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 which 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 Group, Inc.  (Constellation Energy)
became the holding  company for  Baltimore  Gas and Electric  Company  (BGE) and
BGE's former subsidiary Constellation Enterprises, Inc. BGE's outstanding common
stock automatically became shares of common stock of Constellation Energy. BGE's
debt   securities,   BGE  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
Services, Inc. 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 November 10, 1999,  the  Maryland PSC issued a  Restructuring  Order that
resolves  the  major  issues  surrounding   electric   restructuring.   See  the
"Competition  and  Response  to  Regulatory  Change"  section  on  page 20 for a
detailed discussion of the Restructuring Order.

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, 1999  through  the date of this  report,  we
issued a total of 310,775 shares of common stock,  without par value,  under the
Shareholder Investment Plan. Net proceeds were about $9.5 million.

    In June 1999,  Constellation Energy arranged a $135 million revolving credit
agreement for short-term  financial  needs,  including  letters of credit.  This
facility   replaced  a  similar  facility  at  one  of  Constellation   Energy's
diversified  businesses.  As of the  date  of this  report,  letters  of  credit
totaling $23.7 million were issued under this facility.

    As of the date of this report, Constellation Energy has issued guarantees in
an amount up to $49.7 million to support the contractual  performance of certain
of its diversified subsidiaries.


BGE

Commitments
- -----------
    In 1998,  Constellation Power Source,  Inc., our power marketing and trading
business,  and Goldman, Sachs Capital Partners II L.P., an affiliate of Goldman,
Sachs & Co., formed Orion Power Holdings,  Inc. to acquire  electric  generating
plants in the United  States  and  Canada.  Constellation  Power  Source  owns a
minority  interest in Orion,  and has committed to contribute up to $175 million
in equity to fund its investment in Orion. To date,  Constellation  Power Source
has funded $104 million of this commitment.

Environmental Matters
- ---------------------
    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 must be  implemented  by  January  1,  2000.  We will  meet the
        compliance  requirements  through a combination  of switching  fuels and
        allowance trading.

    Title I addresses NOx emissions.  The Maryland Department of the Environment
(MDE) issued NOx regulations effective June 1, 1998. The MDE regulations require
major NOx  sources to reduce  NOx  emissions  up to 65% by May 1,  2000.  We are
currently  negotiating  with the MDE to settle issues  regarding the May 1, 2000
compliance  date. 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  requires  the  reduction  of NOx  emissions  up to 85% by 22  states
including  Maryland and  Pennsylvania.  This rule was appealed by several groups
including  utilities and states.  A final  decision on the appeal is expected in
early 2000.

    Based  on the  MDE and EPA  regulations,  we  currently  estimate  that  the
additional  controls  needed  at our  generating  plants  to meet  MDE's 65% NOx
emission reduction  requirements will cost  approximately $135 million.  Through
the date of this report,  we have spent  approximately $38 million to meet MDE's
65%  reduction  requirements.  We  estimate  the  additional  cost for EPA's 85%
reduction requirements to be approximately $35 million.

    In July 1997, the EPA published new National  Ambient Air Quality  Standards
for very fine  particulates and revised  standards for ozone  attainment.  These
standards may require increased  controls at our fossil generating plants in the
future.  We cannot  estimate the cost of these  increased  controls at this time
because the states,  including Maryland, still need to determine what reductions
in pollutants will be necessary to meet the federal standards.

    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 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  on the  federal
Superfund  list in January 1999, but the list 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.
We discuss this site further in BGE's 1998 Annual Report on Form 10-K.

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

    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 MDE. Based on the remedial action plans, the costs we consider to be probable
to remedy  the  contamination  are  estimated  to total $47  million  in nominal
dollars  (including  inflation).  We have recorded these costs as a liability on
our  Consolidated   Balance  Sheets  and  have



                                       13


deferred these costs, net of accumulated amortization and amounts recovered from
insurance companies, as a regulatory asset. We discuss this further in Note 4 of
BGE's 1998 Annual Report on Form 10-K.  Through the date of this report, we have
spent approximately $33 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 costs, 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 in nominal dollars ($7 million
in current dollars,  plus the impact of inflation at 3.1% over a period of up to
36 years).

    Our potential  environmental  liabilities and pending  environmental actions
are  described  further in BGE's 1998 Annual  Report on Form 10-K under "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 $21.7 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 $9.71 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   BGE  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 nine 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.

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


                                       14


Recoverability of Electric Fuel Costs
- -------------------------------------
    Historically  and until July 1, 2000,  we are allowed to recover our cost of
electric fuel if the Maryland  Public  Service  Commission  (Maryland PSC) finds
that, among other things, we have kept the productive capacity of our generating
plants at a reasonable  level.  To do this,  the Maryland PSC will  evaluate the
performance  of our  generating  plants,  and  will  determine  if we  used  all
reasonable and cost-effective maintenance and operating control procedures.

    The Maryland PSC, under the Generating Unit  Performance  Program,  measures
annually  whether we have  maintained the productive  capacity of our generating
plants  at  reasonable  levels.  To do  this,  the  program  uses a  system-wide
generating performance target and an individual performance target for each base
load  generating  unit. In fuel rate  hearings,  actual  generating  performance
adjusted for planned outages will be compared first to the system-wide target.

    If that target is met, it should mean that the  requirements of Maryland law
have been met. If the system-wide target is not met, each unit's adjusted actual
generating  performance will be compared to its individual performance target to
determine  if the  requirements  of  Maryland  law have been met and, if not, to
determine  the basis for  possibly  imposing a penalty  on BGE.  Even if we meet
these targets,  parties to fuel rate hearings may still question whether we used
all reasonable and cost-effective procedures to try to prevent an outage. If the
Maryland  PSC decides we were  deficient  in some way,  the Maryland PSC may not
allow us to recover the cost of replacement energy.

    The two units at Calvert  Cliffs use the  cheapest  fuel.  As a result,  the
costs of  replacement  energy  associated  with  outages  at these  units can be
significant.  We cannot  estimate  the amount of  replacement  energy costs that
could be  challenged or  disallowed  in future fuel rate  proceedings,  but such
amounts could be material.  We discuss significant  disallowances in prior years
related to past  outages at Calvert  Cliffs in BGE's 1998 Annual  Report on Form
10-K.

    Under the terms of the Restructuring  Order, BGE's electric fuel rate clause
will be discontinued  effective July 1, 2000. After that date,  earnings will be
affected by changes in the cost of fuel and energy.  We discuss  competition and
its impact on BGE's generation business further in the "Competition and Response
to Regulatory  Change" section of  Management's  Discussion and Analysis on page
20. The  discontinuance  of BGE's electric fuel rate clause is discussed further
in the "Regulation by the Maryland PSC" section in  Management's  Discussion and
Analysis on page 18.

California Power Purchase Agreements
- ------------------------------------
    Constellation Power, Inc. and subsidiaries and Constellation Investments,
Inc.  (whose  power  projects  are managed by  Constellation  Power) have $308.2
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  "transition  period"  to  describe  the time frame when the
10-year  periods for fixed  energy  rates  expire for these 14 power  generation
projects and they begin supplying  electricity at variable rates. The transition
period  for  some of the  projects  began  in 1996  and  will  continue  for the
remaining projects through 2000.

    The projects that have already transitioned to variable rates have had lower
revenues  under  variable  rates  than  they did  under  fixed  rates.  When the
remaining  projects  transition 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  "Diversified  Businesses"
section beginning on page 26.

    We  discuss  our other  diversified  businesses'  activities  further in the

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.

    BGE is an electric and gas public utility  company with a service  territory
in the City of Baltimore and in all or part of ten counties in Central Maryland.
Constellation   Enterprises  is  a  holding  company  for  several   diversified
businesses engaged primarily in energy services.

    Our energy services businesses are:

    o   Constellation  Power  Source,(TM)  Inc. -- our wholesale power marketing
        and trading business,
    o   Constellation  Power,  Inc.,(TM) and  Subsidiaries -- our power projects
        business,
    o   Constellation  Energy  Source,(TM)  Inc.  --  our  energy  products  and
        services business,
    o   Constellation  Nuclear  Services,  (TM) Inc. -- our  nuclear  consulting
        services business,
    o   BGE Home  Products &  Services,(TM)  Inc. and  Subsidiaries  -- our home
        products,   commercial  building  systems,  and  residential  and  small
        commercial gas retail marketing business, and
    o   District Chilled Water General Partnership (ComfortLink(R)) -- a general
        partnership in which BGE is a partner that provides cooling services for
        commercial customers in Baltimore.

    Constellation Enterprises, Inc. also has two other subsidiaries:

    o   Constellation   Investments,(TM)   Inc.  --  our  financial  investments
        business, and
    o   Constellation  Real  Estate  Group,(TM)  Inc.  -- our  real  estate  and
        senior-living facilities business.

    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
Services, Inc. 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.

    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 and Strategy
- -------------------------
    The electric utility industry is undergoing rapid and substantial change. On
April 8, 1999,  Maryland  enacted  legislation  authorizing  customer choice and
competition among electric suppliers.  In addition,  on June 29, 1999, BGE and a
majority of the active parties involved in the electric restructuring proceeding
filed  a  proposed  settlement   agreement  with  the  Maryland  Public  Service
Commission  (Maryland PSC) that addresses the major issues surrounding  electric
restructuring.  On November  10, 1999,  the Maryland PSC issued a  Restructuring
Order that approved the proposed settlement agreement.

    All electric  customers,  except a few commercial  and industrial  companies
that have signed contracts with BGE, will be able to choose suppliers on July 1,
2000.  Also, upon receipt of all regulatory  approvals,  on July 1, 2000, all of
BGE's  generation   assets  will  be  moved  to  nonregulated   subsidiaries  of
Constellation Energy. These assets represent about 6,240 megawatts of generation
capacity.  These matters are discussed  further in the "Competition and Response
to Regulatory Change" section on page 20.

    In  Maryland,  all gas  customers  were able to choose  suppliers  beginning
November 1, 1999.

    This change toward  customer choice will  significantly  impact our business
going forward.  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. We will continue to invest in the growth of our
nonregulated  businesses,  especially our power projects and power marketing and
trading  businesses,  with the objective of providing new sources of earnings in
anticipation of lower electric utility revenues.  In addition, we might consider
one or more of the following strategies:


                                       16


    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,
    o   spin-off or sale of one or more businesses, and
    o   growth of earnings from other nonregulated businesses.

    We cannot predict whether any of the strategies described above may actually
occur, or what their effect on our financial  condition 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 results
of operations and financial condition in the future.  These factors include, but
are not limited to, the loss of  customers,  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
38.  Additional detail on competition is included in BGE's 1998 Annual Report on
Form 10-K under the heading "Electric Regulatory Matters and Competition."

    In this discussion and analysis,  we explain the general financial condition
and the results of operations for Constellation Energy 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 our  expenditures  for capital  projects were in the current period
        and what we expect them 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 nine months ended  September  30, 1999 and 1998. 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.

     Also,  this  discussion  and  analysis  is  based on the  operation  of the
electric   generation  portion  of  our  utility  business  under  current  rate
regulation.  Our electric business will change  significantly  beginning July 1,
2000 as we enter into the transition to full retail customer choice for electric
generation.  Accordingly,  the results of  operations  and  financial  condition
described in this  discussion  and analysis are not  necessarily  indicative  of
future performance.

Results of Operations  for the Quarter and Nine Months Ended  September 30, 1999
Compared With the Same Periods of 1998
- -------------------------------------------------------------------------------

    In this section,  we discuss our earnings and the factors affecting them. We
begin with a general overview,  then separately discuss earnings for our utility
business and for our diversified businesses.

Quarter Ended September 30, 1999
- --------------------------------
    Our total earnings for the quarter ended  September 30, 1999 decreased $24.8
million, or $.17 per share, compared to the same period of 1998.

    In the third quarter of 1999, we had lower utility earnings  compared to the
same  period of 1998  mostly  because we  deferred  $37.5  million  of  electric
revenues to reflect certain terms of the proposed settlement  agreement with the
Maryland  PSC, and we incurred  costs  associated  with  Hurricane  Floyd.  This
decrease  in  utility  earnings  compared  to 1998 was  partially  offset by the
settlement of a capacity  contract with PECO Energy  Company (PECO) in the third
quarter of 1998. We discuss our utility  earnings in more detail in the "Utility
Business" section on page 18.


                                       17


    In the  third  quarter  of 1999,  diversified  business  earnings  decreased
compared to the same period of 1998 mostly  because of lower  earnings  from our
power projects and financial investments businesses.  This decline was partially
offset by higher  earnings  from our power  marketing and trading  business.  We
discuss  our  diversified   business   earnings   further  in  the  "Diversified
Businesses" section beginning on page 26.

Nine Months Ended September 30, 1999
- ------------------------------------
    Our total  earnings for the nine months ended  September 30, 1999  decreased
$5.8 million, or $.05 per share, compared to the same period of 1998.

    In the nine months ended September 30, 1999, we had higher utility  earnings
compared to the same period of 1998 mostly because we sold more  electricity and
gas this year and we settled a capacity contract with PECO in 1998. The increase
in utility  earnings was  partially  offset by the deferral of $37.5  million of
electric  revenues as discussed  above,  and higher  operations and  maintenance
expenses  mostly due to Hurricane Floyd and a major winter ice storm. We discuss
our utility earnings in more detail in the "Utility Business" section below.

    In the nine months ended September 30, 1999,  diversified  business earnings
decreased  compared to the same period of 1998 mostly  because of lower earnings
from our power projects and financial investments  businesses.  This decline was
partially  offset  by  higher  earnings  from our power  marketing  and  trading
business.   We  discuss  our  diversified   business  earnings  further  in  the
"Diversified Businesses" section beginning on page 26.

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


Regulation by the Maryland PSC
- ------------------------------
    The Maryland PSC determines the rates we can charge our customers. Our rates
consist  of a "base  rate"  and a "fuel  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 the highest. Gas base rates are not affected by seasonal changes.

    From time to time,  when  necessary  to cover  increased  costs,  we ask the
Maryland PSC for base rate increases.  Similarly, other parties may petition the
Maryland  PSC to lower  BGE's base rates.  The  Maryland  PSC holds  hearings to
determine what changes,  if any, should be made to base rates.  The Maryland PSC
has historically  allowed us 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.  Under the Restructuring  Order,  BGE's electric base rates are frozen at
the  current  levels  until July 1, 2000.  At that  time,  electric  residential
customer  choice  begins and  residential  base rates will decrease by about $54
million per year. Those reduced rates will be frozen until June 30, 2006.

    The  Maryland  PSC allows us to include in base 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. Under the Restructuring Order, the electric conservation
surcharge and associated profit  limitation will be discontinued  effective July
1, 2000.

    In addition, we charge our electric customers separately for the fuel we use
to generate  electricity  (nuclear fuel, coal, gas, or oil) and for the net cost
of purchases  and sales of  electricity  (primarily  with other  utilities).  We
charge the actual cost of these items to the  customer  with no profit to us. If
these fuel costs go up, the  Maryland  PSC permits us to increase the fuel rate.
If these costs go down, our customers benefit from a reduction in the fuel rate.
The fuel rate is impacted  most by the amount of  electricity  generated  at our
Calvert Cliffs Nuclear Power Plant (Calvert  Cliffs) because the cost of nuclear
fuel is cheaper than coal, gas, or oil.


                                       18


    We discuss this in more detail in Note 1 of BGE's 1998 Annual Report on Form
10-K.

    Changes in the fuel rate normally do not affect  earnings.  However,  if the
Maryland PSC disallows  recovery of any part of the fuel costs, our earnings are
reduced.  We discuss this in the "Recoverability of Electric Fuel Costs" section
of the Notes to Consolidated Financial Statements on page 15.

    Under the  Restructuring  Order,  BGE's  electric  fuel rate  clause will be
discontinued  effective July 1, 2000. After that date, earnings will be affected
by the  changes in the cost of fuel and energy.  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  will be  refunded to or
collected from our customers over a period to be determined by the Maryland PSC.
At September 30, 1999,  BGE's actual costs of fuel and energy were $66.1 million
higher than the electric fuel rate revenues collected from customers.

    We also  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 24.

    Please refer to the "Competition and Response to Regulatory  Change" section
on page 20 for a detailed discussion of the Restructuring Order.


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.

    Effective  March 1, 1998, the Maryland PSC allowed us to implement 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 24.

    We show the number of heating and cooling  degree days in the  quarters  and
nine months ended  September 30, 1999 and 1998 and the percentage  change in the
number of degree days between these periods in the following table:

                       Quarter Ended    Nine Months Ended
                        September 30      September 30
                      ---------------  ------------------
                        1999    1998     1999      1998
                      -------- ------  --------  --------

Heating degree days...   75      74    2,981     2,559
  Percent change
  compared to prior period  1.4%             16.5%

Cooling degree days...  629     625      832       904
  Percent change
  compared to prior period  0.6%            (8.0)%

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.

    Usage per customer refers to all other items  impacting  customer sales that
cannot be separately measured. 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.


                                       19




Competition and Response to Regulatory Change
- ---------------------------------------------
    Our  electric  and gas  businesses  are  also  affected  by  competition  as
discussed below.

Electric Business
- -----------------
    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  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.  Major  elements of the Act and the  accompanying  tax
legislation  are  discussed in detail in our June 30, 1999  Quarterly  Report on
Form 10-Q.

    On June 29, 1999, BGE and a majority of the active  parties  involved in the
electric restructuring proceeding filed a proposed settlement agreement with the
Maryland  PSC. On November  10, 1999,  the  Maryland PSC issued a  Restructuring
Order that approved the proposed settlement  agreement.  The Restructuring Order
resolves the electric restructuring proceeding (transition costs, customer price
protections,  and unbundled rates for electric  services) and the petition filed
in September 1998 by the Office of People's  Counsel (OPC) to lower our electric
base rates. In addition,  the Restructuring  Order accelerates the timetable for
customer  choice and addresses  certain other  provisions of the Act. There is a
30-day period to file an appeal to the  Restructuring  Order.  We cannot predict
whether an appeal will be filed. The electric  restructuring  proceeding and the
petition  filed by the OPC are  discussed  in BGE's 1998  Annual  Report on Form
10-K. The major provisions of the Restructuring Order are:

    o   All customers,  except a few  commercial  and industrial  companies that
        have signed  contracts  with BGE, will be able to 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 will reduce 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 will 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   Electric  delivery  service rates will be frozen for a four-year  period
        for commercial and industrial customers. The generation and transmission
        components of rates will be frozen for different time periods  depending
        on the service options selected by those customers.
    o   BGE will be allowed to recover $528 million 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
        will be included in delivery  service rates  effective  July 1, 2000 and
        will be recovered on a basis approximating  their existing  amortization
        schedules.
    o   Starting  July 1,  2000,  BGE  will  unbundle  rates  to  show  separate
        components  for delivery  service,  transition  charges,  standard offer
        services (generation), transmission, universal service, and taxes.
    o   On  July  1,  2000,   BGE  will  transfer,   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 will  reduce  its  generation  assets,  as  described  later in this
        section, 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  is  provided  for  low-income   customers   without
        increasing  their bills.  BGE will provide its share of a statewide fund
        totaling $34 million.

    We believe that the Restructuring  Order provides  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 our business.  Accordingly, in the fourth quarter
of 1999, we will adopt the provisions of SFAS No. 101,  Regulated




                                       20


Enterprises - Accounting  for the  Discontinuation  of FASB Statement No. 71 and
Emerging  Issues  Task Force  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 the following discussion.

    SFAS No. 101 requires the elimination of the effects of rate regulation that
have been recognized as regulatory  assets and liabilities  pursuant to SFAS No.
71. Under the  Restructuring  Order,  BGE's  generation-related  net  regulatory
assets will be effectively  recovered  through BGE's regulated  transmission and
distribution  business.  We expect  that there will be no net impact on BGE's or
Constellation   Energy's   earnings   associated   with  the   recovery  of  the
generation-related net regulatory assets.

    Pursuant to SFAS No. 101, the book value of property,  plant,  and equipment
may not be adjusted  unless those assets are impaired  under the  provisions  of
SFAS No.  121,  Accounting  for the  Impairment  of  Long-Lived  Assets  and for
Long-Lived  Assets To Be Disposed Of. The process of  evaluating  and  measuring
impairment  under the provisions of SFAS No. 121 involves two steps.  First,  we
must  compare  the net book  value  of each  generating  plant to the  estimated
undiscounted  future  net  operating  cash flows from that  plant.  An  electric
generating  plant is  considered  impaired  when  its  undiscounted  future  net
operating  cash flows are less than its net book value.  Second,  we compute the
fair value of each plant that is determined to be impaired  based on the present
value of that plant's estimated future net operating cash flows discounted using
an  interest  rate that  considers  the risk of  operating  that  facility  in a
competitive environment.  To the extent that the net book value of each impaired
electric generation plant exceeds its fair value, we must record a write-down.

    Under  the  Restructuring  Order,  BGE  will  recover  $528  million  of its
potentially  stranded  investments and utility  restructuring  costs through the
competitive  transition charge component of its customer rates beginning July 1,
2000. This recovery  mostly relates to the stranded costs  associated with BGE's
Calvert Cliffs  Nuclear Power Plant,  whose book value is  substantially  higher
than its  estimated  fair  value.  However,  Calvert  Cliffs  is not  considered
impaired  under  the  provisions  of SFAS No.  121 since  its  estimated  future
undiscounted cash flows exceed its book value. Accordingly,  BGE will not record
any impairment write-down related to Calvert Cliffs. We will, however, recognize
impairment  losses  associated  with  certain  of our  fossil  plants  under the
provisions of SFAS No. 121.

    BGE has contracts to purchase electric capacity and energy that are expected
to be uneconomic upon the  deregulation of electric  generation.  Therefore,  we
must record a charge  based on the net present  value of the excess of estimated
contract  costs over the  market-based  revenues to recover these costs over the
remaining terms of the contracts.  In addition,  BGE has deferred certain energy
conservation  expenditures  that will not be recovered  through its transmission
and distribution  business under the Restructuring Order.  Accordingly,  we must
record a charge to eliminate the regulatory  asset  previously  established  for
these deferred expenditures.

    At the date of this  report,  we  estimate  that the total  charge for BGE's
electric  generating  plants that are impaired,  losses on uneconomic  purchased
capacity and energy contracts, and deferred energy conservation  expenditures is
approximately $150 million to $175 million  (after-tax).  The actual charge will
be recorded in the fourth quarter of 1999.

    BGE will  record  approximately  $95  million of this  charge on its balance
sheet. This will consist of establishing a $150 million  regulatory asset of its
regulated  transmission and  distribution  business,  net of  approximately  $55
million of  associated  deferred  income  taxes.  The  regulatory  asset will be
amortized as it is recovered from  ratepayers  through June 30, 2000.  This will
accomplish the $150 million  reduction of its generation  plants required by the
Restructuring Order.

    We will record an after-tax,  extraordinary  charge against earnings for the
approximately  $55 million to $80 million  remaining portion of the $150 million
to  $175  million   described  above  that  will  not  be  recovered  under  the
Restructuring Order.

    As a condition of the Maryland PSC's  consolidation of the September 3, 1998
Office of  People's  Counsel  petition to lower  electric  base rates with BGE's
electric restructuring  transition proposal, we agreed to make our rates subject
to refund  effective  July 1, 1999.  Therefore,  BGE deferred  $37.5  million of
revenues  it  collected  during the third  quarter  pending the  Maryland  PSC's
approval  of  the  proposed  settlement.  However,  with  the  issuance  of  the
Restructuring  Order,  these  deferred  revenues  will be reversed in the fourth
quarter,  as our current  rates will be frozen  through  June 30,  2000.  In the
fourth  quarter,  BGE will also  record $75 million in  amortization  expense or
one-half of the $150 million  reduction of generation plants provided for in the
Restructuring Order as discussed above.


                                       21


Gas Business
- ------------
    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 industrial and commercial gas customers, and effective
November 1, 1999, all BGE residential customers, have the option to purchase gas
from other suppliers.

    Our utility earnings for the quarter ended September 30, 1999 decreased $2.0
million,  or $.01 per share  compared  to the same  period of 1998.  Our utility
earnings for the nine months ended September 30, 1999,  increased $10.3 million,
or $.06 per share  compared to the same  period of 1998.  We discuss the factors
affecting utility earnings below.

    The  discussion  below  reflects the  operations of the electric  generation
portion of our utility  business  under current rate  regulation by the Maryland
PSC. Our electric business will change  significantly  beginning July 1, 2000 as
we enter  into the  transition  to full  retail  customer  choice  for  electric
generation. Also, upon receipt of all regulatory approvals, on July 1, 2000, all
of  BGE's  generation  assets  will be  moved to  nonregulated  subsidiaries  of
Constellation Energy. These assets represent about 6,240 megawatts of generation
capacity.  We have  not  determined  the  impact  of  transferring  all of BGE's
generation assets to nonregulated subsidiaries on BGE's assets, revenues and net
income.  However, such amounts could be material. We discuss this further in the
"Deregulation and Strategy" section on page 16.

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 1999 compared to 1998 were:

Commercial...........       0.2               1.4
Industrial...........     (11.9)             (7.3)

    During the quarter ended  September 30, 1999,  we sold more  electricity  to
residential  customers due to higher usage per customer and warmer  weather.  We
sold about the same amount of  electricity  to  commercial  customers  as we did
during the same period of 1998. We sold less electricity to industrial customers
mostly  because  usage by  Bethlehem  Steel  (our  largest  customer)  and other
industrial customers  decreased.  Usage decreased at Bethlehem Steel as a result
of a shut down from June to August  for a planned  upgrade  to their  facilities
that temporarily reduced their electricity consumption.


                                       22


    During the nine months ended September 30, 1999, we sold more electricity to
residential  customers due to higher usage per customer,  colder winter weather,
and an  increased  number of  customers.  The  increase in sales to  residential
customers was partially  offset by milder  spring and early summer  weather.  We
sold more  electricity  to  commercial  customers  mostly  due to colder  winter
weather  and an  increased  number of  customers.  We sold less  electricity  to
industrial   customers  mostly  because  usage  by  Bethlehem  Steel  and  other
industrial customers decreased.

Base Rates
- ----------
    During the quarter and nine  months  ended  September  30,  1999,  base rate
revenues  increased  compared to the same periods of 1998 mostly  because we had
higher conservation surcharge revenues.

Fuel Rates
- ----------
    During the quarter and nine  months  ended  September  30,  1999,  fuel rate
revenues were about the same compared to the same periods of 1998.


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 a
regional   power  pool  with  members  that   include  many   wholesale   market
participants,  as well as BGE and six 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 nine months ended  September  30, 1999,  we had lower
interchange  and other sales compared to the same periods of 1998 mostly because
the  increased  demand  for  system  sales  reduced  the amount of energy we had
available for off-system sales.


Other
- -----
    During the quarter and nine months ended September 30, 1999,  other revenues
decreased compared to the same periods of 1998 mostly because BGE deferred $37.5
million of electric  revenues that it collected during the third quarter of 1999
on the basis that as of  September  30,  1999 this  amount was subject to refund
pending the Maryland PSC's  approval of the proposed  settlement  agreement.  We
discuss  the  revenue  deferral  further in the  "Competition  and  Response  to
Regulatory Change" section on page 20.

Actual Costs
- ------------
    During the quarter and nine months  ended  September  30,  1999,  our actual
costs of fuel to generate  electricity  (nuclear  fuel,  coal,  gas, or oil) and
electricity  we bought  from others was higher  compared to the same  periods of
1998 mostly  because the price of  electricity we bought from others was higher.
The price of electricity  changes based on market  conditions,  complex  pricing
formulas for PJM transactions,  and contract terms. The increase in actual costs
was partially offset by our settlement of a capacity contract with PECO in 1998.

Electric Fuel Rate Clause
- -------------------------
    Under  the  electric  fuel rate  clause,  we defer  (include  as an asset or
liability on the  Consolidated  Balance Sheets and exclude from the Consolidated
Statements of Income) the difference between our actual costs of fuel and energy
and what we collect from  customers  under the fuel rate in a given  period.  We
either bill or refund our customers that difference in the future.

    During the quarter and nine months  ended  September  30,  1999,  our actual
costs of fuel and energy were higher  than the fuel rate  revenues we  collected
from our customers.

Gas System Sales Volumes
- ------------------------
    The percentage changes in our gas system sales volumes, by type of customer,
in 1999 compared to 1998 were:

                        Quarter Ended   Nine Months Ended
                        September 30      September 30

   Commercial.........      8.5              12.7
   Industrial.........    (10.6)             (6.3)

    During the quarter  ended  September 30, 1999, we sold about the same amount
of gas to  residential  customers  as we did during the same period of 1998.  We
sold more gas to  commercial  customers  due to higher usage per customer and an
increased number of customers.  We sold less gas to industrial  customers mostly
because usage by Bethlehem Steel and other industrial customers decreased. Usage
by  Bethlehem  Steel  decreased  due to a shut down  from  June to August  for a
planned upgrade to their facilities.

    During  the nine  months  ended  September  30,  1999,  we sold  more gas to
residential  customers mostly because of two factors:  colder winter weather and
the number of customers increased.  This was partially offset by lower usage per
customer.  We sold more gas to  commercial  customers  mostly  because of colder
winter  weather,  increased  usage  per  customer,  and an  increased  number of
customers.  We sold less gas to  industrial  customers  mostly  because usage by
Bethlehem Steel and other industrial customers decreased.

Base Rates
- ----------
    During the quarter ended  September 30, 1999,  base rate revenues were about
the same compared to the same period of 1998.

    During the nine months ended  September  30, 1999,  base rate  revenues were
higher than they were during the same period of 1998.  Effective  March 1, 1998,
the Maryland PSC allowed us to increase our base rates which  increased our base
rate revenues over the  twelve-month  period March 1998 through February 1999 by
approximately $16 million.

Weather Normalization
- ---------------------
    Effective  March 1, 1998, the Maryland PSC allowed us to implement 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
will be  based  on  weather  that is  considered  "normal"  for the  month  and,
therefore, will not be 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 which include a market based
rate incentive  mechanism.  These clauses  operate  similar to the electric fuel
rate clause  described in the  "Electric  Fuel Rate Clause"  section on page 23.
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  September 30, 1999, gas cost  adjustment  revenues
increased  compared to the same  period of 1998 mostly  because we sold gas at a
higher price.


                                       24


    During  the nine  months  ended  September  30,  1999,  gas cost  adjustment
revenues  increased  compared to the same period of 1998 mostly  because we sold
more gas at a higher price.

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).

    During the quarter and nine months ended  September 30, 1999,  revenues from
off-system  gas sales  decreased  compared  to the same  periods of 1998  mostly
because we sold less gas off-system.

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 nine  months  ended
September 30, 1999,  actual gas costs decreased  compared to the same periods of
1998 mostly because we bought less gas for off-system sales.

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 nine months ended  September 30, 1999, our actual gas
costs were lower than the fuel rate revenues we collected from our customers.


Other Operating Expenses
- ------------------------

Operations and Maintenance Expenses
- -----------------------------------
    During the quarter ended  September  30, 1999,  operations  and  maintenance
expenses  were  about the same  compared  to the same  period of 1998.  In 1999,
operations and maintenance expenses include  approximately $7.5 million of costs
associated  with  Hurricane  Floyd.  This was  offset by higher  operations  and
maintenance  expenses in the third  quarter of 1998  associated  with the annual
refueling outage at Calvert Cliffs.

    During the nine months ended September 30, 1999,  operations and maintenance
expenses  increased  $14.8  million  compared  to the same period of 1998 mostly
because of costs related to Hurricane  Floyd and a major winter ice storm during
1999.  This  increase  was  partially  offset by the $6.5  million  write-off of
contributions to a third party for a low-level radiation waste facility that was
never completed, which we recorded in 1998.


Depreciation and Amortization Expenses
- --------------------------------------
    During the quarter and nine months ended  September  30, 1999,  depreciation
and  amortization  expenses  were about the same compared to the same periods of
1998.

Taxes Other Than Income Taxes
- -----------------------------
    During the quarter ended  September 30, 1999,  taxes other than income taxes
increased  $3.1  million  compared to the same period of 1998 mostly  because of
higher property taxes.

    During the nine months ended  September  30,  1999,  taxes other than income
taxes increased $8.6 million  compared to the same period of 1998 mostly because
of two factors:  higher property taxes and higher payroll taxes  associated with
increased labor costs.


Interest Expense
- ----------------
    During the  quarter and nine  months  ended  September  30,  1999,  interest
expense was about the same compared to the same periods of 1998.



                                       25


Income Taxes
- ------------
    During  the  quarter  ended  September  30,  1999,  our total  income  taxes
decreased  $16.1 million  compared to the same period of 1998 mostly  because we
had lower taxable income from our diversified businesses.

    During the nine months  ended  September  30,  1999,  our total income taxes
decreased $7.3 million compared to the same period of 1998 mostly because we had
lower taxable income from our diversified  businesses partially offset by higher
taxable income from our utility operations.

Diversified Businesses
- ----------------------
    Our diversified businesses engage primarily in energy services. We list each
of our  diversified  businesses  in the  "Introduction"  section  on page 16. We
describe our  diversified  businesses in more detail in BGE's 1998 Annual Report
on Form 10-K under "Item 1. Business -- Diversified Businesses."

    Constellation  Enterprises  and its  subsidiaries  were  subsidiaries of BGE
prior  to  April  30,  1999  and  are  included  in the  consolidated  financial
statements of BGE through that date.

1998.  Our  total  diversified  business  earnings  for the  nine  months  ended
September 30, 1999 decreased $16.1 million,  or $.11 per share,  compared to the
same period of 1998.

    We discuss the factors affecting the earnings of our diversified  businesses
below.

Energy Services
- ---------------
Power Marketing and Trading
- ---------------------------
    During the quarter and nine months ended  September 30, 1999,  earnings from
our power marketing and trading business  increased compared to the same periods
of 1998 mostly because of increased transaction margins and volume.

    Constellation Power Source uses the mark-to-market  method of accounting for
its trading activities.  We discuss the mark-to-market  method of accounting and
Constellation  Power  Source's  trading  activities in more detail in BGE's 1998
Annual Report on Form 10-K.

    As a result of the nature of its  trading  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.

    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 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 September 30, 1999 compared to December 31, 1998 because of greater
business activity during the period.


                                       26


Power Projects
- --------------
    During the quarter and nine months ended  September 30, 1999,  earnings from
our power  projects  business  decreased  compared  to the same  periods of 1998
mostly because of two factors:

    o   In August  1999,  our power  projects  business  recorded a $6.7 million
        after-tax,  or $.05 per share  write-off of a geothermal  power project.
        The write-off  occurred  because the expected  future cash flow from the
        project  is less  than the  investment  in the  project  as a result  of
        declining water temperature of the geothermal resource used by the plant
        for production.
    o   In July 1998,  our power  projects  business  recorded  a $10.4  million
        after-tax,  or $.07 per  share,  gain for its  share  of  earnings  in a
        partnership.  The  partnership  recognized a gain on the sale of a power
        purchase agreement.

California Power Purchase Agreements
- ------------------------------------
    Constellation  Power and  subsidiaries  and  Constellation  Investments have
$308.2 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 $12.4  million,  or $.08 per share,  for the
quarter ended  September 30, 1999 compared to $24.0  million,  or $.16 per share
for the same period of 1998. Earnings from these projects were $26.3 million, or
$.18 per share,  for the nine months ended  September 30, 1999 compared to $41.0
million, or $.28 per share for the same period of 1998.

    Under these  agreements,  the  electricity  rates change from fixed rates to
variable rates  beginning in 1996 and continue  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.

    Our power projects business is pursuing alternatives for some of these power
generation 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.

    At the  date of this  report,  ten  projects  had  already  transitioned  to
variable rates.  The remaining four projects that have the highest revenues will
transition  between February and December 2000. The projects which  transitioned
in 1999  contributed  $2.1  million,  or $.01  per  share to the  quarter  ended
September  30, 1999  earnings and $5.4  million,  or $.04 per share for the nine
months  ended  September  30,  1999  earnings.   Those  changing  over  in  2000
contributed  $9.9 million,  or $.07 per share to the quarter ended September 30,
1999  earnings  and $20.4  million,  or $.14 per share for the nine months ended
September  30,  1999  earnings.  We expect  earnings  ultimately  to decrease by
similar amounts as these projects transition.

    We also describe these  projects and the transition  process in the Notes to
Consolidated Financial Statements on page 15.


International
- -------------
    At September 30, 1999, Constellation Power had invested about $182.0 million
in 10 power  projects in Latin America  compared to $104.4  million  invested in
Latin America at September 30, 1998. These investments include:

    o   the  purchase of a 51% interest in a  Panamanian  electric  distribution
        company for  approximately $90 million in 1998 by an investment group in
        which subsidiaries of Constellation Power hold an 80% interest, and
    o   approximately   $98  million  for  the  purchase  of  existing  electric
        generation  facilities and the  construction  of an electric  generation
        facility in Guatemala.

    In the  future,  Constellation  Power  expects to expand its power  projects
business further in both domestic and international projects.


Other Energy Services
- ---------------------
    During the quarter and nine months ended  September 30, 1999,  earnings from
our other energy services  businesses  decreased compared to the same periods of
1998 mostly  because of lower gross  margins  from energy  trading at our energy
products and services business.


                                       27


Other Diversified Businesses
- ----------------------------
    During the quarter and nine months ended  September 30, 1999,  earnings from
our other diversified businesses were lower compared to the same periods of 1998
mostly  because our financial  investments  business had lower earnings from its
investment in Capital Re Corporation (Capital Re).

    In May 1999,  our  financial  investments  business  announced  that it will
exchange  its  shares of common  stock in  Capital  Re for  common  stock of ACE
Limited (ACE) as part of a business combination whereby ACE would acquire all of
the  outstanding  capital  stock of  Capital  Re. 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 of this
pending business combination.

    In  September  1999,  our  financial  investments  business  wrote-down  its
investment in Capital Re stock by an additional $17.3 million after-tax, or $.12
per share to reflect the market  value of $12.50 per share for this  investment.
The  initial  close was  scheduled  for  early in the  fourth  quarter  of 1999.
However, in October 1999, another insurance company, XL Capital, Inc., submitted
a  competing  bid  to  acquire  the  shares  of  common  stock  in  Capital  Re.
Subsequently,  ACE matched the competing bid with an offer  composed of cash and
stock,  whose exchange rate was increased  from their initial  offer.  As of the
date of this  report,  the market  value of the current  offer is  approximately
$14.40 per share and is  partially  dependent  on the market value of ACE stock.
Upon  closing,  which is expected to occur in the first  quarter of 2000,  final
valuation  will occur,  and our financial  investments  business will record any
change in the market value of this investment to the income statement.

    Earnings  from our real estate and  senior-living  facilities  business were
about the same compared to the same periods of 1998. In September 1999, earnings
include a $3.4  million  after-tax,  or $.02 per  share  write-down  of  certain
senior-living  facilities  related to the sale of these  facilities as discussed
below.  This  write-down  was offset by higher  earnings from various other real
estate projects in 1999.

    In August 1999,  our  senior-living  facilities  business  announced that it
entered into an agreement to sell all but one of its senior-living facilities to
Sunrise Assisted Living,  Inc. Under the terms of the agreement,  Sunrise was to
acquire twelve of our existing senior-living facilities,  three facilities under
construction,  and several sites under development for $72.2 million in cash and
$16.0  million in debt  assumption.  We have been unable to reach  agreement  on
financing  issues that  subsequently  arose, and the agreement was terminated in
November  1999.  As a  result,  our real  estate  and  senior-living  facilities
business will now engage a third-party  management company to assist in managing
its senior-living  facilities portfolio including the three facilities now under
construction,  which will be  completed  by our real  estate  and  senior-living
facilities business in the first half of 2000.

    In April 1999,  Constellation  Real Estate  Group,  Inc.  (CREG) sold Church
Street  Station,  our  entertainment,  dining,  and retail  complex in  Orlando,
Florida for $11.5 million, the approximate book value of the complex.

    Most   of   CREG's    remaining   real   estate    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  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 diversified subsidiaries.

    Our current real estate  strategy is to hold each real estate  project until
we can realize a  reasonable  value for it. We evaluate  strategies  for all our
businesses,  including  real estate,  on an ongoing  basis.  We anticipate  that
competing  demands  for our  financial  resources  and  changes  in the  utility
industry  will  cause  us  to  evaluate  thoroughly  all  diversified   business
strategies on a regular basis so we use capital and other  resources in a manner
that is most beneficial.


                                       28


    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 projects. If we were to decide to sell our real estate projects, we could
have  write-downs.  In addition,  if we were to sell our real estate 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.

    Under  accounting  rules,  we are required to write down the value of a real
estate 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.

Cash Flows

For the nine months ended September 30:
- ---------------------------------------
                                    1999        1998
                                    ----        ----
                                      (In millions)
  Cash provided by (used in):
  Operating Activities            $ 483.5       $ 654.8
  Investing Activities             (441.8)       (415.1)
  Financing Activities             (159.0)       (187.2)

    During the nine months ended September 30, 1999, we generated less cash from
operations  compared  to the same  period in 1998  mostly  because of changes in
working capital requirements.

    During the nine  months  ended  September  30,  1999,  we used more cash for
investing  activities  compared to the same period in 1998 mostly because of the
following  factors:  our power  marketing  and trading  business  increased  its
investment in Orion Power  Holdings,  Inc. by $97.7 million,  our power projects
business  increased its investment in power  projects by $25.7 million,  and BGE
increased  its  capital  expenditures  by $11.9  million.  These  increases  are
partially  offset by a $60.7  million  investment  for the  purchase  of a power
generation  facility in Guatemala  in 1998 by our power  projects  business.  In
addition, our real estate and senior-living facilities business invested less in
1999 compared to the same period of 1998.

    During the nine  months  ended  September  30,  1999,  we used less cash for
financing  activities  compared  to the same  period of 1998  mostly  because we
redeemed  less BGE  preference  stock  and our net  short-term  borrowings  were
higher.  This was partially offset by an increase in the repayments of long-term
debt and a decrease in the issuances of long-term debt.


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 actual  consolidated
capital  requirements  for the nine months ended September 30, 1999,  along with
estimated  annual amounts for the years 1999 through 2001, are shown on page 30.
For the twelve months ended  September 30, 1999,  the ratio of earnings to fixed
charges  for  Constellation  Energy  was 2.68.  The ratio of  earnings  to fixed
charges for BGE was 3.32 and the ratio of earnings to combined fixed charges and
preferred and preference dividend requirements for BGE was 3.00.


                                       29


    Investment  requirements for 1999 through 2001 include  estimates of funding
for existing and anticipated  projects.  We continuously review and modify those
estimates.  Actual investment  requirements may vary from the estimates included
in the table below because of a number of factors including:

    o   regulation, legislation, and competition,
    o   load growth,
    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 "Forward
Looking Statements" on page 38.

    Upon  receipt of all  regulatory  approvals,  on July 1, 2000,  all of BGE's
generation  assets will be moved to nonregulated  subsidiaries of  Constellation
Energy.  The discussion and table for capital  requirements  below include these
generation assets as part of the utility business.

Capital Requirements of Our Utility Business
- --------------------------------------------
    Our estimates of future  electric  construction  expenditures do not include
costs to build more generating units. Electric construction expenditures include
improvements  to  generating  plants and to our  transmission  and  distribution
facilities.

    Future  electric  construction  expenditures  include  estimated  costs  for
replacing the steam  generators  and renewing the operating  licenses at Calvert
Cliffs. The operating licenses expire in 2014 for Unit 1 and in 2016 for Unit 2.
We estimate these Calvert Cliffs costs to be:

    o   $34 million in 1999,
    o   $40 million in 2000, and
    o   $66 million in 2001.

    We estimate that during the two-year period 2002 through 2003, we will spend
an additional $150 million to complete the  replacement of the steam  generators
and extend the  operating  licenses  at Calvert  Cliffs.  We discuss the license
extension  process  further  in the  "Other  Matters  - Calvert  Cliffs  License
Extension" section of BGE's 1998 Annual Report on Form 10-K.

    If we do not replace the steam  generators,  we estimate that Calvert Cliffs
could not operate for the full term of its current operating licenses. We expect
the steam generator  replacements to occur during the 2002 refueling  outage for
Unit 1 and during the 2003 outage for Unit 2.


                                       30


    Additionally,  our estimates of future  electric  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   $33 million in 1999,
    o   $60 million in 2000, and
    o   $52 million in 2001.

    We discuss the NOx regulations in the "Environmental Matters" section of the
Notes to Consolidated Financial Statements on page 13.

    During the twelve months ended  September 30, 1999,  our utility  operations
provided  about  92% of the  cash  needed  to  meet  its  capital  requirements,
excluding cash needed to retire debt and redeem preference stock.

    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.

    During the three years from 1999 through 2001, we expect utility  operations
to  provide  about  115% of the cash  needed to meet its  capital  requirements,
excluding cash needed to retire debt and redeem preference stock.

    When BGE cannot meet utility capital requirements internally, BGE sells 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,  the  retirement  of debt,  and
payments of interest and dividends is expected from internally  generated funds,
commercial paper issuances,  available capacity under credit facilities,  and/or
the issuance of long-term  debt,  trust  securities,  or  preference  stock.  At
September 30, 1999 the Federal Energy  Regulatory  Commission has authorized BGE
to issue up to $700  million  of  short-term  borrowings,  including  commercial
paper.  To support its commercial  paper  program,  BGE maintains $83 million in
annual  committed  bank lines of credit and has $100  million in bank  revolving
credit  agreements.  In addition,  BGE has access to interim  lines of credit as
required from time to time to support its outstanding commercial paper.


Capital Requirements of Our Diversified Businesses
- --------------------------------------------------
    We expect to expand  certain of our energy  services  businesses.  This will
require additional funding for:

    o   growing our power marketing and trading business,
    o   the development and acquisition of power projects, as well as loans made
        to project entities, and
    o   funding for construction of cooling system projects.

    The  investment  requirements  exclude  Constellation  Power Source,  Inc.'s
commitment to contribute up to $175 million in equity to fund its  investment in
Orion Power  Holdings,  Inc. Orion acquires  electric  generating  plants in the
United States and Canada.  To date,  Constellation  Power Source has funded $104
million of this commitment.

    Our diversified  businesses have met their capital  requirements in the past
through borrowing,  cash from their operations,  sales of receivables,  and from
time to time, equity contributions from BGE.

    Future  funding  for the  expansion  of our energy  services  businesses  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. BGE Home Products & Services may also
meet capital requirements through sales of receivables.

    At September 30, 1999,  Constellation  Energy has a commercial paper program
where  it can  issue  up to  $500  million  in  short-term  notes  to  fund  its
diversified businesses.  To support its commercial paper program,  Constellation
Energy  maintains  a $25  million  committed  bank line of credit and has a $135
million  revolving  credit  agreement,  under which it 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. Our
diversified  businesses  also have  revolving  credit  agreements  totaling $135
million to provide additional liquidity for short-term financial needs.

    If we can get a reasonable  value for our real estate  projects,  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.

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 13 and in BGE's 1998  Annual  Report on Form 10-K
under  "Item  1.  Business  -  Environmental  Matters."  These  details  include
financial  information.  Some of the  information  is  about  costs  that may be
material.

    We have not experienced any significant year 2000 problems to date and we do
not expect any significant problems to impair our operations as we transition to
the new century.  However,  due to the magnitude and complexity of the year 2000
issue, even the most  conscientious  efforts cannot guarantee that every problem
will be found and  corrected  prior to January 1, 2000.  We believe  that all of
BGE's  "mission  critical"  systems for electric and gas production and delivery
are year 2000 ready. Mission critical systems include BGE's:

    o   electric  generating  plants,  including  Calvert  Cliffs  Nuclear Power
        Plant,
    o   energy distribution systems,
    o   natural gas delivery system, and
    o   mission critical applications supporting these systems.

     Please refer to "Forward Looking Statements" on page 38.

Utility Business
- ----------------
    We established a year 2000 Program  Management Office (PMO). Based on a work
plan developed by the PMO, we targeted the following six key areas:

    o   digital systems (devices with embedded microprocessors such as power
        instrumentation, controls, and meters),
    o   telecommunications systems,
    o   major suppliers,
    o   information technology  applications (our customer,  business, and human
        resources information systems),
    o   computer hardware and software infrastructure, and
    o   contingency plans.

    Of these  areas,  digital  systems  have the most  impact on our  ability to
provide  electric  and gas service.  Telecommunications,  major  suppliers,  and
certain information  technology  applications also impact our ability to provide
electric and gas service.

Year 2000 Project Phases
- ------------------------
    Our year 2000 project is divided into two phases:

    o   Phase I - initial assessment and detailed analysis, and
    o   Phase  II  -  testing,  remediation,   certification,   and  contingency
        planning.

    Phase I involved  conducting  an  inventory  of all systems and  identifying
appropriate  resources.  We identified the following  appropriate  resources for
each system or piece of equipment:

    o   BGE employees familiar with each system or piece of equipment,
    o   specialized contractors, and
    o   specific vendors.

    Phase I also included  developing  action plans to ensure that the key areas
identified  above are year 2000 ready. The action plans for each system or piece
of equipment included:

    o   our budget,
    o   schedules for Phase I and II, and
    o   our remediation approach - repair, upgrade, replace or retire.


                                       32


    In evaluating our risks and estimating our costs, we utilized employees with
expertise in each line of business to perform the  activities  under Phase I. We
believe our employees are the most familiar with their systems or equipment and,
therefore, provided a reliable estimate of our risks and costs.

    Phase II included converting and testing all of our systems. Each system was
tested by those employees used in Phase I following formal guidelines  developed
by the PMO. Each system or piece of equipment was then certified by a tester and
the PMO,  following  testing  guidelines  developed  with  the  help of  outside
consultants.  We  received  an  independent  Year 2000  readiness  review of our
processes and systems.  Phase II also included  identifying  our major suppliers
and  developing  contingency  plans.  We have  identified  our mission  critical
suppliers  and have  assessed  their year 2000  readiness  through  surveys  and
interviews.  We believe that our mission critical  suppliers (for example,  coal
suppliers  and  natural gas  pipeline  suppliers)  are year 2000  ready.  We are
completing the readiness review of our non-mission  critical  suppliers  through
surveys.

Contingency Planning
- --------------------
    Year  2000  operational  contingency  plans  have been  developed  utilizing
employees  familiar  with  the  operations  in each  area of our  business.  The
individual  plans are integrated  into a  corporate-wide  Year 2000  Contingency
Plan.  Associated  staffing plans have been completed  identifying all essential
personnel needed on-site for the rollover  weekend  (December 31, 1999 - January
1,  2000) to deal  with any  problems,  if they  should  occur.  BGE will have a
corporate  command center  staffed  during the rollover  weekend to serve as the
communication  hub for year 2000 status  information for BGE and all diversified
businesses.  The center will have two-way communications with the electric, gas,
retail services,  nuclear, and information technology operations command centers
for the purpose of collecting information and coordinating responses. The center
will also have two-way  communications  with the Maryland  Emergency  Management
Agency  and  local  emergency  operation  centers  in BGE's  service  territory.
Detailed coordination of the plans will continue,  and personnel will be trained
in order to provide for a smooth transition.

    The year  2000  contingency  plans  were  developed  using  the  contingency
guidelines  issued by the Nuclear  Energy  Institute  (which are endorsed by the
Nuclear Regulatory  Commission),  the contingency guidelines issued by the North
American Electric Reliability Council (NERC), and guidance from consultants.

    We have  addressed the impact of electric power grid problems that may occur
outside of our own electric  system.  We developed year 2000 electric power grid
impact   contingency   plans  through  our  various   electric   interconnection
affiliations and continue to refine them. The PJM  interconnection  drafted year
2000 operational  preparedness plans and restoration  scenarios and continues to
coordinate  and  develop  these  plans  during  the  fourth  quarter  of 1999 in
cooperation with NERC. The NERC continues to perform monthly  assessments of the
electric utility industry to communicate the readiness of the national  electric
grid for year 2000.

    On April 9, 1999, we  participated  in a NERC  sponsored  drill,  along with
other North  American  electric bulk operating  utilities.  The drill focused on
testing  backup  voice  and data  communications  and  protocols.  The drill was
successful  as it  demonstrated  our  ability to operate  the bulk power and gas
distribution  systems  reliably  during a  partial  loss of  telephone  and data
communications.

    On June 2, 1999, we conducted a successful test on our energy control system
and its interface  with the PJM.  This system  monitors and controls the flow of
electricity on BGE's electric grid.

    On September 8-9, 1999, we participated in the second NERC sponsored  drill.
The focus of this drill was a  simulation  of the  rollover to the year 2000 for
the  electric  utility  industry.  BGE  expanded the drill to include all of its
business areas. The drill was successful as it demonstrated our understanding of
our Year 2000  Operational  Contingency  Plan and our ability to operate gas and
electric systems with limited voice and data communications.

    Through the Electric  Power  Research  Institute  (EPRI),  an  industry-wide
effort was established to deal with year 2000 problems affecting digital systems
and equipment used by the nation's electric power companies.  Under this effort,
participating  utilities  assessed  specific  vendors'  system problems and test
plans.  These  assessments  have  been  shared  by the  industry  as a whole  to
facilitate year 2000 problem solving.

    BGE joined the American Gas  Association  (AGA) in an initiative  similar to
the one with NERC to facilitate  year 2000 problem  solving among gas utilities.
The AGA and its affiliates  performed  quarterly  assessments of the gas utility
industry to communicate the readiness of its members for the year 2000.

Current Status
- --------------
    The most reasonably likely worst case scenario faced by our utility business
is a  localized  interruption  in  providing  electric  and gas  service  to our
customers.  We cannot predict the impact of any  interruption  on our results of
operations, but the impact could be material.

    For all  systems  and  equipment,  both  mission  critical  and  non-mission
critical, we have completed Phase I and II.

Costs
- -----
    In the  following  table,  we show the  breakdown of our total costs between
normal  system   replacements   that  will  be  capitalized   (included  in  the
Consolidated  Balance  Sheets) and the costs that will be expensed  (included in
our Consolidated  Statements of Income) through operations and maintenance (O&M)
cost. We also show the breakdown of non-incremental  (previously included in our
information technology budget) and incremental O&M cost:

    The costs  incurred in 1996 and 1997 were for Phase I. The costs incurred in
1998 were for Phases I and II. Cost  incurred in 1999 and 2000 will be for Phase
II. In 1998, we had the  equivalent  of  approximately  110 full-time  employees
assigned to our year 2000 project.  We have had a similar level of commitment of
resources during 1999.

Diversified Businesses
- ----------------------

Overview
- --------
    Our diversified businesses have established year 2000 task forces to address
their year 2000  issues.  As the  assessments  were  completed,  the  businesses
developed  action  plans to prepare  their  systems  for the year 2000.  Outside
consultants have been retained by several of our diversified  businesses to help
complete the initial  assessment and detailed  analysis phase,  and to assist in
the testing,  remediation,  and certification phase of their year 2000 projects.
The action plans  developed  are similar to those used by our utility  business,
including a test certification process. All systems are expected to be certified
by December 1999.

    In  evaluating  their risks and  estimating  their  costs,  our  diversified
businesses utilized employees with expertise in each line of business to perform
initial assessments.  We believe our diversified  businesses'  employees are the
most  familiar  with their  systems or equipment  and  therefore  will provide a
reliable estimate of our risks and costs.

    The progress of our diversified  businesses' year 2000 projects are reviewed
by their year 2000  project  task  forces in monthly  status  meetings  with the
personnel  responsible for each project and their supervision.  Monthly progress
is also monitored by senior management for each business and monthly updates are
provided to Constellation Energy senior management.

Contingency Planning
- --------------------
    Each of our diversified  businesses are developing  contingency plans, which
are expected to be completed by December 1999.

Current Status
- --------------
    The most reasonably likely worst case scenarios faced by our energy services
businesses  and our  other  diversified  businesses  are  discussed  on page 35.
However, if any of these scenarios actually occurred, the impact is not expected
to be material to our consolidated financial results.


                                       34


Energy Services
- ---------------
    The most  reasonably  likely worst case  scenarios  for any one of our power
projects would be:

    o   a  shutdown  of the  plant's  systems  (most  of which  can be  manually
        overridden),
    o   inability of the purchasing utility to take the plant's power, or
    o   failure of critical suppliers.

    Personnel at each plant have completed their  assessment of their particular
year 2000 issues and have substantially completed the testing,  remediation, and
certification phase of their year 2000 project. In Latin America,  personnel are
focused on assessing  the year 2000  readiness of  suppliers  and are  preparing
contingency plans where necessary.

    For our power  marketing  and trading  business and our energy  products and
services  business,  the most  reasonably  likely worst case  scenario  would be
encountering  any Internet access problems with trading  partners,  transmission
service  providers,  independent system operators,  power exchanges,  or various
electronic  bulletin boards. Each of these businesses has three Internet service
providers for alternate  routing to critical Internet sites necessary to perform
day-to-day business functions. Both have completed all phases of their year 2000
projects.

    For our home products and commercial  building  systems  business,  the most
reasonably  likely worst case  scenarios  would be any  interruption  in billing
customers  or  renewing  maintenance  contracts.  This  business  completed  the
assessment  and detailed  analysis  phase and has  substantially  completed  the
testing, remediation, and certification phase of its year 2000 project.

Other Diversified Businesses
- ----------------------------
    The  most   reasonably   likely  worst  case  scenarios  for  our  financial
investments  business  would be a  breakdown  in the  systems of the  brokers or
safekeeping  banks  which it uses to trade,  or the  failure  of its  investment
managers'  computer  programs  that set  investment  strategy.  This business is
monitoring  the year  2000  readiness  of its  banks,  brokers,  and  investment
managers.

    For  our  real  estate  and  senior-living  facilities  business,  the  most
reasonably  likely worst case  scenario is a failure of the systems that support
the health,  safety,  and welfare of residents in the senior-living  facilities.
Personnel  at  each  senior-living   facility  are  involved  in  assessing  its
particular year 2000 issues and have a consultant  coordinating the overall year
2000 activity.  This business  completed the  assessment  and detailed  analysis
phase  and  has   substantially   completed   the  testing,   remediation,   and
certification phase of its Year 2000 project.

Costs
- -----
    We estimate our total year 2000 costs for our power projects  business to be
approximately  $4.2  million,  of which $1.2 million is related to our year 2000
efforts for our Panamanian electric  distribution  company.  The total estimated
year 2000 costs for our remaining diversified  businesses are approximately $2.8
million.

Accounting Standards Issued
- ---------------------------
    In July 1999, the Financial  Accounting  Standards Board issued Statement of
Financial  Accounting  Standards  (SFAS)  No.  137  regarding  the  delay of the
effective date for SFAS No. 133 on derivatives and hedging. This standard delays
the effective  date by one year and  therefore,  we must adopt the provisions of
SFAS No. 133 in our financial statements for the quarter ended March 31, 2001.



                                       35



Item 3. Quantitative and Qualitative Disclosures About Market Risk


    We discuss the following information related to our market risk:

    o   quarterly  financing  activities in the Notes to Consolidated  Financial
        Statements on page 12, and
    o   trading activities of our power marketing and trading business in the
        "Power  Marketing and Trading"  section of  Management's  Discussion and
        Analysis on page 26.

    Under the  Restructuring  Order,  BGE will provide standard offer service to
customers at fixed rates over various time periods during the transition period,
and  the  electric  fuel  rate  will be  discontinued  effective  July 1,  2000.
Additionally, upon receipt of all regulatory approvals, BGE will transfer all of
its generating  assets to nonregulated  subsidiaries of Constellation  Energy at
that time. As a result of these provisions of the Restructuring  Order, BGE will
be subject to market risk associated with acquiring  energy to provide  standard
offer service,  and  Constellation  Energy's  nonregulated  subsidiaries will be
subject to market risk associated with the sale of energy from their  generating
assets.  At this time, we cannot  estimate the financial  risks  associated with
this transition.  However, these financial risks could have a material impact on
our financial position or our results of operations.

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, 22 of these cases were settled for amounts that were immaterial.

    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
140 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.

Waste Disposal
- --------------
    As  previously  reported  in our 1998  Annual  Report on Form 10-K in United
States v. Keystone  Sanitation Company, et al., BGE and other defendants entered
into a settlement  with the  Environmental  Protection  Agency for an immaterial
amount in regard to  contamination of the Keystone  Sanitation  Company landfill
Superfund site in Adams County, Pennsylvania in 1997. On September 10, 1999, the
U.S.  District  Court for the Middle  District  of PA approved  the  settlement,
ending BGE's involvement with the site.
