAS No. 133, hedge
accounting  is  discontinued  and the fair value of the  derivative  is recorded
through earnings.

     Energy Contracts. We enter into contracts designated as cash flow hedges in
which we manage the  variability  of our cash flows  related to the  purchase or
sale of energy.  At the initiation of the contract the contract is identified as
a cash flow hedge,  which  requires us to  determine  whether the contract is in
accordance with our RMP, that the forecasted future transaction is probable, and
that the hedging  relationship  between  the energy  contract  and the  expected
future  purchase  or sale of energy is expected  to be highly  effective  at the
initiation of the hedge and throughout the hedging relationship. Internal models
that  measure  the  statistical  correlation  between  the  derivative  and  the
associated  hedged  item  determine  the  effectiveness  of an  energy  contract
designated  as a hedge.  An example of a contract  that would  qualify for hedge
accounting would be a forward  over-the-counter  sales contract used to hedge an
expected sale of generation exposed to market prices.

     Interest  Rate  Derivative  Instruments.  We enter into  interest rate swap
contracts  related  to  variable  rate  debt in order to  convert  the  variable
interest payments into fixed interest payments to manage the variability of cash
flows. Additionally, we enter into forward starting interest rate swaps in order
to lock in an interest  rate at a future date in  anticipation  of a future debt
issuance to manage the variability of changes in interest rates between the date
of the decision to issue and the actual date of issue.

     We also enter into interest rate swap contracts  related to fixed rate debt
in order to maintain our targeted percentage of variable rate debt.

                                       51


     The fair value of derivatives generally reflects the estimated amounts that
we would  receive or pay to terminate  the  contracts at the balance sheet date,
thereby  taking  into  account the  current  unrealized  gains or losses of open
contracts.

     Normal  Purchases  and  Normal  Sales  Exemption.  As  part  of our  energy
marketing business, we enter into contracts to purchase or sell electricity, gas
and  ancillary  products such as  transmission  rights,  congestion  credits and
emission  allowances using contracts that are considered  derivatives under SFAS
No.  133.  The  majority  of these  contracts,  however,  qualify for the normal
purchases and normal sales SFAS No. 133 exemption from mark-to-market accounting
treatment  as  they  are  for the  purchase  and  sale  of  energy  to meet  the
requirements of our customers.  These contracts include short-term and long-term
commitments  to  purchase  and sell  energy and energy  related  products in the
retail and  wholesale  markets  with the  intent and  ability to deliver or take
delivery in quantities we expect to use or sell over a reasonable  period in the
normal course of business.

     These  contracts are reflected in the financial  statements at the lower of
cost or market, on a portfolio basis, using the accrual method of accounting. We
did not have any loss contracts as of December 31, 2002.  Under these  contracts
we  recognize  any  gains or losses  when the  underlying  physical  transaction
affects earnings.  At the initiation of the contract, we make a determination as
to whether or not the contract meets the criteria as a normal purchase or normal
sale.  An example of an energy  contract  that would qualify for the normal sale
exemption  would include a forward sale contract under which we expect to supply
the full requirements of the  counterparty.  An example of a contract that would
qualify for the normal purchase  exemption would be an energy capacity  contract
that we enter into to satisfy the needs of our customer  base,  either retail or
wholesale.

     The  availability  of the normal  purchases  and normal sales  exemption to
specific  contracts  is based on a  determination  that at certain  times excess
generation is available for a forward sale and, similarly,  a determination that
at certain times  generation  supply will be insufficient to serve our load. The
determination  of the ability and intent to deliver or take delivery is based on
internal  models that forecast  customer demand and  electricity  supply.  These
models  include  assumptions  regarding  customer load growth  rates,  which are
influenced  by the  economy,  weather  and the impact of  customer  choice,  and
generating unit  availability,  particularly  nuclear generating unit capability
factors.  Significant  changes in these  assumptions  could  result in contracts
being considered differently under SFAS No. 133 and the potential requirement of
mark-to-market accounting.

     Proprietary Trading. As part of our energy trading operation, we enter into
contracts  to buy and sell  energy for trading  purposes.  These  contracts  are
recognized  on the balance sheet at fair value and changes in the fair value are
recognized through earnings. All proprietary trading activity is recorded net in
revenue.  Trading  activities are a very small portion of Exelon's overall power
marketing  activities.  The  trading  portfolio  is  subject to  stringent  risk
management  limits and policies,  including  volumetric and depression limits to
manage exposure to market risk, as prescribed by the RMC.

     Non-Trading  Contracts.  To manage our commodity risk exposure and meet our
load requirements,  we have also entered into non-trading  contracts that do not
meet the definition in SFAS No. 133 of a normal  purchase or normal sale or meet
the requirements for hedge accounting treatment. These non-trading contracts are
marked-to-market  when the underlying  item affects  earnings with the gains and
losses recorded in Purchased Power and Fuel expense.  Non-trading  contracts are
subject to stringent risk management  limits and policies,  as prescribed by the
RMC.

     Although we use  derivative  instruments  to assist in  managing  commodity
price and interest rate risks, we can still experience  earnings volatility from
period to period  because of the risks  associated  with  marketing  and trading
electricity and other energy-related products.

Regulatory Assets and Liabilities
     Energy Delivery's operating subsidiaries,  ComEd and PECO, are regulated by
their respective state regulatory commissions as well as by FERC. The regulators
in Illinois and Pennsylvania, as well as FERC, use cost-based rate structures to
determine the rates we will charge customers.  In establishing cost-based rates,
the ICC and the PUC may consider the capital  requirements  and working  capital
needs to operate the  distribution  and  transmission  business,  determine  the
operating  cost  levels  that can be passed on to  customers  and  provide for a
reasonable return to our shareholders.  In their determination of rates, the ICC
and PUC may include  allowable  costs in periods other than the periods in which
an  unregulated  entity  would record the costs in the income  statement.  These
costs are  accounted for as either a regulatory  asset or liability.  Regulatory
assets  represent  costs that have been  deferred to future  periods  when it is
probable  that the  regulator  will allow for recovery  through rates charged to
customers.  Regulatory liabilities represent revenues received from customers to
fund  expected  costs  that have not yet been  incurred.  Regulatory  assets and
liabilities are accounted for under SFAS No. 71,  "Accounting for the Effects of
Certain Types of Regulation"  (SFAS No. 71). Use of SFAS No. 71 is applicable to
our utility  operations  that meet the following  criteria:  the  operations are
subject to third-party  regulation of rates;  the rates are cost-based;  and the
assumption  that all costs will be recoverable  from customers  through rates is
appropriate  and  reasonable.  If a separable  portion of our business no longer
meets these  criteria,  we are required to  eliminate  the  financial  statement
effects of regulation for that part of our business.

     Both ComEd and PECO are currently subject to rate freezes or rate caps that
limit the opportunity to recover increased costs and the costs of new investment
in facilities  through rates during the rate freeze or rate cap period.  Current
rates include the recovery of our existing regulatory assets.

     The most significant regulatory assets we have recorded are:

     o    Competitive   Transition  Charges:   These  charges  represent  PECO's
          stranded  costs  that  the  PUC  determined  would  be  allowed  to be
          recoverable  through  regulated rates.  These costs are related to the
          deregulation  of  the  generation  portion  of  the  electric  utility
          business in Pennsylvania.  The unamortized  balance of the CTC of $4.6
          billion  and  $4.9   billion  as  of  December   31,  2002  and  2001,
          respectively, was recorded on our Consolidated Balance Sheets. The CTC
          includes Intangible Transition Property sold to PECO Energy Transition
          Trust,  a wholly owned  subsidiary  of PECO,  in  connection  with the
          securitization  of PECO's  stranded cost  recovery.  These charges are
          being amortized through December 31, 2010 with a rate of return on the
          unamortized balance of 10.75%.

     o    Recoverable  Transition Costs: These charges,  related to the recovery
          of  ComEd's  former  generating  plants,  are  amortized  based on the
          expected  return on equity of ComEd in any given year. At December 31,
          2002 and 2001, we had $175 million and $277 million,  respectively, in
          recoverable  transition  costs  recorded in our  Consolidated  Balance
          Sheets.  ComEd expects to fully recover and amortize  these charges by
          the end of 2006, but may increase or decrease its annual  amortization
          to  maintain   its  earnings   within  the  earnings  cap   provisions
          established  by  Illinois  legislation.  See  Note 5 of the  Notes  to
          Consolidated   Financial  Statements  for  discussion  of  recoverable
          transition cost amortization.

     o    Recoverable   Deferred   Income  Taxes:   These  costs  represent  the
          difference  between the method in which the  regulator  allows for the
          recovery  of income  taxes and how income  taxes  would be recorded by
          unregulated   entities.   These  recoverable  deferred  income  taxes,
          recorded  in  compliance  with SFAS No.  109  "Accounting  for  Income
          Taxes," include the deferred tax effects  associated  principally with
          liberalized   depreciation   accounted  for  in  accordance  with  the
          ratemaking policies of the ICC and PUC, as well as the revenue impacts
          thereon, and assume continued recovery of these costs in future


                                       53


          rates.  At December  31, 2002 and 2001,  we had $661  million and $701
          million,  respectively,  in recoverable deferred income taxes recorded
          in our Consolidated Balance Sheets.

     o    Nuclear   Decommissioning   Costs  for  Retired  Plants:  These  costs
          represent the amount of future nuclear  decommissioning  costs related
          to the retired former ComEd plants which are being  recovered  through
          rates.  At December  31, 2002 and 2001,  we had $248  million and $310
          million,  respectively,  in nuclear  decommissioning costs for retired
          plants recorded in our Consolidated  Balance Sheets.  These costs will
          be  recovered  in rates  and  amortized  on a  straight-line  basis to
          earnings by the end of 2006.

     For each regulatory  jurisdiction where we conduct business, we continually
assess whether the regulatory  assets continue to meet the criteria for probable
future  recovery.  This  assessment  includes  consideration  of factors such as
changes in  applicable  regulatory  environments,  recent  rate  orders to other
regulated  entities  in the same  jurisdiction,  the  status of any  pending  or
potential  deregulation  legislation  and the ability to recover  costs  through
regulated  rates. If future recovery of costs ceases to be probable,  the assets
and liabilities  would be recognized in current period earnings.  A write-off of
regulatory assets could impact our ability to pay dividends under PUHCA.

     Because  our current  rates  include  the  recovery of existing  regulatory
assets and  liabilities,  and rates in effect during the rate freeze or rate cap
periods are expected to allow us to earn a reasonable rate of return during that
period,  management  believes the existing regulatory assets and liabilities are
probable of recovery.  This  determination  reflects the current  political  and
regulatory climate in the states where we do business,  but is subject to change
in the future.

Nuclear Decommissioning
     We  currently  have  direct  ownership   interests  in  16  active  nuclear
generating units and four retired nuclear generating units. In addition,  we own
a 50% equity interest in AmerGen, which operates three active nuclear generating
units.

     In connection with the operation of our nuclear units,  the NRC requires us
to decommission  these facilities  after their NRC operating  license lives end,
generally  40 years  from  the  date of  initial  operation.  We have,  however,
requested or are in the process of  requesting  the  extension of these  license
lives for several nuclear generating stations.  The decommissioning of a nuclear
generating  station involves the  decontamination  of structures and components,
the removal of high-level and low-level  radioactive materials from the site for
disposal at a licensed facility and for certain stations, the restoration of the
station   sites  to  a  natural   state.   We  estimate   that,   once  started,
decommissioning  of a site can generally be completed in 10 years.  Based on the
projected   extended  license  lives  of  our  nuclear  plants,  we  will  begin
decommissioning  our plants from 2014 through 2056, with expenditures  primarily
occurring when our operating plants are  decommissioned,  during the period from
2029 through 2056.

     We currently recover certain  decommissioning costs in regulated rates. The
amounts  recovered are  deposited in trust  accounts and invested for funding of
future  decommissioning  costs for active and inactive generating units. As part
of our 2001  restructuring,  the  generation-related  assets and  liabilities of
ComEd and PECO were transferred to Generation. The accounting for our receipt of
decommissioning  collections  and  recognition  of  decommissioning  liabilities
varies between the plants that were  previously  owned by ComEd or by PECO prior
to restructuring.

     We account  for the current  period's  cost of  decommissioning  related to
generating  plants previously owned by PECO by following  regulatory  accounting
principles and recording a charge to  depreciation  expense and a  corresponding
liability  in   accumulated   depreciation   concurrent   with   decommissioning
collections  from rate payers.  Our  regulatory  accounting  principles  for the
generating

                                       54


stations  previously owned by ComEd were  discontinued  when those stations were
transferred  to Generation.  Those stations  included both operating and retired
units.   For  operating   units,   the  difference   between  the  current  cost
decommissioning   estimate  and  the   decommissioning   liability  recorded  in
accumulated depreciation is amortized to depreciation expense on a straight-line
basis  over  the  remaining   lives.   For  retired  units,   the  current  cost
decommissioning  estimate is recorded in deferred credits and other  liabilities
and accreted to depreciation expense.

     Under  regulatory  accounting  principles,  gains and losses on  marketable
securities  held in the  nuclear  decommissioning  trust  funds are  reported in
accumulated   depreciation.   After   regulatory   accounting   principles   are
discontinued,  unrealized gains and losses on marketable  securities held in the
nuclear   decommissioning   trust  funds  are  reported  in  accumulated   other
comprehensive  income.  Realized gains and losses on decommissioning trust funds
are reflected in other income and deductions in our  Consolidated  Statements of
Income.  Due to the sharp  declines in the equity market since the third quarter
of  2000,  the  value  of our  nuclear  decommissioning  trust  funds  has  also
decreased.  In 2002,  contributions  to these trust funds of $112  million  were
offset by net realized and unrealized losses of $224 million,  resulting in a 4%
decrease in the trust funds'  balance at December 31, 2002  compared to December
31, 2001.  We believe that the amounts that ComEd and PECO are  recovering  from
customers  through  electric rates,  along with the earnings on the trust funds,
will be sufficient to fund our decommissioning obligations.

     Cost  estimates  for  decommissioning  our  nuclear  facilities  have  been
prepared  by an  independent  engineering  firm and reflect  currently  existing
regulatory  requirements and available  technology.  Our current estimate of our
nuclear facilities'  decommissioning cost is $7.4 billion in current year (2003)
dollars.  Calculating this estimate involves  significant  assumptions about the
expected increases in decommissioning costs relative to general inflation rates,
changes in the regulatory environment or regulatory requirements, and the timing
of  decommissioning.  Significant  changes in these assumptions could materially
affect the liabilities and future costs related to  decommissioning  recorded in
our Consolidated Financial Statements.

     The  estimated  service life of the nuclear  station is also a  significant
assumption  because   decommissioning   and  depreciation  costs  are  generally
recognized over the life of the generating station. In 2001, we extended nuclear
station service lives, over which the decommissioning  costs are recognized,  by
20 years. Effective April 1, 2001, we extended the estimated service lives by 20
years for three  nuclear  stations.  Effective  July 1, 2001,  we  extended  the
estimated  service  lives by 20 years for the  remainder  of Exelon's  operating
nuclear  stations.   These  changes  were  based  on  engineering  and  economic
feasibility studies we performed considering, among other things, future capital
and  maintenance  expenditures  at these plants.  The service life  extension is
subject to NRC approval of an extension of existing NRC operating licenses. As a
result of the change, net income for 2002 and 2001 increased  approximately $132
million ($79 million,  net of income taxes) and  approximately  $90 million ($54
million, net income taxes), respectively.  Although we consider the service life
extension  authorization  to be probable,  if the  extensions  were denied,  our
results of  operations  would be adversely  impacted by  increased  depreciation
rates and accelerated future decommissioning payments.

     SFAS No. 143. The  accounting  for our nuclear  decommissioning  obligation
will be affected by the adoption of SFAS No. 143, "Asset Retirement Obligations"
(SFAS No.  143)  effective  January 1, 2003.  SFAS No. 143  provides  accounting
requirements  for retirement  obligations  associated  with tangible  long-lived
assets. Retirement obligations associated with long-lived assets included within
the scope of SFAS No. 143 are those for which there is a legal  obligation under
existing  or  enacted  law,  statute,  written  or  oral  contract  or by  legal
construction under the doctrine of promissory estoppel.

     The effect of this cumulative adjustment on nuclear decommissioning will be
to  change  the

                                       55


decommissioning  liability  to  reflect  the fair  value of the  decommissioning
obligation  at the balance sheet date.  Additionally,  SFAS No. 143 will require
the recording of an asset related to the decommissioning obligation,  which will
be amortized over the remaining lives of the plants. The net difference, between
the  asset  recognized  and  the  adjustment  to the  decommissioning  liability
recorded  upon  adoption  of SFAS No.  143,  will be  charged  to  earnings  and
recognized as a cumulative  effect of a change in accounting  principle,  net of
expected  regulatory  recovery and net of taxes. The  decommissioning  liability
will  then   represent  the  fair  value  of  the   obligation  for  the  future
decommissioning  of the  plants  and,  as a result,  accretion  expense  will be
accrued on this liability until the obligation is satisfied.

     As noted above,  we currently  record the  obligation  for  decommissioning
ratably  over the  lives of the  plants.  We are  currently  in the  process  of
evaluating the impact of adopting SFAS No. 143 on our financial condition. Based
on the current information and the  credit-adjusted  risk-free rate, we estimate
the increase in 2003 non-cash  expense to impact  earnings before the cumulative
effect of a change in  accounting  principle for the adoption of SFAS No. 143 by
approximately  $24 million,  after income taxes.  Additionally,  the adoption of
SFAS No. 143 is expected  to result in a large,  non-cash,  one-time  cumulative
effect of a change in accounting principle gain of at least $1.5 billion,  after
income  taxes.  The $1.5  billion gain and the $24 million  charge  includes our
share of the impact of the SFAS No. 143 adoption  related to  AmerGen's  nuclear
plants.  These impacts are based on our current  interpretation  of SFAS No. 143
and are subject to continued refinement based on the finalization of assumptions
and  interpretation  at  the  time  of  adopting  the  standard,  including  the
determination  of the  credit-adjusted  risk-free rate.  Under SFAS No. 143, the
fair  value  of the  nuclear  decommissioning  obligation  will  continue  to be
adjusted on an ongoing basis as these model input factors change.

     In accordance  with SFAS No. 143, we used a  probabilistic  cash flow model
with   multiple   scenarios  in  order  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.  Key assumptions used in our  determination of fair value as defined
in SFAS No. 143 include:

     o    decommissioning cost studies prepared by a third party

          -    these decommissioning  studies represent a marketplace assessment
               of costs and the timing of  retirement  activities  validated  by
               comparison  to current  decommissioning  projects and other third
               party estimates

     o    annual cost escalation  studies to determine  escalation factors based
          on  inflation  indices  used in  decommissioning  cost studies for the
          following major categories:

          -    labor,

          -    equipment and materials,

          -    energy,

          -    other (taxes, insurance, fees, etc.), and

          -    low-level radioactive waste disposal costs.

     o    use of  probabilistic  cash flow  models  to  measure  the fair  value
          including:

          -    the probability of various cost levels, and

          -    the  probability of various timing  scenarios  incorporating  the
               factors  of  current  license  lives and life  extension  and the
               timing of DOE acceptance for disposal of our spent nuclear fuel.

     Under the Nuclear Waste Policy Act of 1982 (NWPA),  the U.S.  Department of
Energy (DOE) is responsible  for the selection and  development of  repositories
for, and the disposal of, spent nuclear fuel and  high-level  radioactive  waste
(SNF). As required by the NWPA,  ComEd and PECO, each signed a contract with the
DOE  (Standard  Contract) to provide for  disposal of SNF from their  respective
nuclear generating stations. The NWPA and the Standard Contract required the DOE
to begin taking  possession of SNF generated by nuclear  generating  units by no
later than January 31, 1998. The DOE, however,

                                       56


failed to meet that deadline and its performance will be significantly  delayed.
The DOE currently  estimates it will open a SNF facility in 2010.  This extended
delay   requires  us  to  retain   possession  of  the  SNF,   thus   increasing
decommissioning  costs  including the operation and maintenance of facilities to
store SNF until the DOE removes it from our sites.

     The NRC regulatory guidance suggests that  decommissioning  cost studies be
updated every five years. Most of our studies were prepared in 1995 and 1996 and
are in the  process  of  being  updated.  Although  no  significant  changes  in
decommissioning technologies have occurred since the studies were performed, and
annual cost escalation  studies are performed to determine the escalation factor
applied to the base year cost study,  changes in these cost studies could have a
material impact on the fair value of the nuclear decommissioning obligation. The
final determination of the cumulative effect of a change in accounting principle
is also in part a function of the credit-adjusted  risk-free rate at the time of
the adoption of the standard. Additionally, although over the life of the plant,
the charges to earnings  for the  depreciation  of the asset and the interest on
the  liability  will be equal to the amounts that would have been  recognized as
decommissioning  expense  under  the  current  accounting,  the  timing of those
charges will change and in the  near-term  period  subsequent  to adoption,  the
depreciation  of the asset and the  interest on the  liability  are  expected to
result in an increase in expense.

Asset Impairments

     Long-Lived  Assets  and  Investments.  SFAS No.  144,  "Accounting  for the
Impairment  or  Disposal  of  Long-Lived  Assets"  (SFAS No.  144),  establishes
accounting  and  reporting  standards  for both the  impairment  and disposal of
long-lived assets. SFAS No. 144 continues the FASB requirements that:

     o    an impairment loss be recognized if the carrying amount of an asset is
          not recoverable from its undiscounted cash flows, and

     o    the impairment loss be measured as the difference between the carrying
          amount and the fair value of the asset.

Accounting Principles Board Opinion No. 18, "The Equity Method of Accounting for
Investment in Common Stock,"  requires that an impairment loss be recognized for
an investment if the investment  declines in fair value below its amortized cost
basis, and this decline is judged to be other-than-temporary.

     We continually  monitor our  investments  and businesses and the markets in
which these businesses  operate in order to determine events that may trigger an
impairment.  We have tested our businesses and  investments  for  recoverability
whenever events or changes in circumstances indicate that their carrying amounts
may not be recoverable. Such triggering events may include a current expectation
that there is a likelihood  of 50% or greater  that a  long-lived  asset will be
sold,  competitors'  technological  advancement,  accelerated  distributions  of
public holdings at a loss,  lack of  achievability  of financial  results versus
plan, limited access to capital, or the loss of a major customer,  among others.
The analysis of impairment for long-lived and intangible assets is subject to an
undiscounted cash flow analysis that requires significant assumptions.

     In 2002,  we did not  identify  factors  through  our review  process  that
indicated  potential  impairment  of  property,  plant  and  equipment  or other
long-lived assets with the exception of investments at our Enterprises  business
unit.  Enterprises  wrote  down  $41  million  of  investments  in 2002  when we
discovered certain triggering events, such as those described above.

     Goodwill. Under SFAS No. 142, goodwill is also subject to an assessment for
impairment  using a two-step fair value based test, the first step of which must
be performed at least annually,  or more  frequently if events or  circumstances
indicate that  goodwill  might be impaired.  The reporting  units of Exelon that
were  determined  to have had goodwill  allocated to them were Energy  Delivery,
Exelon's

                                       57


infrastructure  services  business  (InfraSource),  the energy services business
(Exelon  Services)  and the  competitive  retail energy sales  business  (Exelon
Energy).  All of Energy  Delivery's  goodwill is at ComEd.  If an  impairment is
determined at ComEd, the amount of the impaired goodwill will be written-off and
expensed  at ComEd.  However,  under  current  accounting  guidance,  a goodwill
impairment  charge at ComEd  may not  affect  Exelon's  results  of  operations.
Exelon's goodwill  impairment test would include assessing the cash flows of the
entire Energy Delivery business segment (a single Reporting Unit, which includes
PECO,  as defined  under  current  accounting  guidance),  not just ComEd's cash
flows.

     We  performed  the  first  step of the SFAS No.  142  impairment  analysis,
comparing the fair value of a reporting unit to its carrying  amount,  including
goodwill,  as of January 1, 2002, upon adoption of SFAS No. 142. That first step
indicated no  impairment  of ComEd's  goodwill but showed an  impairment  of the
goodwill  recorded in  Enterprises'  reporting  units.  In performing the Step I
tests as  prescribed  in SFAS No. 142,  ComEd and  Enterprises  determined  that
discounted  cash flow  models  would  provide  the most  appropriate  measure to
determine Step I fair value. Consistent with the guidance in SFAS No. 142, ComEd
and Enterprises  prepared multiple scenario discounted cash flow models in order
to  determine  the value for Step I of SFAS No. 142.  These  models use multiple
assumptions  including revenue growth rates,  general expense  escalation rates,
allowed return on equity, a risk-adjusted  discount rate and long-term  earnings
multiples of comparable companies.  In addition to the above-noted  assumptions,
ComEd's model included varying assumptions regarding:

     o    The  timing of future  rate case  filings to  establish  new rates for
          bundled  service after the then scheduled 2004  expiration of the rate
          freeze  period,  which  has  subsequently  been  extended  to  2006 by
          Illinois law. Rate changes were assumed to occur at various  points in
          2005 through 2007 in the different scenarios.

     o    The cash flow  impact of the  expiration  of the rate  freeze  and the
          resolution of  uncertainties  regarding  future  commodity risk at the
          expiration of the current purchase power agreements, the resolution of
          ComEd's POLR obligation and various other risks and uncertainties.

     The  results of the Step I  analysis  for ComEd  showed a weighted  average
probabilistic valuation of the multiple scenario discounted cash flows in excess
of ComEd's book carrying amount, including goodwill, at December 31, 2001. Since
the Step I calculated  fair value was in excess of book value, we could conclude
that ComEd's goodwill of $4.9 billion was not impaired.  The results of the Step
I analysis for Enterprises,  however,  calculated weighted average probabilistic
valuations of the multiple scenario  discounted cash flows of less than the book
carrying value,  including goodwill, of InfraSource,  Exelon Services and Exelon
Energy.  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. Enterprises' goodwill balance was $76 million at December 31, 2002.

     As required by SFAS No. 142, Exelon  performed the annual update of ComEd's
and  Enterprises'   goodwill  impairment  analyses  using  a  November  1,  2002
measurement  date. These valuations  determined the Step I calculated fair value
of both  ComEd and the  Enterprises'  units to be in excess of their  respective
book values at November 1, 2002.  Since the Step I calculated  fair value was in
excess of book value,  we concluded that goodwill was not impaired.  Again,  the
probabilistic  discounted  cash flows model used in these analyses  included the
significant  assumptions  noted  above.  Rate  changes  were assumed to occur at
various  points in 2007 through 2009 in the different  scenarios for ComEd based
on the June 2002 extension of the rate freeze.

     Modifications  to any  of the  assumptions  discussed  above,  particularly
changes in discount rates,  long-term earnings multiples of comparable companies
used to determine terminal values, and the

                                       58


expected  results of rate  proceedings,  could result in a future  impairment of
goodwill.  Actual results as well as market  conditions in upcoming periods will
impact the  probabilities  of scenarios used in the models.  If the estimates of
future cash flows in both the ComEd and  Enterprises  models had been 10% lower,
respectively, those discounted cash flows would still have been greater than the
carrying values of ComEd and Enterprises,  respectively. As we were not required
to perform a Step II  analysis  at the  November  1, 2002  measurement  date for
either ComEd or  Enterprises,  a dollar amount for any potential  impairment has
not been determined.  Because goodwill  represents  approximately 85% of ComEd's
common equity,  a potential  future  impairment of goodwill could  significantly
impact  ComEd's  ability to pay  dividends to Exelon  under PUHCA.  The Illinois
legislation  provides that  reductions to ComEd's  common equity  resulting from
goodwill  impairments will not impact ComEd's  earnings cap calculation  through
2006.

Defined Benefit Pension and Other Postretirement Welfare Benefits
     We sponsor defined benefit pension plans and postretirement welfare benefit
plans  applicable to essentially all ComEd,  PECO,  Generation and BSC employees
and certain Enterprises  employees.  The costs of providing benefits under these
plans are dependent on historical  information  such as employee age,  length of
service and level of compensation, and the actual rate of return on plan assets.
Also, we utilize  assumptions  about the future,  including the expected rate of
return on plan assets, the discount rate applied to benefit obligations, rate of
compensation increase and the anticipated rate of increase in health care costs.
In accordance with SFAS No. 87,  "Employers'  Accounting for Pensions" (SFAS No.
87) and SFAS No. 106, "Employers'  Accounting for Postretirement  Benefits Other
than Pensions"  (SFAS No. 106) the impact of changes in these factors on pension
and other  postretirement  welfare benefit  obligations is generally  recognized
over  the  expected   remaining  service  life  of  the  employees  rather  than
immediately recognized in the income statement.

     In selecting  the expected  rate of return on plan  assets,  we  considered
historical and expected returns for the types of investments the plans hold. Our
pension trust assets have lost $581 million,  and $265 million,  and gained $173
million in 2002,  2001 and 2000,  respectively.  The long-term  expected rate of
return on plan assets (EROA)  assumption  used in  calculating  pension cost was
9.5% at January 1, 2002,  2001 and 2000.  We generally  maintain 60% of our plan
assets  in  equity  securities  and  40%  of our  plan  assets  in  fixed-income
securities.  Each  quarter we review the actual asset  allocations  and follow a
rebalancing  procedure  in order to remain  within an  allowable  range of these
targeted  percentages.  Based on our asset  allocation and long-term  historical
returns for both equity and fixed-income securities,  we set our EROA at 9.0% as
of  January  1,  2003 in  order  to  calculate  2003  pension  cost.  Our  other
postretirement benefit assets have lost $125 million, $14 million and $7 million
in 2002,  2001 and 2000,  respectively.  The EROA assumption used in calculating
the other  postretirement  benefit  obligation was 8.8% at January 1, 2002, 2001
and 2000, respectively.  We will use an EROA assumption of 8.4% as of January 1,
2003 in order to calculate the 2003 other postretirement  benefit costs. A lower
EROA is used in the  calculation  of other  postretirement  benefit costs as the
other  postretirement  benefit  trust  activity is partially  taxable  while the
pension trust activity is non-taxable.

     We use the  Moody's Aa  Corporate  Bond Index as a basis in  selecting  the
discount  rate. As described in Note 15 of the Notes to  Consolidated  Financial
Statements,  we set the assumed discount rate at 7.35% and 6.75% at December 31,
2001 and 2002,  respectively,  in our  estimate  of  pension  expense  and other
postretirement benefit costs.

         The  following  table  illustrates  the  effect of  changing  the major
actuarial assumptions discussed above:

     The  assumptions  are  reviewed  at the  beginning  of each year during our
annual review  process.  The impact of  assumption  changes are reflected in the
recorded  pension amounts  consistent with assumption  changes as they occur. As
these  assumptions  change from period to period,  recorded  pension amounts and
funding requirements could also change.

     Our pension and other postretirement benefit plans have unrecognized losses
of $2.1 billion and $0.8  billion,  respectively,  at December  31,  2002.  This
unrecognized  loss  primarily  represents  the  difference  between the expected
return on plan assets and the actual return on plan assets that has not yet been
recognized  in pension or other  postretirement  benefit  expense.  We generally
amortize these unrecognized  (gains)/losses over five years; however, the annual
amortization amounts vary based on actuarial  determinations.  Recognition of an
unrecognized  loss will result in  increased  net  periodic  pension  cost going
forward.

     Primarily  as a result of sharp  declines in the equity  markets  since the
third quarter of 2000, we  recognized  an additional  minimum  liability of $1.0
billion,  net of  income  taxes,  and an  intangible  asset of $211  million  as
prescribed  by SFAS No. 87 in the fourth  quarter  of 2002.  The  liability  was
recorded as a reduction to shareholders' equity, and the equity will be restored
to the  balance  sheet in  future  periods  when the fair  value of plan  assets
exceeds the  accumulated  benefit  obligation.  The recording of this additional
minimum  liability  did not affect net income or cash flow in 2002 or compliance
with debt covenants;  however,  pension cost and cash funding requirements could
increase in future years without a substantial recovery in the equity markets.

     Our defined  benefit  pension  plans  currently  meet the  minimum  funding
requirements  of the Employment  Retirement  Income Security Act of 1974 without
any additional  funding;  however,  we made a discretionary  tax-deductible plan
contribution  of $150  million  in the fourth  quarter of 2002  funded by ComEd,
Generation and BSC. We also expect to make a discretionary  tax-deductible  plan
contribution in 2003 of $300 million to $350 million.

     Approximately $93 million was included in operating and maintenance expense
in 2002 for the cost of our pension and postretirement  benefit plans, exclusive
of the 2002 charges for employee severance programs.  Although the 2003 increase
in pension and postretirement benefit cost will depend on market conditions, our
estimate is that expense  will  increase by  approximately  $125 million in 2003
from 2002  expense  levels as the result of the effects of the decline in market
value of plan  assets in 2002,  the decline in discount  rate and  increases  in
health care costs.


                                       60


     In 2001,  we  adopted a cash  balance  pension  plan.  All  management  and
electing union employees who were hired by us after 2001 became  participants in
the plan.  Approximately 4,700 management employees who were active participants
in our  previous  qualified  defined  benefit  plans at  December  31,  2000 and
remained  employed  by us on January 1, 2002  elected  to  transfer  to the cash
balance plan.  Participants in the cash balance plan, unlike participants in the
other defined  benefit plans,  may request a lump-sum cash payment upon employee
termination.  This may result in increased cash  requirements  from pension plan
assets, which may increase future funding to the pension plan.


Stock-Based Compensation Plans
     We  maintain  a  Long-Term  Incentive  Plan  (LTIP) for  certain  full-time
salaried employees and previously maintained a broad-based incentive program for
certain other employees.  The types of long-term incentive awards that have been
granted  under the LTIP are  non-qualified  options  to  purchase  shares of our
common stock and common stock awards. The exercise price of the stock options is
equal to the fair  market  value of the  underlying  stock on the date of option
grant.  Options  granted under the LTIP and the  broad-based  incentive  program
become  exercisable  upon  attainment  of a target share value and/or time.  All
options expire 10 years from the date of grant.

     At December 31, 2002, there were 13,000,000 options authorized for issuance
under the LTIP and 2,000,000 options authorized under the broad-based  incentive
program.  We currently  follow the  disclosure-only  provisions of SFAS No. 123,
"Accounting  for  Stock-Based  Compensation"  (SFAS No.  123).  If we elected to
account for our stock-based  compensation  plans based on SFAS No. 123, we would
have  recognized  compensation  expense  of $33  million,  $26  million  and $25
million, for 2002, 2001 and 2000, respectively.

     We use an  independent  actuarial  firm to calculate  the fair value of the
options and to assist in the  development  of amounts  required to be  disclosed
under SFAS No. 123. The key assumptions used in this determination of fair value
are the expected volatility of the stock price, based on historical information;
the expected  life of the options,  based on the vesting  period and  expiration
date  of  the  options;  the  estimated  dividend  yield,  based  on  historical
information  adjusted  for  material  known future  changes;  and the  risk-free
interest rate, based on the yield of a United States Treasury Strip available on
the date of the grant and expiring at the  approximate end of the option's term.
Changes in these  assumptions  could have  resulted in  material  changes in the
amounts  disclosed  under  SFAS  No.  123 in  Notes  1 and 17 of  the  Notes  to
Consolidated Financial Statements.


                                       61


Business Combinations
     In the three year period ended December 31, 2002, we have completed several
business  combinations  and asset  acquisitions.  We adopted  SFAS No. 141 as of
January 1, 2002. SFAS No. 141 is effective for business  combinations  initiated
after June 30, 2001.  SFAS No. 141 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.  Under the purchase  method of  accounting,  purchased  assets and
liabilities  must be recorded at their fair value. If a quoted fair value is not
readily  available  for the majority of assets and  liabilities  exchanged,  the
determination of this fair value requires the use of significant judgment,  both
by  management  and  outside  experts  engaged  to assist in this  determination
process.  Changes in the  assumptions  made in determining the fair values could
have  resulted in material  changes in the  amounts  disclosed  in Note 3 of the
Notes to Consolidated Financial Statements. There would also be an impact on our
financial results.  If the fair value of property,  plant and equipment acquired
in a business  combination  would have been higher,  and an amount  allocated to
goodwill in the business combination lower, depreciation expense would have been
higher.  Conversely, if the fair value of property, plant and equipment acquired
in a business  combination  would have been lower,  and an amount  allocated  to
goodwill in the business  combination  higher,  depreciation  expense would have
been lower. For example,  if the $2 billion fair value of the generating  plants
acquired in the Merger was estimated to be 1% higher,  then annual  depreciation
expense would be less than $1 million  higher and goodwill  amortization,  which
ceased in 2002, would have been less than $1 million lower annually.

Unbilled Energy Revenues
     Revenues related to the sale of energy are generally  recorded when service
is rendered or energy is delivered to customers. The determination of the energy
sales to  individual  customers,  however,  is based on  systematic  readings of
customer meters generally on a monthly basis. At the end of each month,  amounts
of energy  delivered  to  customers  during the month since the date of the last
meter reading are estimated and corresponding unbilled revenue is recorded. This
unbilled revenue is estimated each month based on daily customer demand measured
by generation  volume,  estimated  customer usage by class,  estimated losses of
energy during delivery to customers  (line loss) and applicable  customer rates.
Customer  accounts  receivable as of December 31, 2002 include  unbilled  energy
revenues of $442  million.  Increases  in volumes  delivered  to the  utilities'
customers in the period would increase unbilled  revenue.  Changes in the timing
of meter reading  schedules  and the number and type of customers  scheduled for
each meter  reading  date would  also have an effect on the  estimated  unbilled
revenue.

Long-Term Contract Accounting
     Enterprises  recognizes  contract revenue and profits on certain  long-term
fixed-price contracts by the  percentage-of-completion  method of accounting. As
contract  work is completed,  the  corresponding  percentage of total  estimated
profit on the contract is recognized in the  Consolidated  Statements of Income.
In determining the amount of revenue to recognize,  we are required to estimate,
at the  beginning of the  contract,  the total costs and profits  expected to be
recorded under the contract over its contract term,  and, on an on-going  basis,
the recoverability of costs related to change orders. Changes in these estimates
could result in the  recognition  of  differences  in earnings.  At December 31,
2002,  Current  Assets  included  $70 million of costs and earnings in excess of
billings on uncompleted  contracts and Current Liabilities  included $44 million
of billings and earnings in excess of costs on uncompleted contracts.

Environmental Costs
     As of December 31,  2002,  we had accrued  liabilities  of $156 million for
environmental  investigation and remediation  costs. These liabilities are based
upon  estimates  with  respect  to the  number  of  sites  for  which we will be
responsible,  the  scope  and cost of work to be  performed  at each  site,  the
portion of costs that will be shared  with other  parties  and the timing of the
remediation  work.  Where


                                       62


timing  and  costs  of  expenditures  can be  reliably  estimated,  amounts  are
discounted. These amounts represent $97 million of the accrued liabilities total
above.  Where  timing and  amounts  cannot be  reliably  estimated,  amounts are
recognized on an undiscounted  basis.  Such amounts represent $59 million of the
accrued liabilities total above.  Estimates can be affected by the factors noted
above as well as by changes in  technology  and  changes in  regulations  or the
requirements of local governmental authorities.


Quantitative and Qualitative Disclosures About Market Risk

     We are exposed to market risks  associated with commodity  prices,  credit,
interest  rates  and  equity  prices.  The  inherent  risk in  market  sensitive
instruments  and positions is the potential loss arising from adverse changes in
commodity  prices,  counterparty  credit,  interest  rates and  equity  security
prices.  Our RMC sets  forth  risk  management  philosophy  and  objectives  and
establishes procedures for risk assessment, control and valuation,  counterparty
credit  approval,  and the monitoring  and reporting of derivative  activity and
risk  exposures.  The RMC is chaired by the chief risk  officer and includes the
chief financial officer, general counsel, treasurer, vice president of corporate
planning and officers  from each of the business  units.  The RMC reports to the
board of directors on the scope of our derivative activities.

Commodity Price Risk

     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.

     Normal Operations and Hedging  Activities.  Electricity  available from our
owned or contracted generation supply in excess of our obligations to customers,
including Energy Delivery's retail load, is sold into the wholesale markets.  To
reduce  price  risk  caused  by  market  fluctuations,  we enter  into  physical
contracts as well as derivative contracts,  including forwards,  futures, swaps,
and options,  with approved  counterparties to hedge our anticipated  exposures.
The maximum  length of time over which cash flows related to energy  commodities
are currently  being hedged is 4 years.  We have an estimated 90% hedge ratio in
2003 for our  energy  marketing  portfolio.  This  hedge  ratio  represents  the
percentage  of  our  forecasted  aggregate  annual  generation  supply  that  is
committed to firm sales,  including sales to Energy  Delivery's retail load. The
hedge ratio is not fixed and will vary from time to time  depending  upon market
conditions,  demand and  volatility  and during peak  periods our amount  hedged
declines to meet our commitment to Energy  Delivery.  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 our  non-trading  portfolio  associated  with a ten percent
reduction in the annual average  around-the-clock market price of electricity is
an approximately $37 million decrease in net income, or approximately  $0.11 per
share.  This sensitivity  assumes a 90% hedge ratio and that price changes occur
evenly throughout the year and across all markets.  The sensitivity also assumes
a static  portfolio.  We expect to  actively  manage our  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
our portfolio.


                                       63


     Proprietary  Trading  Activities.  We began to use financial  contracts for
proprietary trading purposes in the second quarter of 2001.  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 our
energy  marketing  portfolio  and  represent a very small portion of our overall
energy  marketing  activities.  For  example,  the  limit on open  positions  in
electricity  for any  forward  month  represents  less  than 1% of our 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.

     Our energy contracts are accounted for under SFAS No. 133. Most non-trading
contracts  qualify for the normal  purchases and normal sales  exemption to SFAS
No.  133  discussed  in  Critical  Accounting  Estimates.  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 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  our  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. We do not
consider our proprietary  trading to be a significant  activity in our business;
however,   we  believe  it  is  important  to  include  these  risk   management
disclosures.

     The  following  table  describes  the  drivers  of our energy  trading  and
marketing  business and gross margin  included in the income  statement  for the
year ended December 31, 2002. Normal operations and hedging activities represent
the marketing of  electricity  available from  Generation's  owned or contracted
generation,  including  Energy  Delivery'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 our  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 we believe
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
December  31,  2002 and may  change as a result  of  changes  in these  factors.
Management  uses its best estimates to determine the fair


                                       65


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 and trading  activities and such
variations could be material.

     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  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.  We  measure  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,  we 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 December 31, 2002.  The data in the
table gives an  indication  of the  magnitude  of SFAS No. 133 hedges we have 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 our hedges. The
table also includes a roll-forward  of Accumulated  Other  Comprehensive  Income
related to cash flow  hedges for the year ended  December  31,  2002,  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.

     We use 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 our 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.

     We  estimate  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  backtested  daily
against daily changes in mark-to-market  value for proprietary trading activity.
Value-at-Risk  assumes that normal market conditions  prevail and that there are
no changes in  positions.  We use a 95%  confidence  interval,  one-day  holding
period,  one-tailed  statistical measure in calculating our VaR. This means that
we may state that there is a one in 20 chance  that if prices  move  against our
portfolio positions,  our pre-tax loss in liquidating our portfolio in a one-day
holding  period would exceed the  calculated  VaR. To account for unusual events
and loss of liquidity, we use stress tests and scenario analysis.

     For  financial  reporting  purposes  only,  we calculate  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
December 31, 2002.

Credit Risk

     Credit  risk for Energy  Delivery  is managed by each of ComEd's and PECO's
credit and  collection  policies,  which are  consistent  with state  regulatory
requirements.  ComEd and PECO are each currently obligated to provide service to
all electric customers within their respective franchised  territories.  For the
year  ended  December  31,  2002,  ComEd's  ten  largest  customers  represented
approximately  3% of  its  retail  electric  revenues  and  PECO's  ten  largest
customers  represented  approximately  8% of its retail  electric  revenues.  We
record a provision for uncollectible accounts,  based upon historical experience
and  third-party  studies,  to provide for the potential loss from nonpayment by
these customers.

     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 December 31, 2002. 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 figures in the table below do not include sales to  Generation's  affiliates
or exposure  through  Independent  System  Operators  (ISOs) which are discussed
below.

     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  December  31,  2002,
Generation had a net  receivable  from Dynegy of  approximately  $3 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 December 31, 2002,
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.  We
estimate,  as a 49.9% owner of Sithe,  that the  impairment  would  result in an
after-tax reduction of our equity earnings of approximately $10 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,  we would likely incur a further  impairment  associated with
the Independence plant. Depending upon the timing of Dynegy's failure to fulfill
its  obligations  and the  outcome of any  restructuring  initiatives,  we could
realize an after-tax  charge of between $0 and $130  million.  In the event of a
sale of our  investment in Sithe to a third party,  proceeds from the sale could
be negatively  impacted by  approximately  $100 million,  or  approximately  $65
million net of income taxes.

     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.

     Generation  participates  in the following  established,  real-time  energy
markets,  which are  administered  by ISOs:  PJM, New England ISO, New York ISO,
California ISO, Midwest ISO, Inc.,  Southwest Power Pool, Inc. and Texas,  which
is  administered by the Electric  Reliability  Council of

                                       69


Texas.  In these areas,  power is traded through  bilateral  agreements  between
buyers and sellers and on the spot  markets  that are  operated by the ISOs.  In
areas where there is no spot market,  electricity  is purchased  and sold solely
through bilateral  agreements.  For sales into the spot markets  administered by
the ISOs, the ISO maintains  financial  assurance  policies that are established
and enforced by those administrators.  The credit policies of the ISOs may under
certain circumstances require that losses arising from the default of one member
on  spot  market   transactions   be  shared  by  the  remaining   participants.
Non-performance  or  non-payment  by a  major  counterparty  could  result  in a
material adverse impact on our financial condition, results of operations or net
cash flows.

     Our consolidated  balance sheet includes a $445 million net investment in a
direct  financing  lease as of  December  31,  2002.  The  investment  in direct
financing leases  represents future minimum lease payments due at the end of the
thirty-year life of the lease of $1,492 million,  less unearned income of $1,047
million.  The future  minimum lease  payments are  supported by  collateral  and
credit enhancement measures including letters of credit, surety bonds and credit
swaps issued by high credit quality financial institutions. Management regularly
evaluates the credit  worthiness of our  counterparties to this direct financing
lease.

Interest Rate Risk

     We use a  combination  of  fixed  rate and  variable  rate  debt to  reduce
interest rate exposure.  We also use interest rate swaps when deemed appropriate
to  adjust  exposure  based  upon  market  conditions.   Additionally,   we  use
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 achieve a lower cost of capital.  As of December 31, 2002, a hypothetical 10%
increase in the interest rates  associated  with variable rate debt would result
in a $5 million decrease in pre-tax earnings for 2003.

     We have  entered  into fixed to  floating  interest  rate swaps in order to
maintain our targeted percentage of variable rate debt,  associated with ComEd's
debt  issuances in the aggregate  amount of $485 million.  At December 31, 2002,
these  interest rate swaps,  designated as fair value hedges,  had a fair market
value of $41 million based on the present value difference  between the contract
and market rates at December  31, 2002.  If we had not had the fair value hedges
in place at ComEd,  we would  have  recognized  an  additional  $14  million  in
interest expense in 2002.

     During 2002 and 2001,  ComEd  entered into  forward-starting  interest rate
swaps,  with an  aggregate  notional  amount of $830  million and $250  million,
respectively,  in  anticipation of the issuance of debt. In connection with bond
issuances in 2002,  ComEd  settled  forward-starting  interest rate swaps in the
aggregate  notional  amount of $450 million,  resulting in a $10 million pre-tax
loss recorded as a regulatory  asset,  which is being amortized over the life of
the related  debt in interest  expense.  At December  31,  2002,  ComEd had $630
million of forward-starting interest rate swaps outstanding. These interest rate
swaps,  designated as cash flow hedges,  had a fair market value exposure of $52
million at December 31, 2002. As it remained  probable that the debt  issuances,
the  forecasted  future  transactions  these swaps were  hedging,  would  occur,
although  the  issuances  had been  delayed,  we  continued to account for these
interest rate swap  transactions  as hedges.  In connection with ComEd's January
22, 2003 issuance of $700 million in First Mortgage  Bonds, we settled swaps, in
the aggregate  notional  amount of $550  million,  for a payment of $43 million,
which will be recorded as a regulatory  asset and amortized over the life of the
debt issuance.

     During 2002, PECO entered into  forward-starting  interest rate swaps, with
an aggregate notional amount of $200 million, in anticipation of the issuance of
debt at PECO. These interest rate swaps were designated as cash flow hedges.  In
connection  with bond issuances in 2002,  PECO settled these  forward-

                                       70


starting  interest rate swaps resulting in a $5 million pre-tax loss recorded in
OCI, which is being amortized over the life of the related debt.

     PECO also had 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 December 31, 2002, these interest
rate swaps had an aggregate fair market value exposure of $22 million.

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

     Under the terms of the Sithe  Boston  Generation,  LLC (SBG)  project  debt
facility,  SBG is  required  to  effectively  fix  the  interest  rate on 50% of
borrowings  under the facility  through its maturity in 2007. As of December 31,
2002, we have entered into interest rate swap agreements  which have effectively
fixed  the  interest  rate on $861  million  of  notional  principal,  or 83% of
borrowings  outstanding  at December 31, 2002. The fair market value exposure of
these swaps, designated as cash flow hedges, is $92 million.

     The  aggregate  fair value of our interest  rate swaps  designated  as fair
value  hedges  that would  have  resulted  from a  hypothetical  50 basis  point
decrease in the spot yield at December  31, 2002 is estimated to be $49 million.
If the derivative  instruments  had been  terminated at December 31, 2002,  this
estimated fair value represents the amount the counterparties would pay us.

     The  aggregate  fair value of our interest  rate swaps  designated  as fair
value  hedges  that would  have  resulted  from a  hypothetical  50 basis  point
increase in the spot yield at December  31, 2002 is estimated to be $33 million.
If the derivative  instruments  had been  terminated at December 31, 2002,  this
estimated fair value represents the amount the counterparties would pay us.

     The aggregate fair value exposure of our interest rate swaps  designated as
cash flow hedges that would have  resulted  from a  hypothetical  50 basis point

If the derivative  instruments  had been  terminated at December 31, 2002,  this
estimated fair value represents the amount we would pay to the counterparties.

     The aggregate fair value exposure of our interest rate swaps  designated as
cash flow hedges that would have  resulted  from a  hypothetical  50 basis point
increase in the spot yield at December 31, 2002 is estimated to be $132 million.
If the derivative  instruments  had been  terminated at December 31, 2002,  this
estimated fair value represents the amount we would pay to the counterparties.

Equity Price Risk

     We maintain  trust funds,  as required by the NRC, to fund certain costs of
decommissioning our nuclear plants. As of December 31, 2002, our decommissioning
trust funds are reflected at fair value on our 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  us 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.  We actively
monitor the investment  performance of the trust funds and  periodically  review
asset  allocation  in  accordance  with our nuclear  decommissioning  trust fund
investment policy. A hypothetical 10% increase in interest rates and decrease in
equity prices would result in a $172 million  reduction in the fair value of the
trust  assets.  See Defined  Benefit  Pension and Other  Postretirement  Welfare

New Accounting Pronouncements

     In 2001,  the FASB issued SFAS No. 143.  SFAS No. 143  provides  accounting
requirements  for retirement  obligations  associated  with tangible  long-lived
assets.  We will adopt SFAS No. 143 on January 1, 2003.  Retirement  obligations
associated with long-lived  assets included within the scope of SFAS No. 143 are
those for which there is a legal  obligation to settle under existing or enacted
law,  statute,  written  or oral  contract  or by legal  construction  under the
doctrine  of  promissory  estoppel.  Adoption  of SFAS No.  143 will  change the
accounting for the  decommissioning  of our nuclear generating plants as well as
certain other long-lived  assets. We are in the process of evaluating the impact
of adopting SFAS No. 143 on our financial condition.
     As it  relates  to  nuclear  decommissioning,  the  effect of a  cumulative
adjustment will be to decrease the decommissioning liability to reflect the fair
value of the decommissioning obligation at the balance sheet date. Additionally,
SFAS  No.  143  will  require  the  recognition  of  an  asset  related  to  the
decommissioning obligation,  which will be amortized over the remaining lives of
the plants.  The net difference,  between the asset recognized and the change in
the liability to reflect fair value recorded upon adoption of SFAS No. 143, will
be recorded in earnings and  recognized  as a  cumulative  effect of a change in
accounting principle,  net of expected regulatory recovery and income taxes. The
decommissioning   liability   will then represent an obligation for  the  future
decommissioning  of the  plants  and,  as a result,  accretion  expense  will be
accrued on this liability until the obligation is satisfied.
     Currently,  Generation records the obligation for  decommissioning  ratably
over  the  lives  of the  plants.  Based  on the  current  information  and  the
credit-adjusted  risk-free  rate,  we estimate  the  increase  in 2003  non-cash
expense  to  impact  earnings  before  the  cumulative  effect  of a  change  in
accounting  principle  for the  adoption  of SFAS No. 143 by  approximately  $24
million,  after  income  taxes.  Additionally,  the  adoption of SFAS No. 143 is
expected to result in a large, non-cash,  one-time cumulative effect of a change
in accounting  principle gain of at least $1.5 billion,  after income taxes. The
$1.5 billion gain and the $24 million charge includes our share of the impact of
the SFAS No. 143 adoption related to AmerGen's nuclear plants. These impacts are
based on our current interpretation of SFAS No. 143 and are subject to continued
refinement  based on the finalization of assumptions and  interpretation  at the
time  of  adopting   the   standard,   including   the   determination   of  the
credit-adjusted  risk-free  rate.  Under  SFAS No.  143,  the fair  value of the
nuclear  decommissioning  obligation  will continue to be adjusted on an ongoing
basis as these model input factors change.
     The final  determination  of the 2003  earnings  impact and the  cumulative
effect of  adopting  SFAS No. 143 is in part a function  of the credit  adjusted
risk-free  rate at the  time of the  adoption  of SFAS  No.  143.  Additionally,
although over the life of the plant the charges to earnings for the depreciation
of the asset and the interest on the liability will be equal to the amounts that
would have been recognized as decommissioning  expense under current accounting,
the timing of those charges will change and in the near-term  period  subsequent
to adoption,  the depreciation of the asset and the interest on the liability is
expected to result in an increase in expense.
     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.
     In November  2002,  the FASB  released  FASB  Interpretation  No. (FIN) 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

                                       72


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.  As of December 31, 2002,  we have  adopted  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 are effective,  on a prospective basis, for guarantees issued or modified
after December 31, 2002.
     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 46 on our
consolidated  financial position,  results of operations and cash flows, has not
been fully determined.
