Notes to Consolidated Financial Statements
- ------------------------------------------

Weather  conditions can have a great impact on our results for interim  periods.
This means that results for interim periods do not necessarily represent results
to be expected for the year.

Our interim  financial  statements on the previous pages reflect all adjustments
that  Management  believes  are  necessary  for  the  fair  presentation  of the
financial  position and results of operations for the interim periods presented.
These adjustments are of a normal recurring nature.

Holding Company Formation
- -------------------------
On April 30, 1999,  Constellation Energy (R) Group, Inc.  (Constellation Energy)
became the holding company for Baltimore Gas and Electric  Company  (BGE(R)) and
Constellation(R)  Enterprises,  Inc.  Constellation  Enterprises  was previously
owned by BGE.  BGE's  outstanding  common stock  automatically  became shares of
common  stock  of  Constellation   Energy.  BGE's  debt  securities,   obligated
mandatorily  redeemable trust preferred securities,  and preference stock remain
securities of BGE.


Basis of Presentation
- ---------------------
This Quarterly Report on Form 10-Q is a combined report of Constellation  Energy
and BGE. The consolidated  financial  statements of Constellation Energy include
the accounts of Constellation  Energy,  BGE and its subsidiaries,  Constellation
Enterprises,  Inc. and its subsidiaries,  and Constellation Nuclear, LLC and its
subsidiaries.  The consolidated financial statements of BGE include the accounts
of BGE,  District  Chilled  Water  General  Partnership  (ComfortLink),  and BGE
Capital  Trust  I.  As  Constellation  Enterprises  and  its  subsidiaries  were
subsidiaries  of  BGE  prior  to  April  30,  1999,  they  are  included  in the
consolidated financial statements of BGE through that date.

References in this report to "we" and "our" are to Constellation  Energy and its
subsidiaries,  collectively.  Reference in this report to the "utility business"
is to BGE.

Deregulation of Electric Generation
- -----------------------------------
On April 8, 1999, Maryland enacted legislation  authorizing  customer choice and
competition  among electric  suppliers.  In addition,  on November 10, 1999, the
Maryland Public Service Commission  (Maryland PSC) issued a Restructuring  Order
that resolved the major issues  surrounding  electric  restructuring.  Effective
July 1, 2000,  the state of Maryland  implemented  customer  choice for electric
suppliers.  We discuss the implications of customer choice and the Restructuring
Order  further in  Management's  Discussion  and Analysis  beginning on page 17.
Please also refer to the Legal  Proceedings  section on page 35 for a discussion
regarding appeals of the Restructuring Order.

Information by Operating Segment
- --------------------------------
In 1999,  we reported  three  operating  segments --  Electric,  Gas, and Energy
Services.  In response to the deregulation of electric generation,  we realigned
our  organization  and combined our wholesale power marketing  business with our
domestic plant development and operations to form a merchant energy business.

In 2000, we revised our operating  segments to reflect the  realignments  of our
organization.  Our new reportable  operating segments are -- Regulated Electric,
Regulated Gas, and Domestic Wholesale Energy:

o    Our regulated electric business generates, purchases, and sells electricity
     in a regulated environment,
o    Our regulated gas business purchases,  transports, and sells natural gas in
     a regulated environment, and
o    Our nonregulated domestic wholesale energy business:
      -  develops, owns, and operates domestic power
         projects,
      -  provides power marketing and risk management
         services, and
      -  provides nuclear consulting services.

                                       11



We have restated certain prior period information for comparative purposes based
on our new reportable operating segments.

The  financial  results of the electric  generation  portion of our business are
included in our regulated  electric  segment.  However,  after June 30, 2000, we
will  include the  financial  results of  electric  generation  in the  domestic
wholesale energy segment.

Our remaining nonregulated businesses:

o    develop, own, and operate international power projects,
o    provide energy products and services,
o    sell  and  service  electric  and  gas  appliances,  and  heating  and  air
     conditioning  systems,  engage in home  improvements,  and sell natural gas
     through mass marketing efforts,
o    provide cooling services,
o    engage in financial investments, and
o    develop, own and manage real estate and senior-living facilities.

Financing Activity
- ------------------

Constellation Energy
- --------------------
As discussed on page 11,  effective  April 30, 1999,  BGE's  outstanding  common
stock  automatically  became  shares of common  stock of  Constellation  Energy.
During the period  from  January 1, 2000  through  the date of this  report,  we
issued a total of 475,300 shares of common stock,  without par value,  under our
Continuous Offering Program for Stock. Net proceeds were about $16.8 million.

Constellation  Energy issued the following  medium-term  notes during the period
from January 1, 2000 through the date of this report:

                                           Date      Net
                              Principal   Issued  Proceeds
                              ----------------------------
                                       (In millions)

7 7/8% Notes due 2005           $300        4/00    $297.5
Floating Rate Notes due 2003     200        4/00     199.3
Extendible Notes due 2010        300        6/00     299.6

In June 2000,  Constellation  Energy  arranged two revolving  credit  agreements
totaling  $565  million to support our  commercial  paper  program and for other
working  capital  purposes.  Of this amount,  $376.5  million is for  short-term
financial needs and $188.5  million,  which expires in three years, is for short
and long-term  financial needs,  including  letters of credit. As of the date of
this report,  letters of credit  totaling  $40.9  million were issued under this
facility.  Also, letters of credit totaling $131 million were issued under other
credit facilities.

Constellation  Energy has issued  guarantees  in an amount up to $626.8  million
related  to credit  facilities  and  contractual  performance  of certain of its
nonregulated subsidiaries. However, the actual subsidiary liabilities related to
these guarantees totaled $408.8 million at June 30, 2000.

In the future,  Constellation  Energy may purchase some of its long-term debt in
the market.  This will depend on market  conditions and  Constellation  Energy's
capital structure.

BGE and Nonregulated Businesses
- -------------------------------
In June 2000, BGE arranged a $25 million long-term revolving credit agreement to
support its commercial paper program and for other working capital purposes.

In the future,  BGE may purchase some of its long-term debt or preference  stock
in the  market.  This  will  depend  on  market  conditions  and  BGE's  capital
structure, including the mix of secured and unsecured debt.

Please  refer to the Funding for Capital  Requirements  section of  Management's
Discussion and Analysis on page 33 for additional  information about the debt of
BGE and our nonregulated businesses.

Stock Option Program
- --------------------
In May 2000, our Board of Directors approved the issuance of non-qualified stock
options to officers  and key  employees as permitted  under  existing  incentive
plans.  Under the plans,  the  options  are  granted at prices not less than the
market value of the stock at the date of grant,  become exercisable ratably over
a three-year  period  beginning  one-year from the date of grant, and expire ten
years from the date of grant.  During the second quarter,  we granted  2,313,000
stock options at an exercise price of $34.25.

As  permitted  by SFAS No. 123,  Accounting  for  Stock-Based  Compensation,  we
measure our stock-based  compensation  in accordance with Accounting  Principles
Board  Opinion No. 25,  Accounting  for Stock Issued to  Employees,  and related
interpretations.  Under this standard,  compensation  expense is measured as the
difference  between the market value of our common stock and the exercise  price
of the  options on the grant  date.  Accordingly,  no  compensation  expense was
recorded for the stock options granted in 2000.

                                       13


Commitments
- -----------
Some of our  nonregulated  businesses  have  committed to contribute  additional
capital and to make additional  loans to some  affiliates,  joint ventures,  and
partnerships  in which they have an interest.  At the date of this  report,  the
total  amount  of  investment  requirements  committed  to by  our  nonregulated
businesses  was $219.2  million.  This  amount  includes  $19.5  million for our
domestic  wholesale  energy  business'  remaining   commitment  to  Orion  Power
Holdings, Inc. To date, our domestic wholesale energy business has funded $205.5
million in equity to Orion.

Environmental Matters
- ---------------------

Clean Air
- ---------
The Clean Air Act of 1990  contains two titles  designed to reduce  emissions of
sulfur  dioxide and nitrogen  oxide (NOx) from  electric  generating  stations -
Title IV and Title I.

Title IV addresses  emissions of sulfur  dioxide.  Compliance is required in two
phases:

o   Phase I became  effective  January 1, 1995. We met the  requirements of this
    phase by installing flue gas desulfurization  systems,  switching fuels, and
    retiring some units.
o   Phase  II  became   effective   January  1,  2000.  We  met  the  compliance
    requirements through a combination of switching fuels and allowance trading.

We will  meet the  ongoing  compliance  requirements  through a  combination  of
switching fuels and allowance trading.

Title I addresses  emissions of NOx. The Maryland  Department of the Environment
(MDE) issued  regulations,  effective October 18, 1999, which required up to 65%
NOx emissions  reductions by May 1, 2000. We entered into a settlement agreement
with the MDE  since we could  not meet  this  deadline.  Under  the terms of the
settlement  agreement,  BGE will install  emissions  reduction  equipment at two
sites by May 2002. In the meantime, we are taking steps to control NOx emissions
at our generating plants.

The Environmental  Protection Agency (EPA) issued a final rule in September 1998
that required up to 85% NOx emissions  reduction by 22 states including Maryland
and Pennsylvania. Maryland expects to meet the requirements of the rule by 2003.
The emissions reduction equipment installations discussed above will allow us to
meet these requirements.

We currently  estimate that the controls needed at our generating plants to meet
the MDE's 65% NOx emission  reduction  requirements will cost approximately $135
million.  Through  the date of this  report,  we have  spent  approximately  $68
million to meet the 65% reduction requirements.  We estimate the additional cost
for the EPA's 85% reduction  requirements to be approximately $35 million by the
end of 2002.

In July 1997, the EPA published new National  Ambient Air Quality  Standards for
very fine  particulates  and revised  standards for ozone  attainment.  In 1999,
these new standards were successfully  challenged in court. The EPA appealed the
1999 court rulings to the Supreme Court.  In May 2000, the Supreme Court decided
to hear the EPA's appeal.  While these standards may require increased  controls
at our fossil  generating  plants in the future,  implementation,  if  required,
would be  delayed  for  several  years.  We  cannot  estimate  the cost of these
increased  controls  at this time  because the states,  including  Maryland  and
Pennsylvania,  still need to determine  what  reductions in  pollutants  will be
necessary to meet the EPA standards.

Waste Disposal
- --------------
The EPA and several state  agencies  have  notified us that we are  considered a
potentially   responsible   party  with   respect  to  the  cleanup  of  certain
environmentally  contaminated  sites  owned and  operated  by others.  We cannot
estimate the cleanup costs for all of these sites.

We can,  however,  estimate  that our  current  15.43%  share of the  reasonably
possible  cleanup  costs at one of these sites,  Metal Bank of America,  a metal
reclaimer in Philadelphia,  could be as much as $4.9 million higher than amounts
we have  recorded  as a  liability  on our  Consolidated  Balance  Sheets.  This
estimate is based on a Record of Decision issued by the EPA.

On July 12, 1999, the EPA notified us, along with nineteen other entities,  that
we may be a  potentially  responsible  party at the 68th Street  Dump/Industrial
Enterprises  Site,  also  known as the Robb Tyler  Dump  located  in  Baltimore,
Maryland.  The EPA  indicated  that it is  proceeding  with  plans to  conduct a
remedial investigation and feasibility study. This site was proposed for listing
as a federal  Superfund  site in  January  1999,  but the  listing  has not been
finalized.  Although our  potential  liability  cannot be  estimated,  we do not
expect such  liability to be material  based on our records  showing that we did
not send waste to the site.

                                       14


Also,  we  are  coordinating  investigation  of  several  sites  where  gas  was
manufactured in the past. The  investigation  of these sites includes  reviewing
possible  actions to remove coal tar. In late December 1996, we signed a consent
order with the MDE that  requires  us to  implement  remedial  action  plans for
contamination  at and around  the Spring  Gardens  site,  located in  Baltimore,
Maryland. We submitted the required remedial action plans and they were approved
by the MDE.  Based on the  remedial  action  plans,  the costs we consider to be
probable to remedy the contamination are estimated to total $47 million. We have
recorded these costs as a liability on our Consolidated  Balance Sheets and have
deferred these costs,  net of accumulated  amortization and amounts we recovered
from insurance companies, as a regulatory asset. We discuss this further in Note
5 of our 1999 Annual  Report on Form 10-K.  Through the date of this report,  we
have spent approximately $35 million for remediation at this site.

We are also  required  by  accounting  rules  to  disclose  additional  costs we
consider to be less likely than  probable,  but still  "reasonably  possible" of
being incurred at these sites. Because of the results of studies at these sites,
it is reasonably possible that these additional costs could exceed the amount we
recognized by approximately $14 million.

We do not expect the  cleanup  costs of the  remaining  sites to have a material
effect on our financial results.

Our potential  environmental  liabilities and pending  environmental actions are
described  further in our 1999 Annual  Report on Form 10-K in Item 1. Business -
Environmental Matters.

Nuclear Insurance
- -----------------
If there were an accident  or an  extended  outage at either unit of the Calvert
Cliffs Nuclear Power Plant (Calvert Cliffs), it could have a substantial adverse
financial  effect on us. The  primary  contingencies  that would  result from an
incident at Calvert Cliffs could include:

o    physical damage to the plant,
o    recoverability of replacement power costs, and
o    our liability to third parties for property damage and bodily injury.

We have insurance policies that cover these contingencies, but the policies have
certain industry standard exclusions.  Furthermore,  the costs that could result
from a covered  major  accident  or a covered  extended  outage at either of the
Calvert Cliffs units could exceed our insurance coverage limits.

Insurance for Calvert Cliffs and Third Party Claims
- ---------------------------------------------------
For  physical  damage to  Calvert  Cliffs,  we have $2.75  billion  of  property
insurance from an industry mutual insurance  company.  If an outage at either of
the two units at Calvert Cliffs is caused by an insured physical damage loss and
lasts more than 12 weeks, we have insurance coverage for replacement power costs
up to $490.0 million per unit, provided by an industry mutual insurance company.
This amount can be reduced by up to $98.0  million per unit if an outage at both
units of the  plant is caused  by a single  insured  physical  damage  loss.  If
accidents  at any  insured  plants  cause a shortfall  of funds at the  industry
mutual insurance company,  all policyholders  could be assessed,  with our share
being up to $15.4 million.

In addition  we, as well as others,  could be charged for a portion of any third
party claims associated with a nuclear incident at any commercial  nuclear power
plant in the  country.  At the date of this  report,  the limit for third  party
claims from a nuclear  incident is $9.54  billion  under the  provisions  of the
Price  Anderson  Act. If third party  claims  exceed $200 million (the amount of
primary  insurance),  our share of the total  liability  for third party  claims
could be up to $176.2  million per  incident.  That amount would be payable at a
rate of $20 million per year.

Insurance for Worker Radiation Claims
- -------------------------------------
As an operator of a commercial  nuclear power plant in the United States, we are
required to  purchase  insurance  to cover  radiation  injury  claims of certain
nuclear workers. On January 1, 1998, a new insurance policy became effective for
all operators  requiring coverage for current  operations.  Waiving the right to
make additional claims under the old policy was a condition for acceptance under
the new policy. We describe both the old and new policies below.

o  Nuclear  worker claims  reported on or after January 1, 1998 are covered by a
   new insurance policy with an annual industry  aggregate limit of $200 million
   for radiation injury claims against all those insured by this policy.

o  All nuclear worker claims reported prior to January 1, 1998 are still covered
   by the old  insurance  policies.  Insureds  under the old  policies,  with no
   current  operations,  are not required to purchase  the new policy  described
   above,  and may still make claims against the old policies for the next eight
   years. If radiation  injury claims under these old policies exceed the policy
   reserves,  all  policyholders  could be assessed,  with our share being up to
   $6.3 million.

                                       15


If claims under these polices exceed the coverage limits,  the provisions of the
Price Anderson Act (discussed in this section) would apply.

Recoverability of Electric Fuel Costs
- -------------------------------------
Under the terms of the Restructuring  Order, BGE's electric fuel rate clause was
discontinued  effective July 1, 2000.  Any  accumulated  difference  between our
actual costs of fuel and energy and the amounts  collected from customers  under
the electric fuel rate clause  through June 30, 2000 would be collected from our
customers  within a twelve month period as  determined  by the Maryland  PSC. At
June 30, 2000, the accumulated difference was $54.6 million.

We discuss the Maryland  PSC's  process for  evaluating  the  recoverability  of
electric fuel costs in Note 10 of our 1999 Annual Report on Form 10-K.

California Power Purchase Agreements
- ------------------------------------
Constellation Power, Inc. and subsidiaries and Constellation  Investments,  Inc.
(whose power  projects are managed by  Constellation  Power) have $294.7 million
invested in 14 projects that sell electricity in California under power purchase
agreements  called  "Interim  Standard  Offer No.  4"  agreements.  Under  these
agreements, the projects supply electricity to utility companies at:

o    a fixed  rate  for  capacity  and  energy  for the  first  10  years of the
     agreements, and
o    a fixed  rate for  capacity  plus a variable  rate for energy  based on the
     utilities' avoided cost for the remaining term of the agreements.

Generally,  a "capacity  rate" is paid to a power plant for its  availability to
supply  electricity,  and an "energy rate" is paid for the electricity  actually
generated.  "Avoided  cost"  generally  is  the  cost  of a  utility's  cheapest
next-available source of generation to service the demands on its system.

We use the term  "transitioned"  to describe when the 10-year  periods for fixed
energy  rates have  expired for these power  generation  projects and they began
supplying  electricity at variable rates. The three remaining projects that have
not transitioned will do so by December 2000.

The projects  that have already  transitioned  to variable  rates have had lower
revenues  under  variable  rates  than  they did  under  fixed  rates.  Once the
remaining  projects have  transitioned to variable rates, we expect the revenues
from those projects also to be lower than they are under fixed rates.

We discuss  the  earnings  for these  projects  in the  Nonregulated  Businesses
section of Management's Discussion and Analysis on page 29.

Other Nonregulated Businesses
- -----------------------------
We  discuss  our  other  nonregulated  businesses'  activities  further  in  the
Nonregulated  Businesses section of Management's Discussion and Analysis on page

Item 2. Management's Discussion

Management's  Discussion  and  Analysis of  Financial  Condition  and Results of
Operations

Introduction
- ------------
On April 30, 1999,  Constellation  Energy(R) Group, Inc.  (Constellation Energy)
became the holding company for Baltimore Gas and Electric  Company  (BGE(R)) and
Constellation(R)  Enterprises,  Inc.  Constellation  Enterprises  was previously
owned by BGE.

In response  to the  deregulation  of  electric  generation,  we  realigned  our
organization  and combined  our  wholesale  power  marketing  business  with our
domestic plant development and operations to form a merchant energy business. In
2000,  we revised our  operating  segments to reflect  the  realignments  of our
organization,  as presented in the Notes to Consolidated Financial Statements on
page 11.

Constellation  Energy's  subsidiaries  primarily  include  BGE  and  a  domestic
wholesale  energy  business  focused  mostly  on power  marketing  and  merchant
generation in North America.

BGE is a  regulated  electric  and gas  public  utility  company  with a service
territory  in the City of  Baltimore  and all or part of ten counties in Central
Maryland.

Our domestic wholesale energy segment includes the:

o    wholesale power marketing of Constellation Power Source,(TM)Inc.,
o    domestic power projects of Constellation Power,  (TM)Inc., and subsidiaries
     and Constellation Investments,(TM) Inc., and
o    nuclear consulting services of Constellation Nuclear,(TM)LLC.

Through June 30, 2000, the financial results of the electric  generation portion
of our business are included in BGE's  regulated  electric  segment.  After that
date,  we will  include  the  financial  results of electric  generation  in the
domestic wholesale energy segment.

Our remaining nonregulated businesses include the:

o    international power projects of Constellation Power, and subsidiaries,
o    energy products and services of Constellation Energy Source,(TM)Inc.,
o    home products,  commercial building systems, and residential and commercial
     gas  retail  marketing  of BGE  Home  Products  &  Services,(TM)  Inc.  and
     subsidiaries,
o    general  partnership,  in which BGE is a partner, of District Chilled Water
     General  Partnership  (ComfortLink(R))  that provides  cooling services for
     commercial customers in Baltimore,
o    financial investments of Constellation Investments, and
o    real  estate and  senior-living  facilities  of  Constellation  Real Estate
     Group,(TM)Inc.

As  a  result  of  the  deregulation  of  electric  generation,  we  formed  two
nonregulated subsidiaries that will be included in our domestic wholesale energy
segment -- Calvert  Cliffs  Nuclear Power Plant,  Inc. and  Constellation  Power
Source Generation,  Inc. Effective July 1, 2000, BGE transferred, at book value,
its generation assets and related liabilities to these entities.

Effective July 1, 2000, Calvert Cliffs Nuclear Power Plant, Inc. is a subsidiary
of Constellation Nuclear, LLC.

In  addition,  on July 1,  2000,  we  formed  a  nonregulated  holding  company,
Constellation Power Source Holdings, Inc., that includes:

o    our wholesale power marketing of Constellation Power Source,
o    our domestic power projects of  Constellation  Power and  subsidiaries  and
     Constellation Investments, and
o    the newly formed Constellation Power Source Generation subsidiary.

This Quarterly Report on Form 10-Q is a combined report of Constellation  Energy
and BGE. The consolidated  financial  statements of Constellation Energy include
the accounts of Constellation  Energy,  BGE and its subsidiaries,  Constellation
Enterprises,  Inc. and its subsidiaries,  and Constellation Nuclear, LLC and its
subsidiaries.  The consolidated financial statements of BGE include the accounts
of BGE, ComfortLink,  and BGE Capital Trust I. As Constellation  Enterprises and
its  subsidiaries  were  subsidiaries  of BGE prior to April 30, 1999,  they are
included in the consolidated financial statements of BGE through that date.

                                       17


References in this report to "we" and "our" are to Constellation  Energy and its
subsidiaries,  collectively.  Reference in this report to the "utility business"
is to BGE.

In this discussion and analysis,  we explain the general financial condition and
the results of operations for Constellation Energy and BGE including:

o    what factors affect our business,
o    what our earnings and costs were in the periods presented,
o    why earnings and costs changed between periods,
o    where our earnings came from,
o    how all of this affects our overall financial condition,
o    what we expect our  expenditures  for capital projects to be in the future,
     and
o    where we expect to get cash for future capital expenditures.

As you read this discussion and analysis,  refer to our Consolidated  Statements
of Income  on page 3,  which  present  the  results  of our  operations  for the
quarters and six months ended June 30, 2000 and 1999. We analyze and explain the
differences  between  periods in the  specific  line  items of the  Consolidated
Statements of Income.  Our analysis is important in making  decisions about your
investments in Constellation Energy and/or BGE.

Also,  this  discussion  and analysis is based on the  operation of the electric
generation  portion of our utility business under rate regulation.  Our electric
business is currently  changing as we have  transferred our electric  generation
assets and related  liabilities to nonregulated  subsidiaries  of  Constellation
Energy and we have entered into retail customer  choice for electric  generation
effective  July 1, 2000.  Accordingly,  the results of operations  and financial
condition  described  in  this  discussion  and  analysis  are  not  necessarily
indicative of future performance.

Strategy
- --------
The change toward customer  choice will  significantly  impact our business.  In
response to this change, we regularly  evaluate our strategies with two goals in
mind:  to improve  our  competitive  position,  and to  anticipate  and adapt to
regulatory change.  Currently, the majority of our earnings are from BGE. In the
future,  we expect to derive almost  two-thirds of our earnings from competitive
markets that are not limited by franchise boundaries.

While BGE will continue to be regulated and deliver  electricity and natural gas
through its core  distribution  business,  our growth  strategies  center on the
nonregulated  domestic  wholesale  energy market with the objective of providing
new sources of earnings.  As a result of our  concentration on domestic merchant
energy, we decided to exit the international portion of our business in 1999. We
expect to complete our exit strategy by the end of 2000.

In addition, we might consider one or more of the following strategies:

o    the complete or partial  separation of our  transmission  and  distribution
     functions,
o    the construction, purchase, or sale of generation assets,
o    mergers or acquisitions of utility or non-utility businesses, and
o    spin-off or sale of one or more businesses.

We cannot  predict  whether any of the strategies  described  above may actually
occur,  or what their effect on our financial  results or  competitive  position
might be. However, with the shift toward customer choice,  competition,  and the
growth  of our  nonregulated  subsidiaries,  various  factors  will  affect  our
financial results in the future.  These factors include, but are not limited to,
operating our generation assets in a deregulated market without the benefit of a
fuel rate  adjustment  clause,  the loss of revenues due to  customers  choosing
alternative  suppliers,  higher  volatility  of  earnings  and cash  flows,  and
increased financial requirements of our nonregulated subsidiaries.  Please refer
to the Forward-Looking Statements section on page 37 for additional factors.

Also,  these  results will not be indicative  of the future  performance  of BGE
since BGE  transferred all of its generation  assets and related  liabilities to
nonregulated  subsidiaries of  Constellation  Energy effective July 1, 2000. The
impact of such transfer on BGE's financial  results will be material.  The total
assets,  liabilities,  and common  shareholders'  equity of Constellation Energy
will not change as a result of the transfer.

                                       18


Current Issues
- --------------

Competition - Electric
- ----------------------
Electric utilities are facing competition on various fronts, including:

o    the   construction  of  generating  units  to  meet  increased  demand  for
     electricity,
o    the sale of electricity in bulk power markets,
o    competing with alternative energy suppliers, and
o    electric sales to retail customers.

On April 8, 1999, Maryland enacted legislation  authorizing  customer choice and
competition  among electric  suppliers.  In addition,  on November 10, 1999, the
Maryland  PSC  issued a  Restructuring  Order  that  resolved  the major  issues
surrounding  electric  restructuring.  Effective  July 1,  2000,  the  state  of
Maryland implemented  customer choice for electric suppliers.  These matters are
discussed  further in this  section and in Note 4 of our 1999  Annual  Report on
Form 10-K.

As a result of the deregulation of BGE's electric  generation and effective July
1, 2000, the following occurred:

o    BGE transferred,  at book value, its nuclear generating assets, its nuclear
     decommissioning  trust fund,  and  related  liabilities  to Calvert  Cliffs
     Nuclear Power Plant, Inc. In addition, BGE transferred,  at book value, its
     fossil generating assets and related  liabilities and its partial ownership
     interest  in  two  coal  plants  and  a  hydroelectric   plant  located  in
     Pennsylvania to Constellation Power Source Generation, Inc. In total, these
     generating  assets  represent about 6,240 megawatts of generation  capacity
     with a total net book value at June 30, 2000 of approximately $2.4 billion.
o    BGE transferred  approximately  $47 million to Calvert Cliffs Nuclear Power
     Plant, Inc. and $231 million to Constellation Power Source Generation, Inc.
     of tax-exempt debt related to the transferred assets.  Also,  Constellation
     Power  Source  Generation,   Inc.  issued  approximately  $366  million  in
     unsecured promissory notes to BGE. Repayments of the notes by Constellation
     Power  Source  Generation,  Inc.  will be used  exclusively  to service the
     current maturities of certain BGE long-term debt.
o    BGE transferred  equity  associated  with the generating  assets to Calvert
     Cliffs Nuclear Power Plant, Inc. and Constellation Power Source Generation,
     Inc.
o    The fossil fuel and nuclear fuel inventories,  materials and supplies,  and
     certain  purchased  power  contracts  of BGE  were  also  assumed  by these
     subsidiaries.

We  present  pro-forma  financial  statements  for  BGE as an  exhibit  to  this
Quarterly  Report on Form 10-Q (Exhibit 99). The information  provided above and
in the  pro-forma  financial  statements  have been prepared  using  information
available at the date of this report.

Effective July 1, 2000, BGE will provide  standard offer service to customers at
fixed rates over  various time periods  during the  transition  period for those
customers that do not choose an alternate  supplier.  In addition,  the electric
fuel rate was discontinued  effective July 1, 2000.  Constellation  Power Source
will  provide BGE with the energy and  capacity  required  to meet its  standard
offer service  obligations  for the first three years of the transition  period.
Thereafter, BGE will competitively bid the energy and capacity.

Constellation  Power  Source will obtain the energy and capacity to supply BGE's
standard  offer service  obligations  from  affiliates  that own Calvert  Cliffs
Nuclear  Power Plant  (Calvert  Cliffs) and BGE's former  fossil plants and from
purchased power contracts, supplemented with energy purchased from the wholesale
energy  market as  necessary.  Our earnings  will be exposed to the risks of the
competitive  wholesale electricity market to the extent that Constellation Power
Source has to purchase  energy  and/or  capacity to meet  obligations  to supply
power to BGE at market  prices or costs,  respectively,  which may  approach  or
exceed BGE's standard offer service rates.  If the price of obtaining  energy in
the  wholesale  market  exceeds the fixed  standard  offer  service  price,  our
earnings  would be adversely  affected.  We will also be affected by operational
risk,  that is, the risk that a  generating  plant is not  available  to produce
energy when the energy is  required.  Imbalances  in demand and supply can occur
not only because of plant outages, but also because of transmission constraints,
or extreme temperatures (hot or cold) causing demand to exceed available supply.

We cannot estimate the impact of the increased  financial risks  associated with
customer choice.  However, these financial risks could have a material impact on
our, and BGE's, financial results.

                                       19


Competition - Gas
- -----------------
Currently,  no  regulation  exists for the  wholesale  price of natural gas as a
commodity,  and the regulation of interstate  transmission  at the federal level
has been  reduced.  All BGE gas  customers  have the option to purchase gas from
other suppliers.

Early Retirement Program
- ------------------------
In  recognition  of the  changing  business  environment,  in 1999 our  Board of
Directors  approved  a  Targeted  Voluntary  Special  Early  Retirement  Program
(TVSERP) to provide  enhanced  early  retirement  benefits  to certain  eligible
participants  in  targeted  jobs that  elected  to retire on June 1,  2000.  BGE
recorded  approximately  $10.0 million for employees that elected to participate
in the program.  Of this amount, BGE recorded  approximately $3.0 million on its
balance sheet as a regulatory  asset of its gas business.  We will amortize this
regulatory  asset over a 5-year period as provided by the June 2000 Maryland PSC
gas base rate  order.  The  remaining  $7.0  million  related to BGE's  electric
business and was charged to expense.  We discuss the gas base rate order further
in the  Regulation by the Maryland PSC section on page 23. We discuss the impact
of the TVSERP on our financial  results in the Results of Operations  section on
page 26.


Calvert Cliffs License Extension
- --------------------------------
On March 23, 2000, the NRC approved a 20-year  license  extension for both units
of Calvert  Cliffs,  extending  the license for Unit 1 to 2034 and for Unit 2 to
2036.

On April 11,  2000 the  United  States  Court of  Appeals  for the  District  of
Columbia  Circuit,  in  National  Whistleblowers  Center v.  Nuclear  Regulatory
Commission  and Baltimore Gas and Electric  Company,  upheld the NRC's denial of
the Center's  motion to intervene in BGE's license renewal  proceeding.  The NRC
had  denied  the  Center's  motion  to  intervene  for  failing  to file  timely
contentions.


Regional Transmission Organizations
- -----------------------------------
In December 1999, the FERC issued Order 2000, amending its regulations under the
Federal   Power  Act  to  advance  the   formation   of  Regional   Transmission
Organizations  (RTOs).  The  regulations  require that each public  utility that
owns,  operates,  or controls facilities for the transmission of electric energy
in  interstate  commerce  make  certain  filings  with  respect to  forming  and
participating  in a RTO. FERC also  identified the minimum  characteristics  and
functions  that a  transmission  entity must satisfy in order to be considered a
RTO.

According  to the  Order,  a  public  utility  that is a member  of an  existing
transmission  entity that has been approved by FERC as in  conformance  with the
Independent  System  Operator  (ISO)  principles set forth in the FERC Order No.
888,  such  as  BGE,  through  its  membership  in  the  PJM   (Pennsylvania-New
Jersey-Maryland)  Interconnection,  must make a filing no later than January 15,
2001.  That filing must explain the extent to which the  transmission  entity in
which it participates meets the minimum  characteristics and functions of a RTO,
and either propose to modify the existing institution to the extent necessary to
become a RTO,  or explain  the  efforts,  obstacles,  and plans with  respect to
conforming to these characteristics and functions.

As a member of the PJM, an existing  ISO,  BGE does not expect to be  materially
impacted by the Order.  However,  BGE,  along with other  members of the PJM, is
appealing  certain aspects of the Order. We cannot  determine the full impact of
the Order at this time.

Quarter Ended June 30, 2000
- ---------------------------
Our total earnings for the quarter ended June 30, 2000 decreased  $28.4 million,
or $.19 per  share,  compared  to the same  period of 1999.  Our total  earnings
decreased  because  we had lower  earnings  from our  utility  and  nonregulated
businesses before nonrecurring charges. In addition, we recorded the following:

o   a $24.0 million, or $15.0 million after-tax, deregulation transition cost to
    a third party  incurred  by our power  marketing  business to provide  BGE's
    standard offer service requirements, and
o   a $2.8 million,  or $1.7 million  after-tax,  expense for BGE employees that
    elected to  participate  in a Targeted  Voluntary  Special Early  Retirement
    Program (TVSERP) during the second quarter of 2000.

In the second quarter of 2000,  utility  earnings  before  nonrecurring  charges
decreased  compared to the same period of 1999 mostly due to the $37.5  million,
or $22.7 million  after-tax,  amortization of the regulatory  asset recorded for
the reduction of BGE's generation plant as provided for under the  Restructuring
Order. This was partially offset by higher electric and gas sales.

We discuss our utility earnings, the Restructuring Order, and the TVSERP in more
detail in the Utility Business section on page 22.

In the second quarter of 2000, nonregulated earnings before nonrecurring charges
decreased  compared to the same period of 1999 mostly  because of lower earnings
from our financial investments and international  businesses.  Earnings from our
domestic  wholesale  energy  business  were about the same  compared to the same
period of 1999.  We  discuss  our  nonregulated  earnings  and the  deregulation
transition cost in more detail in the Nonregulated  Businesses section beginning
on page 28.

Six Months Ended June 30, 2000
- ------------------------------
Our total  earnings  for the six months  ended  June 30,  2000  decreased  $39.1
million,  or $.26 per  share,  compared  to the same  period of 1999.  Our total
earnings   decreased  because  we  had  lower  earnings  from  our  utility  and
nonregulated  businesses before nonrecurring  charges. In addition,  we recorded
the following:

o    a $24.0 million, or $15.0 million after-tax,  deregulation  transition cost
     to a third party incurred by our power marketing  business to provide BGE's
     standard offer service requirements, and
o    a $7.0 million,  or $4.2 million after-tax,  expense for BGE employees that
     elected to participate in the TVSERP.

In the six months  ended June 30, 2000,  utility  earnings  before  nonrecurring
charges  decreased  compared  to the same period of 1999 mostly due to the $75.0
million,  or $45.4  million  after-tax,  amortization  of the  regulatory  asset
recorded for the reduction of BGE's  generation  plant as provided for under the
Restructuring Order. This was partially offset by higher electric and gas sales.

In the six months ended June 30, 2000, nonregulated earnings before nonrecurring
charges  decreased  compared to the same period of 1999 mostly  because of lower
earnings from our  international  business.  This was partially offset by higher
earnings in our financial investments business and slightly higher earnings from
our domestic wholesale energy business.


                                       21


Utility Business
- ----------------
Before we go into the details of our electric and gas operations,  we believe it
is  important  to discuss  factors  that have a strong  influence on our utility
business performance:  electric  restructuring,  regulation by the Maryland PSC,
the weather,  and other  factors,  including the condition of the economy in our
service territory.

Electric Restructuring
- ----------------------
On April 8, 1999,  Maryland enacted the Electric Customer Choice and Competition
Act of 1999 (the "Act") and accompanying tax legislation that will significantly
restructure  Maryland's  electric utility industry and modify the industry's tax
structure.

In the Restructuring Order discussed below, the Maryland PSC addressed the major
provisions of the Act. The  accompanying  tax legislation is discussed in detail
in Note 4 of our 1999 Annual Report on Form 10-K.

On  November  10,  1999,  the  Maryland  PSC issued a  Restructuring  Order that
resolved the major issues surrounding  electric  restructuring,  accelerated the
timetable for customer  choice,  and addressed the major  provisions of the Act.
The  Restructuring  Order also  resolved the electric  restructuring  proceeding
(transition costs, customer price protections,  and unbundled rates for electric
services)  and a petition  filed in  September  1998 by the  Office of  People's
Counsel  (OPC) to lower our electric  base rates.  The major  provisions  of the
Restructuring Order are discussed below.

o    All customers,  except a few commercial and industrial  companies that have
     signed  contracts  with BGE,  can choose  their  electric  energy  supplier
     beginning  July 1, 2000.  BGE will  provide a standard  offer  service  for
     customers that do not select an alternative  supplier.  In either case, BGE
     will   continue  to  deliver   electricity   to  all   customers  in  areas
     traditionally served by BGE.
o    BGE's electric base rates were frozen through June 30, 2000.
o    BGE reduced  residential base rates by approximately 6.5%, on average about
     $54  million a year,  beginning  July 1, 2000.  These rates will not change
     before July 2006.
o    Commercial  and industrial  customers have up to four service  options that
     will fix  electric  energy rates and  transition  charges for a period that
     generally ranges from four to six years.
o    BGE's electric fuel rate clause was discontinued effective July 1, 2000.
o    Electric  delivery  service  rates are  frozen for a  four-year  period for
     commercial  and  industrial  customers.  The  generation  and  transmission
     components of rates are frozen for different time periods  depending on the
     service options selected by those customers.
o    BGE  will  recover  $528  million  after-tax  of its  potentially  stranded
     investments   and  utility   restructuring   costs  through  a  competitive
     transition charge on customers' bills.  Residential customers will pay this
     charge for six years.  Commercial  and  industrial  customers will pay in a
     lump sum or over the four to  six-year  period,  depending  on the  service
     option selected by each customer.
o    Generation-related  regulatory assets and nuclear decommissioning costs are
     included  in  delivery  service  rates  effective  July 1, 2000 and will be
     recovered on a basis  approximating  their amortization  schedules prior to
     July 1, 2000.
o    Effective July 1, 2000, BGE unbundled rates to show separate components for
     delivery service, transition charges, standard offer services (generation),
     transmission, universal service, and taxes.
o    Effective  July  1,  2000,  BGE   transferred,   at  book  value,  its  ten
     Maryland-based  fossil and nuclear  power plants and its partial  ownership
     interest in two coal plants and a  hydroelectric  plant in  Pennsylvania to
     nonregulated subsidiaries of Constellation Energy.
o    BGE reduced  its  generation  assets,  as  discussed  in Note 4 of our 1999
     Annual Report on Form 10-K, by $150 million  pre-tax during the period July
     1, 1999 - June 30, 2000 to mitigate a portion of BGE's potentially stranded
     investments.
o    Universal  service  will  be  provided  for  low-income  customers  without
     increasing  their  bills.  BGE will  provide its share of a statewide  fund
     totaling $34 million annually.

We believe  that the  Restructuring  Order  provided  sufficient  details of the
transition plan to competition for BGE's electric generation business to require
BGE  to  discontinue  the  application  of  Statement  of  Financial  Accounting
Standards  (SFAS)  No.  71,  Accounting  for the  Effects  of  Certain  Types of
Regulation for that portion of its business.  Accordingly, in the fourth quarter
of 1999,  we adopted the  provisions  of SFAS No. 101,  Regulated  Enterprises -
Accounting for the  Discontinuation of FASB Statement No. 71 and Emerging Issues
Task Force

                                       22


Consensus  (EITF) No. 97-4,  Deregulation of the Pricing of Electricity - Issues
Related to the  Application of FASB Statements No. 71 and 101 for BGE's electric
generation business.  BGE's transmission and distribution  business continues to
meet the  requirements  of SFAS No. 71 as that business  remains  regulated.  We
describe the effect of applying these  accounting  requirements in Note 4 of our
1999 Annual Report on Form 10-K.

Please  refer  to the  Legal  Proceedings  section  on page 35 for a  discussion
regarding appeals of the Restructuring Order.

Regulation by the Maryland PSC
- ------------------------------
Under  traditional  rate  regulation that continues after July 1, 2000 for BGE's
electric  transmission and  distribution,  and gas businesses,  the Maryland PSC
determines the rates we can charge our customers.  Currently,  our rates consist
of a "base rate," a "conservation surcharge," and a "fuel rate."

Base Rate
- ---------
The base rate is the rate the Maryland PSC allows us to charge our customers for
the cost of providing them service, plus a profit. We have both an electric base
rate and a gas base rate.  Higher  electric  base rates apply  during the summer
when the demand for  electricity  is higher.  Gas base rates are not affected by
seasonal changes.

BGE may ask the  Maryland  PSC to  increase  base rates  from time to time.  The
Maryland  PSC  historically  has allowed  BGE to increase  base rates to recover
increased  utility  plant asset costs,  plus a profit,  beginning at the time of
replacement. Generally, rate increases improve our utility earnings because they
allow us to collect more revenue.  However,  rate increases are normally granted
based on  historical  data and those  increases  may not  always  keep pace with
increasing  costs.  Other parties may petition the Maryland PSC to decrease base
rates.

On November 17, 1999, BGE filed an application with the Maryland PSC to increase
its gas base rates. On June 19, 2000, the Maryland PSC authorized a $6.4 million
annual increase in our gas base rates effective June 22, 2000.

As a result of the Restructuring  Order, our residential electric base rates are
frozen until 2006.

Electric delivery service rates are frozen for a four-year period for commercial
and industrial  customers.  The generation and transmission  components of rates
are frozen for different time periods  depending on the service options selected
by those customers.

Conservation Surcharge
- ----------------------
The  Maryland  PSC allows us to include in electric and gas rates a component to
recover  money  spent on  conservation  programs.  This  component  is  called a
"conservation  surcharge." However, under this surcharge the Maryland PSC limits
what our profit can be. If, at the end of the year we have  exceeded our allowed
profit, we defer (include as a liability in our Consolidated  Balance Sheets and
exclude from our Consolidated  Statements of Income) the excess in that year and
we lower the amount of future  surcharges to our customers to correct the amount
of overage,  plus interest. As a result of the Restructuring Order, the electric
conservation  surcharge was frozen and the  associated  profit  limitation is no
longer applicable.

Fuel Rate
- ---------
Through June 30, 2000, we charged our electric customers separately for the fuel
we used to generate  electricity  (nuclear fuel,  coal, gas, or oil) and for the
net cost of purchases  and sales of  electricity.  We charged the actual cost of
these items to the  customer  with no profit to us. If these fuel costs went up,
the  Maryland PSC  permitted  us to increase the fuel rate.  If these costs went
down,  our customers  benefited from a reduction in the fuel rate. The fuel rate
was mostly  impacted by the amount of  electricity  generated at Calvert  Cliffs
because the cost of nuclear fuel is cheaper than coal, gas, or oil.

Under the Restructuring Order, BGE's electric fuel rate was frozen until July 1,
2000,  at which time the fuel rate  clause was  discontinued.  We  deferred  the
difference  between  our actual  costs of fuel and energy and what we  collected
from customers  under the fuel rate through June 30, 2000.  Currently,  earnings
are  affected  by the  changes in the cost of fuel and  energy.  We discuss  our
exposure to market risk  further in the  Current  Issues  section on page 19. In
addition, any accumulated difference between our actual costs of fuel and energy
and the amounts  collected  from  customers  under the electric fuel rate clause
through  June 30, 2000 would be  collected  from our  customers  within a twelve
month  period  as  determined  by the  Maryland  PSC.  At  June  30,  2000,  the
accumulated difference was $54.6 million.

We charge our gas  customers  separately  for the natural gas they purchase from
us. The price we charge for the  natural  gas is based on a market  based  rates
incentive  mechanism approved by the Maryland PSC. We discuss market based rates
in more detail in the Gas Cost  Adjustments  section on page 27 and in Note 1 of
our 1999 Annual Report on Form 10-K.

                                       23


Weather
- -------
Weather  affects the demand for  electricity  and gas. Very hot summers and very
cold winters  increase  demand.  Mild weather  reduces  demand.  Weather impacts
residential  sales more than commercial and industrial  sales,  which are mostly
affected by business needs for electricity and gas.

We  measure  the  weather's  effect  using  "degree  days." A degree  day is the
difference   between  the  average  daily  actual  temperature  and  a  baseline
temperature  of 65 degrees.  Cooling  degree days result when the average  daily
actual  temperature  exceeds the 65 degree baseline.  Heating degree days result
when the average daily actual temperature is less than the baseline.

During the cooling  season,  hotter  weather is measured by more cooling  degree
days and results in greater demand for electricity to operate  cooling  systems.
During the heating  season,  colder  weather is measured by more heating  degree
days and results in greater demand for  electricity  and gas to operate  heating
systems.

The  Maryland PSC allows us to record a monthly  adjustment  to our gas business
revenues to eliminate the effect of abnormal weather  patterns.  We discuss this
further in the Weather Normalization section on page 27.

We show the number of heating  degree days in the  quarter and six months  ended
June 30, 2000 and 1999, and the  percentage  change in the number of degree days
between these periods in the following table:

Other Factors
- -------------
Other factors,  aside from weather,  impact the demand for  electricity and gas.
These factors include the "number of customers" and "usage per customer"  during
a given period.  We use these terms later in our discussions of electric and gas
operations.  In those sections,  we discuss how these and other factors affected
electric and gas sales during the periods presented.

The number of customers in a given period is affected by new home and  apartment
construction and by the number of businesses in our service territory. Effective
July 1, 2000,  BGE's electric  customers can become delivery  service  customers
only and can  purchase  their  electricity  from other  sources.  The  remaining
electric  customers  will receive  standard  offer service from BGE at the fixed
rates  provided by the  Restructuring  Order.  Usage per customer  refers to all
other items impacting customer sales that cannot be measured  separately.  These
factors include the strength of the economy in our service  territory.  When the
economy is healthy and expanding, customers tend to consume more electricity and
gas.  Conversely,  during an economic  downtrend,  our customers tend to consume
less electricity and gas.

or $.04 per share compared to the same period of 1999. Our utility  earnings for
the six months ended June 30, 2000,  decreased $22.9 million,  or $.15 per share
compared  to the same six  months of 1999.  We  discuss  the  factors  affecting
utility earnings on page 25.

Regulated Electric Business
- ---------------------------
The discussion below reflects the operations of the electric  generation portion
of our utility  business under rate regulation by the Maryland PSC. As discussed
earlier in the Introduction and Current Issues sections,  retail customer choice
for electric generation began effective July 1, 2000. Implementation of customer
choice will significantly impact our business.

Electric System Sales Volumes
- -----------------------------
"Electric system sales volumes" are sales to customers in our service  territory
at rates set by the Maryland PSC. These sales do not include  interchange  sales
and sales to others.

The  percentage  changes  in our  electric  system  sales  volumes,  by  type of
customer, in 2000 compared to 1999 were:

                     Quarter Ended   Six Months Ended
                       June 30           June 30

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

Residential.......       8.5%             5.4%
Commercial........       8.5              6.0
Industrial........       1.3             (0.3)

During the quarter ended June 30, 2000, we sold more  electricity to residential
customers  due  to  warmer  spring  and  early  summer  weather.  We  sold  more
electricity  to commercial  customers  due to higher usage per customer,  warmer
weather,  and an increased  number of  customers.  We sold more  electricity  to
industrial  customers  mostly  because  usage by  Bethlehem  Steel (our  largest
customer)  increased  as a result of a 1999 shut down for a planned  upgrade  to
their facilities that temporarily reduced their electricity  consumption in that
year.

During  the six  months  ended  June  30,  2000,  we sold  more  electricity  to
residential  customers due to warmer spring and early summer  weather and higher
usage per customer.  We sold more  electricity  to  commercial  customers due to
higher usage per customer, warmer weather, and an increased number of customers.
We sold  about the same  amount of  electricity  to  industrial  customers.  The
increase  in  usage by  Bethlehem  Steel  was  offset  by  lower  usage by other
industrial customers.

Base Rates
- ----------
During the quarter and six months ended June 30, 2000,  base rate  revenues were
the same compared to the same periods of 1999.

Fuel Rates
- ----------
During the  quarter  and six  months  ended June 30,  2000,  fuel rate  revenues
increased  compared  to the same  periods  of 1999  mostly  because we sold more
electricity.

Interchange and Other Sales
- ---------------------------
"Interchange   and  other   sales"  are  sales  in  the  PJM   (Pennsylvania-New
Jersey-Maryland)  Interconnection energy market and to others. The PJM is an ISO
that also  operates  a  regional  power  pool with  members  that  include  many
wholesale market participants,  as well as BGE, and other utility companies.  We
sell energy to PJM members and to others after we have  satisfied the demand for
electricity in our own system.

During the quarter and six months ended June 30, 2000, we had lower  interchange
and  other  sales  compared  to the same  periods  of 1999  mostly  because  the
increased  demand for system sales reduced the amount of energy we had available
for off-system sales.

Actual Costs
- ------------
During the quarter and six months ended June 30, 2000,  our actual costs of fuel
to generate  electricity  (nuclear fuel,  coal,  gas, or oil) and electricity we
bought  from  others  were lower  compared  to the same  periods of 1999  mostly
because of lower purchased energy costs.

                                       25



Electric Fuel Rate Clause
- -------------------------
Under the  electric  fuel rate  clause,  we  deferred  (included  as an asset or
liability on the Consolidated  Balance Sheets and excluded from the Consolidated
Statements of Income) the difference between our actual costs of fuel and energy
and what we  collected  from  customers  under the fuel rate in a given  period.
Effective  July 1, 2000,  the  electric  fuel rate clause was  discontinued.  We
discuss  the  accumulated  difference  between  our  actual  costs  and  what we
collected through June 30, 2000 in the Fuel Rate section on page 23.

During the quarter and six months ended June 30, 2000,  our actual costs of fuel
and  energy  were  higher  than the fuel rate  revenues  we  collected  from our
customers.

Electric  Operations and Maintenance  Expenses
- ----------------------------------------------
During the quarter  ended June 30, 2000,  electric  operations  and  maintenance
expenses increased $4.9 million compared to 1999 mostly because we recorded $2.8
million of expense for electric  business  employees that elected to participate
in the TVSERP during the period.

During the six months ended June 30, 2000,  electric  operations and maintenance
expenses were about the same  compared to the same period of 1999.  During 2000,
we recorded $7.0 million of expense for electric business employees that elected
to  participate  in the TVSERP.  This was offset by higher  expenses in 1999 for
employee  benefit  costs and costs  related  to a major  winter  ice storm  that
increased expenses in that year.

Electric Depreciation and Amortization Expense
- ----------------------------------------------
During the quarter ended June 30, 2000,  electric  depreciation and amortization
expense  increased  $36.4 million  compared to 1999 mostly  because of the $37.5
million  amortization  of the  regulatory  asset for the reduction in generation
plant provided for in the Restructuring Order.

During  the  six  months  ended  June  30,  2000,   electric   depreciation  and
amortization  expense increased $76.0 million compared to 1999 mostly because of
the $75.0  million  amortization  of the  regulatory  asset for the reduction in
generation plant provided for in the Restructuring Order.

Regulated Gas Business
- ----------------------
All BGE customers have the option to purchase gas from other suppliers. To date,
customer  choice has not had a  material  effect on our,  and  BGE's,  financial
results.

Gas Revenues

Commercial................        7.5              5.2
Industrial................       13.2              4.5

During  the  quarter  ended  June 30,  2000,  we sold  more  gas to  residential
customers  compared  to the same  period of 1999 due to an  increased  number of
customers.  We sold more gas to commercial  customers  mostly  because of higher
usage per customer.  We sold more gas to  industrial  customers  mostly  because
usage by Bethlehem Steel (our largest  customer) and other industrial  customers
increased.  Usage by Bethlehem  Steel  increased as a result of a 1999 shut down
for a planned  upgrade to their  facilities that  temporarily  reduced their gas
consumption in that year. This was partially  offset by a decrease in the number
of customers.

During the six months ended June 30, 2000, we sold more gas to  residential  and
commercial customers compared to the same period of 1999 due to higher usage per
customer and an increased  number of  customers.  This was  partially  offset by
milder winter weather.  We sold more gas to industrial  customers mostly because
usage by Bethlehem  Steel and other  industrial  customers  increased.  This was
partially offset by a decrease in the number of customers.

                                       26


Base Rates
- ----------
During the quarter and six months ended June 30, 2000,  base rate  revenues were
about the same compared to the same periods of 1999.

On June 19, 2000, the Maryland PSC authorized a $6.4 million annual  increase in
our base rates effective June 22, 2000.

Weather Normalization
- ---------------------
The Maryland PSC allows us to record a monthly adjustment to our gas revenues to
eliminate  the effect of  abnormal  weather  patterns  on our gas  system  sales
volumes.  This means our  monthly  gas  revenues  are based on  weather  that is
considered  "normal"  for the month and,  therefore,  are not affected by actual
weather conditions.

Gas Cost Adjustments
- --------------------
We charge our gas  customers for the natural gas they purchase from us using gas
cost adjustment clauses set by the Maryland PSC. These clauses operate similarly
to the electric  fuel rate clause  described  in the  Electric  Fuel Rate Clause
section on page 26. However, under market based rates, our actual cost of gas is
compared  to a market  index (a measure  of the  market  price of gas in a given
period).  The difference  between our actual cost and the market index is shared
equally between  shareholders and customers,  and does not significantly  impact
earnings.

Delivery service  customers,  including  Bethlehem Steel, are not subject to the
gas cost  adjustment  clauses  because we are not selling gas to them. We charge
these customers fees to recover the fixed costs for the  transportation  service
we provide.  These fees are the same as the base rate  charged for gas sales and
are included in gas system sales volumes.

During the quarter ended June 30, 2000, gas cost adjustment  revenues were about
the same compared to the same period of 1999.

During  the six  months  ended  June  30,  2000,  gas cost  adjustment  revenues
decreased compared to the same period of 1999 mostly because we sold less gas to
non-delivery  service customers.  This was partially offset by a higher price of
gas sold.

Off-System Sales
- ----------------
Off-system gas sales are low-margin  direct sales of gas to wholesale  suppliers
of natural gas outside our service territory.  Off-system gas sales, which occur
after we have  satisfied  our  customers'  demand,  are not  subject to gas cost
adjustments.  The Maryland PSC  approved an  arrangement  for part of the margin
from  off-system  sales to benefit  customers  (through  reduced  costs) and the
remainder  to be  retained  by BGE  (which  benefits  shareholders).  Changes in
off-system sales do not significantly impact earnings.

During the quarter and six months ended June 30, 2000,  revenues from off-system
gas sales increased  compared to the same periods of 1999 mostly because we sold
more gas off-system at a higher price.

Actual Costs
- ------------
Actual costs  include the cost of gas  purchased for resale to our customers and
for off-system  sales.  Actual costs do not include the cost of gas purchased by
delivery service customers.

During  the  quarter  and six  months  ended  June 30,  2000,  actual  gas costs
increased compared to the same periods of 1999 mostly because we bought more gas
for off-system sales and all of the gas purchased was at a higher price.

Gas Adjustment Clauses
- ----------------------
We charge  customers  for the cost of gas sold  through gas  adjustment  clauses
(determined  by the  Maryland  PSC),  as  discussed  under Gas Cost  Adjustments
earlier in this section.

During the quarter and six months ended June 30, 2000, our actual gas costs were
higher than the fuel rate revenues we collected from our customers.

Gas Operations and Maintenance Expenses
- ---------------------------------------
During the  quarter  and six months  ended June 30,  2000,  gas  operations  and
maintenance expenses decreased slightly compared to the same periods of 1999.

Gas Depreciation and Amortization Expense
- -----------------------------------------
During the quarter and six months  ended June 30,  2000,  gas  depreciation  and
amortization expense was about the same compared to the same periods of 1999.

During  the  quarter  ended June 30,  2000,  earnings  from our power  marketing
business before  nonrecurring  charges decreased  compared to the same period of
1999  mostly  because  of  lower  margins,   and  increased  operating  expenses
associated with the growth of the business.

During the six months ended June 30,  2000,  earnings  from our power  marketing
business before  nonrecurring  charges  increased  slightly compared to the same
period of 1999 mostly because of increased transaction volumes, partially offset
by lower margins, and increased operating expenses associated with the growth of
the business.

As  discussed  in the Current  Issues  section on page 19,  Constellation  Power
Source  provides BGE with the energy and capacity  required to meet its standard
offer service  obligations  for the first three years of the  transition  period
effective July 1, 2000.

Constellation  Power  Source will obtain the energy and capacity to supply BGE's
standard offer service  obligations  from affiliates that own Calvert Cliffs and
BGE's former fossil plants and from purchased power contracts, supplemented with
energy  purchased  from the  wholesale  energy market as necessary and will also
manage our wholesale market price risk.

In June 2000,  Constellation  Power Source recognized a $15.0 million after-tax,
or $.10 per share,  deregulation  transition  cost to a third  party  related to
BGE's standard offer service requirements.

Constellation  Power Source uses the  mark-to-market  method of  accounting.  We
discuss the mark-to-market method of accounting and Constellation Power Source's
activities in more detail in Note 1 of our 1999 Annual Report on Form 10-K.

As a result  of the  nature  of its  business  activities,  Constellation  Power
Source's   revenue  and  earnings  will  fluctuate.   We  cannot  predict  these
fluctuations, but the effect on our revenues and earnings could be material. The
primary factors that cause these fluctuations are:

o    the number and size of new transactions,
o    the  magnitude and  volatility of changes in commodity  prices and interest
     rates, and
o    the  number  and  size  of  open   commodity   and   derivative   positions
     Constellation Power Source holds or sells.

                                       28



Constellation Power Source's management uses its best estimates to determine the
fair value of  commodity  and  derivative  positions  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.  However,  it is possible  that future  market  prices could vary from
those used in recording  assets and liabilities from power marketing and trading
activities,  and such variations could be material.  Assets and liabilities from
energy trading activities (as shown in our Consolidated Balance Sheets beginning
on page 4) increased  at June 30, 2000  compared to December 31, 1999 because of
business growth during the period.

Domestic Power Projects
- -----------------------
During  the  quarter  and six  months  ended June 30,  2000,  earnings  from our
domestic power projects business  increased compared to the same periods of 1999
mostly because our domestic power projects  business  recognized an $8.2 million
after-tax,  or  $.05  per  share,  gain  on  the  termination  of  an  operating
arrangement  and the sale of certain  subsidiaries.  This increase was partially
offset by lower earnings from our California  power purchase  agreements.  These
are discussed in further detail below.

In April 2000,  Constellation  Operating Services,  Inc. (COSI), a subsidiary of
Constellation  Power,  Inc.,  ended its exclusive  arrangement  with Orion Power
Holdings, Inc. to operate Orion's facilities. Orion purchased from COSI the four
subsidiary companies formed to operate power plants owned by Orion. As a result,
COSI  recognized  an $8.2 million  after-tax  gain during the second  quarter of
2000.

California Power Purchase Agreements
- ------------------------------------
Constellation  Power and subsidiaries and Constellation  Investments have $294.7
million  invested in 14 projects that sell electricity in California under power
purchase  agreements called "Interim Standard Offer No. 4" agreements.  Earnings
from these projects were $1.9 million,  or $.01 per share, for the quarter ended
June 30, 2000 compared to $5.9 million, or $.04 per share for the same period of
1999. Earnings from these projects were $8.8 million, or $.06 per share, for the
six months ended June 30, 2000 compared to $13.9 million,  or $.09 per share for
the same period of 1999.


Under  these  agreements,  the  electricity  rates  change  from fixed  rates to
variable rates beginning in 1996 and continuing through 2000. The projects which
already have had rate changes have lower revenues under variable rates than they
did under fixed rates. When the remaining projects transition to variable rates,
we expect their revenues also to be lower than they are under fixed rates.

At the date of this  report,  11 projects had already  transitioned  to variable
rates.  The remaining  three  projects will  transition in November and December
2000. Those projects  changing over later in 2000  contributed $3.6 million,  or
$.02 per share to the quarter ended June 30, 2000 earnings and $8.7 million,  or
$.06 per share to the six months ended June 30, 2000 earnings.

Our power projects business  continues to pursue  alternatives for some of these
projects including:

o    repowering the projects to reduce operating costs,
o    changing fuels to reduce operating costs,
o    renegotiating the power purchase agreements to improve the terms,
o    restructuring financing to improve existing terms, and
o    selling its ownership interests in the projects.

We  evaluate  the  carrying  amount  of our  investment  in these  projects  for
impairment  using the methodology  discussed in Note 1 of our 1999 Annual Report
of Form  10-K.  Constellation  Power's  management  uses its best  estimates  to
determine if there has been an  impairment  of these  investments  and considers
various  factors  including  forward  price curves for energy,  fuel costs,  and
operating costs.  However, it is possible that future estimates of market prices
and project costs could vary from those used in evaluating these assets, and the
impact of such variations could be material.

We also  describe  these  projects  and the  transition  process in the Notes to
Consolidated Financial Statements on page 16.

                                       29


Other Nonregulated Businesses
- -----------------------------
During the quarter  ended June 30, 2000,  earnings  from our other  nonregulated
businesses before nonrecurring  charges decreased compared to the same period of
1999  mostly  because  of lower  earnings  from our  financial  investments  and
international businesses.  Our financial investments business had lower earnings
due to a decline in its market performance,  and our international  business had
lower earnings primarily due to increased operating expenses in Guatemala.

During the six months ended June 30, 2000,  earnings from our other nonregulated
businesses before nonrecurring  charges decreased compared to the same period of
1999 mostly because of lower earnings from our international  business. This was
partially offset by higher earnings from our financial  investments business due
to better market performance of its investments.

In  December  1999,  we decided to exit the  international  portion of our power
projects  business as part of our strategy to improve our competitive  position.
We expect to  complete  our exit  strategy  by the end of 2000.  We discuss  our
strategy further in the Strategy section on page 18.

In June 1999, our financial  investments  business  wrote-down its $94.2 million
investment in Capital Re stock by $3.6 million  after-tax,  or $.02 per share to
reflect the  valuation for the exchange of its shares of common stock in Capital
Re for common stock of ACE Limited.  This  exchange is discussed  further in our
1999 Annual Report on Form 10-K.

Most of Constellation Real Estate Group's real estate and senior-living projects
are  in the  Baltimore-Washington  corridor.  The  area  has  had a  surplus  of
available  land in  recent  years  and as a  result  these  projects  have  been
economically hurt.

Constellation  Real Estate's projects have continued to incur carrying costs and
depreciation  over the years.  Additionally,  this  business  has been  charging
interest  payments to expense rather than capitalizing them for some undeveloped
land  where   development   activities  have  stopped.   These  carrying  costs,
depreciation,  and interest expenses have decreased earnings and are expected to
continue to do so.

Cash flow from real estate and  senior-living  operations has not been enough to
make the monthly loan payments on some of these  projects.  Cash shortfalls have
been covered by cash obtained  from the cash flows of, or additional  borrowings
by, other nonregulated subsidiaries.

We consider market demand,  interest rates, the  availability of financing,  and
the  strength of the economy in general  when  making  decisions  about our real
estate and senior-living projects. If we were to decide to sell our projects, we
could have  write-downs.  In  addition,  if we were to sell our  projects in the
current  market,  we would have losses  which could be  material,  although  the
amount of the losses is hard to  predict.  Depending  on market  conditions,  we
could also have material losses on any future sales.

Our current real estate and senior-living strategy is to hold each project until
we can  realize  a  reasonable  value for it.  Under  accounting  rules,  we are
required  to write down the value of a project to market  value in either of two
cases.  The first is if we change our intent  about a project  from an intent to
hold to an intent to sell and the  market  value of that  project  is below book
value. The second is if the expected cash flow from the project is less than the
investment in the project.

Consolidated Nonoperating Income and Expenses
- ---------------------------------------------

Fixed Charges
- -------------
During the quarter and six months ended June 30, 2000,  fixed charges  increased
compared  to  the  same  periods  of  1999  mostly  because  we  had  more  debt
outstanding.

Income Taxes
- ------------
During the  quarter  ended  June 30,  2000,  our total  income  taxes  decreased
compared to the same period of 1999 mostly  because we had lower taxable  income
partially  offset by a $7.0 million increase at BGE as a result of comprehensive
changes to the state and local tax laws.  We discuss the  comprehensive  tax law
changes in Note 4 of our 1999 Annual Report on Form 10-K.

During the six months  ended June 30, 2000,  our total  income  taxes  decreased
compared to the same period of 1999 mostly  because we had lower taxable  income
partially offset by a $17.3 million increase at BGE as a result of comprehensive
changes to the state and local tax laws.

   Financing Activities             169.5    (245.0)

During  the six  months  ended  June 30,  2000,  we  generated  less  cash  from
operations  compared  to the same  period in 1999  mostly  because of changes in
working capital requirements.

During  the six  months  ended June 30,  2000,  we used more cash for  investing
activities  compared  to the same  period in 1999  mostly due to an  increase in
investments in our domestic power projects business and Orion and an increase in
utility   construction   expenditures.   In   addition,   our  real  estate  and
senior-living facilities business received less cash compared to the same period
of 1999, due to the sale of a project in 1999. We did not have a similar sale in
2000.

During  the six  months  ended June 30,  2000,  we had more cash from  financing
activities  compared to the same  period of 1999  mostly  because we issued more
long-term  debt.  This was  partially  offset  by  repayment  of our  short-term
borrowings that matured.

Security Ratings
- ----------------
Independent   credit-rating   agencies  rate  Constellation   Energy  and  BGE's
fixed-income  securities.  The ratings indicate the agencies' assessment of each
company's ability to pay interest,  distributions,  dividends,  and principal on
these  securities.  These  ratings  affect how much it will cost each company to
sell  these  securities.  The  better  the  rating,  the  lower  the cost of the
securities to each company when they sell them.  Constellation  Energy and BGE's
securities ratings at the date of this report are:


                       Standard      Moody's     Duff & Phelps'

Capital Resources
- -----------------
Our business requires a great deal of capital.  Our estimated annual amounts for
the years 2000 through  2002,  are shown in the table on page 32. For the twelve
months  ended  June 30,  2000,  the  ratio of  earnings  to  fixed  charges  for
Constellation  Energy was 2.61.  The ratio of earnings to fixed  charges for BGE
was 3.40 and the ratio of earnings to combined  fixed  charges and preferred and
preference dividend requirements for BGE was 3.06.

We will continue to have cash requirements for:

o    working  capital needs  including the payments of interest,  distributions,
     and dividends,
o    capital expenditures, and
o    the retirement of debt and redemption of preference stock.

Capital  requirements  for 2000 through  2002  include  estimates of funding for
existing  and  anticipated  projects.  We  continuously  review and modify those
estimates. Actual requirements may vary from the estimates included in the table
on page 32 because of a number of factors including:

o    regulation, legislation, and competition,
o    BGE load requirements,
o    environmental protection standards,
o    the type and number of projects selected for development,
o    the effect of market conditions on those projects,
o    the cost and availability of capital, and
o    the availability of cash from operations.

Our  estimates  are  also  subject  to  additional   factors.   Please  see  the
Forward-Looking Statements section on page 37.

Effective  July 1, 2000,  all of BGE's  generation  assets were  transferred  to
nonregulated  subsidiaries of Constellation Energy. The discussion and table for
capital  requirements on page 32 include these generation  assets as part of the
utility's  regulated  electric  business through June 30, 2000. After that date,
the capital requirements are included in the domestic wholesale energy business.

* Effective  July 1, 2000,  includes  approximately  $110  million for  electric
generation and nuclear fuel formerly part of BGE's regulated electric business.

Capital Requirements
- --------------------
Electric Generation
- -------------------
Electric  construction  expenditures for our regulated  electric segment include
improvements to generating  plants and costs for replacing the steam  generators
at Calvert  Cliffs through June 30, 2000.  Thereafter,  these  expenditures  are
reflected in our domestic wholesale energy segment.

In March 2000, we received the license  extension  from the NRC that extends our
operating  licenses to 2034 for Unit 1 and 2036 for Unit 2 as  discussed  in the
Current Issues section on page 20. If we do not replace the steam generators, we
will not be able to operate these units through our operating  licenses  period.
We expect the steam  generator  replacement  to occur during the 2002  refueling
outage for Unit 1 and during the 2003  refueling  outage for Unit 2. We estimate
these Calvert Cliffs' costs to be:

o    $ 40 million in 2000,
o    $ 64 million in 2001,
o    $ 88 million in 2002, and
o    $ 60 million in 2003.

Additionally,   our  estimates  of  future  electric   generation   construction
expenditures include the costs of complying with Environmental Protection Agency
(EPA)  and  State  of  Maryland   nitrogen  oxides   emissions  (NOx)  reduction
regulations as follows:

o    $ 63 million in 2000,
o    $ 52 million in 2001, and
o    $ 4 million in 2002.

We discuss the NOx regulations  and timing of expenditures in the  Environmental
Matters section of the Notes to Consolidated Financial Statements on page 14.

Electric Transmission and Distribution, and Gas
- -----------------------------------------------
Regulated   electric   transmission  and  distribution,   and  gas  construction
expenditures  primarily include new business construction needs and improvements
to existing facilities.

                                       32


Domestic Wholesale Energy Business
- ----------------------------------
Our domestic  wholesale  energy  business  will require  additional  funding for
growing  its  power  marketing  business  and  developing  and  acquiring  power
projects.

Our domestic  wholesale  energy  business  investment  requirements  include the
planned   construction   of  1,100   megawatts   of  peaking   capacity  in  the
Mid-Atlantic/Mid-West  region  by the  summer  of 2001 and an  additional  4,300
megawatts of peaking and combined  cycle  production  facilities  scheduled  for
completion in 2002 and beyond in the Mid-West and South regions.

Our investment  requirements also include our domestic wholesale energy business
commitment to  contribute up to an additional  $19.5 million in equity to Orion.
To date,  our domestic  wholesale  energy  business has funded $205.5 million in
equity to Orion.

Funding for Capital Requirements
- --------------------------------

BGE
- ---
Our utility  business  has met its capital  requirements  in the past  primarily
through  internally  generated  funds.  When BGE could not meet utility  capital
requirements internally, BGE sold debt and preference stock.

BGE also sells securities when market conditions permit it to refinance existing
debt or  preference  stock at a lower  cost.  The  amount  of cash BGE needs and
market conditions determine when and how much BGE sells.

Future funding for capital  expenditures is expected from  internally  generated
funds,  commercial paper issuances,  available capacity under credit facilities,
the issuance of long-term debt, trust securities,  or preference  stock,  and/or
from time to time equity contributions from Constellation Energy.

At June 30, 2000,  FERC authorized BGE to issue up to $700 million of short-term
borrowings,  including commercial paper. In addition, BGE maintains $183 million
in annual  committed  bank lines of credit and has $60 million in bank revolving
credit agreements to support the commercial paper program. In addition,  BGE has
access to interim  lines of credit as required  from time to time to support its
outstanding commercial paper.

Domestic Wholesale Energy Business
- ----------------------------------
Our domestic  wholesale energy business has met its capital  requirements in the
past through borrowing,  cash from its operations,  and from time to time equity
contributions from BGE or Constellation Energy.

Future funding for the expansion of our domestic  wholesale  energy  business is
expected  from  internally  generated  funds,  commercial  paper  issuances  and
long-term debt financing by Constellation  Energy,  and from time to time equity
contributions from Constellation Energy.

At June 30, 2000,  Constellation  Energy has a commercial paper program where it
can  issue up to $500  million  in  short-term  notes  to fund its  nonregulated
businesses.  To support  its  commercial  paper  program,  Constellation  Energy
maintains two revolving credit  agreements  totaling $565 million,  of which one
facility can also issue letters of credit. In addition, Constellation Energy has
access to interim  lines of credit as required  from time to time to support its
outstanding commercial paper.

Other Nonregulated Businesses
- -----------------------------
BGE Home  Products & Services may meet  capital  requirements  through  sales of
receivables.  ComfortLink has a revolving credit agreement  totaling $50 million
to provide liquidity for short-term financial needs.

If we can get a  reasonable  value for our real estate  projects,  senior-living
facilities,  and other  investments,  additional cash may be obtained by selling
them. Our ability to sell or liquidate assets will depend on market  conditions,
and we cannot give assurances that these sales or liquidations could be made. We
discuss  the real  estate  and  senior-living  facilities  business  and  market
conditions in the Other Nonregulated Businesses section on page 30.

Other Matters
- -------------

Environmental Matters
- ---------------------
We are subject to federal,  state,  and local laws and regulations  that work to
improve or maintain the quality of the environment.  If certain  substances were
disposed of or released at any of our properties, whether currently operating or
not, these laws and regulations require us to remove or remedy the effect on the
environment.  This includes Environmental Protection Agency Superfund sites. You
will find  details of our  environmental  matters in the  Environmental  Matters
section of the Notes to Consolidated  Financial  Statements beginning on page 14
and in our 1999 Annual Report on Form 10-K in Item 1.  Business -  Environmental
Matters. These details include financial information. Some of the information is
about costs that may be material.

Accounting Standards Issued
- ---------------------------
In June 2000, the FASB issued Statement of Financial Accounting Standards (SFAS)
No. 138,  Accounting  for Certain  Derivative  Instruments  and Certain  Hedging
Activities,  that amends  certain  provisions  of SFAS No. 133,  Accounting  for
Derivative  Instruments and Hedging Activities and addresses a limited number of
implementation issues related to SFAS No. 133.

In July 1999,  the FASB issued SFAS No. 137 that delays the  effective  date for
SFAS No. 133 by one year.  Therefore,  we must adopt the  provisions of SFAS No.
133 in our financial statements for the quarter ended March 31, 2001.

We are  evaluating  the  implications  of SFAS  Nos.  133 and 138,  but have not
determined the effects on our financial results.  However, SFAS Nos. 133 and 138
will not significantly impact our power marketing business as this business uses
mark-to-market accounting.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

We discuss the following information related to our market risk:

o    risk  associated  with the  purchase  and sale of energy  in a  deregulated
     environment  as discussed  in the Current  Issues  section of  Management's
     Discussion and Analysis on page 19,
o    financing  activities in the Notes to Consolidated  Financial Statements on
     page 13, and
o    activities of our power marketing  business in the Power Marketing  section
     of Management's Discussion and Analysis on page 28.

PART II.  OTHER INFORMATION

Item 1.  Legal Proceedings
- --------------------------

Asbestos
- --------
Since 1993, we have been involved in several actions  concerning  asbestos.  The
actions are based upon the theory of "premises liability," alleging that we knew
of and exposed  individuals  to an asbestos  hazard.  The actions  relate to two
types of claims.

The first type is direct claims by individuals exposed to asbestos. We described
these claims in BGE's Report on Form 8-K filed August 20, 1993.  We are involved
in these  claims  with  approximately  70 other  defendants.  Approximately  530
individuals  that were never  employees  of BGE each claim $6 million in damages
($2 million  compensatory and $4 million  punitive).  These claims were filed in
the Circuit Court for Baltimore City,  Maryland in the summer of 1993. We do not
know the specific facts necessary to estimate our potential  liability for these
claims. The specific facts we do not know include:

o    the identity of our facilities at which the plaintiffs  allegedly worked as
     contractors,
o    the names of the plaintiff's employers, and
o    the date on which the exposure allegedly occurred.

To date, 25 of these cases were settled for amounts that were not significant.

The second type is claims by one  manufacturer  --  Pittsburgh  Corning Corp. --
against us and  approximately  eight others,  as third-party  defendants.  These
claims relate to approximately 1,500 individual plaintiffs and were filed in the
Circuit Court for Baltimore City,  Maryland in the fall of 1993. To date,  about
260 cases have been  resolved,  all without any  payments by BGE. We do not know
the  specific  facts  necessary to estimate our  potential  liability  for these
claims. The specific facts we do not know include:

o    the identity of our  facilities  containing  asbestos  manufactured  by the
     manufacturer,
o    the relationship (if any) of each of the individual plaintiffs to us,
o    the settlement amounts for any individual  plaintiffs who are shown to have
     had a relationship to us, and
o    the dates on which/places at which the exposure allegedly occurred.

Until the relevant facts for both types of claims are determined,  we are unable
to estimate what our liability,  if any, might be.  Although  insurance and hold
harmless  agreements  from  contractors  who employed the plaintiffs may cover a
portion of any awards in the actions, our potential liability could be material.

Restructuring Order
- -------------------
In early December  1999,  the  Mid-Atlantic  Power Supply  Association  (MAPSA),
Trigen-Baltimore  Energy  Corporation  and  Sweetheart  Cup Company,  Inc. filed
appeals of the  Restructuring  Order,  which were  consolidated in the Baltimore
City Circuit  Court.  MAPSA also filed a motion to delay  implementation  of the
Restructuring  Order,  pending a decision  on the  merits of the  appeals by the
court.

On April 21, 2000, the Circuit Court dismissed MAPSA's appeal based on a lack of
standing  (the  right of a party to bring a lawsuit  to court)  and  denied  its
motion for a delay of the Restructuring Order. However, MAPSA filed an appeal of
this decision.  On May 24, 2000, the Circuit Court dismissed both the Trigen and
Sweetheart Cup appeals.

On June 30, 2000,  the Maryland  Court of Appeals  granted  MAPSA's  petition to
review  whether MAPSA had standing to challenge the merits of the  Restructuring
Order and ordered a delay of the implementation of the Restructuring Order.

On July 20, 2000, the Court of Appeals  rescinded its delay of implementation of
the  Restructuring  Order,  but found that MAPSA had standing,  sending the case
back to the Circuit Court.

On July 21, 2000, the Circuit Court  re-imposed the delay of  implementation  of
the  Restructuring  Order to review the filings in the case.  The Circuit  Court
rescinded its delay on August 4, 2000;  however,  a hearing on the merits of the
Restructuring Order is scheduled for August 23, 2000.

The  effect  of the  appeals  of  the  Restructuring  Order  was  to  delay  the
implementation of customer choice in BGE's service territory.  However, once the
delay was rescinded on August 4, 2000,  BGE agreed to  retroactively  adjust its
rates as if customer choice had been  implemented July 1, 2000. While we believe
that MAPSA's case is without  merit,  no assurance can be given as to its timing
or  outcome,  which  could have a  material  adverse  effect on our,  and BGE's,
financial results.

Asset Transfer Order
- --------------------
On July 6, 2000,  MAPSA and Shell  Energy LLC filed,  in the  Circuit  Court for
Baltimore  City, a petition  for review and a delay of the Maryland  PSC's order
approving the transfer of BGE's  generation  assets issued on June 19, 2000. The
Court denied the delay on August 4, 2000. A hearing on the petition is scheduled
for August 23,  2000.  We also  believe  that this  petition  is without  merit.
However,  we cannot predict the timing,  or outcome,  of this case,  which could
have a material adverse effect on our, and BGE's, financial results.
