                        REPORT OF INDEPENDENT ACCOUNTANTS

To the Plan Administrator of the
Constellation Energy Group, Inc.
Employee Savings Plan


We have audited the accompanying statements of net assets available for benefits
with fund information of the  Constellation  Energy Group, Inc. Employee Savings
Plan (the Plan),  formerly  the  Baltimore  Gas and  Electric  Company  Employee
Savings  Plan,  as of December  31, 1999 and  December  31, 1998 and the related
statements of changes in net assets available for benefits with fund information
for the years then ended.  These financial  statements are the responsibility of
the  Plan's  management.  Our  responsibility  is to express an opinion on these
financial statements based on our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provides a reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material  respects,  the net assets available for benefits of the Plan as of
December 31, 1999 and 1998, and the changes in net assets available for benefits
for the years  then  ended in  conformity  with  generally  accepted  accounting
principles.

Our audits  were  conducted  for the  purpose of forming an opinion on the basic
financial  statements taken as a whole.  The supplemental  schedule of financial
information for the year ended December 31, 1999 is presented for the purpose of
additional analysis and is not a required part of the basic financial statements
but is supplementary information required by the Department of Labor's Rules and
Regulations for Reporting and Disclosure  under the Employee  Retirement  Income
Security  Act of 1974.  The fund  information  in the  statements  of net assets
available for benefits and the statements of changes in net assets available for
benefits is presented for purposes of additional analysis rather than to present
the net assets  available  for benefits and changes in net assets  available for
benefits for each fund. The supplemental  schedule is the  responsibility of the
plan's  management.  The  supplemental  schedule and fund  information have been
subjected to the auditing procedures applied in the audit of the basic financial
statements  and, in our opinion,  are fairly stated in all material  respects in
relation to the basic financial statements taken as a whole.

                              EMPLOYEE SAVINGS PLAN
                          NOTES TO FINANCIAL STATEMENTS


1. GENERAL DESCRIPTION OF THE PLAN

Baltimore  Gas and Electric  Company  (BGE)  established  the  Baltimore Gas and
Electric  Company  Employee  Savings  Plan and Trust  Agreement on July 1, 1978.
Effective April 30, 1999, BGE  shareholders  approved the formation of a holding
company - Constellation  Energy Group,  Inc. (the Company) and the Baltimore Gas
and Electric Company Employee Savings Plan was amended,  restated and renamed as
the Constellation Energy Group, Inc. Employee Savings Plan (Plan). There were no
other  significant  Plan changes made at that time.  T. Rowe Price Trust Company
(T. Rowe Price) is the trustee  (Trustee).  In  addition,  TRP  Retirement  Plan
Services, Inc., is the provider of administrative services for the Plan.

The Plan is subject to the provisions of the Employee Retirement Income Security
Act of 1974 (ERISA).  Employees become eligible to make  contributions one month
after date of hire. After meeting this eligibility requirement, participants are
allowed to contribute up to 15% of their  eligible pay through  regular  payroll
deductions,  under a  deferred  compensation  option  and/or  a  thrift  option.
Participant  contributions  under the deferred  compensation option are excluded
from current year's taxable income, whereas participant  contributions under the
thrift  option are  included  in current  year's  taxable  income.  The  Company
contributes   one-half  of  the  first  6%  of  eligible  pay   contributed   by
participants.

The Plan accepts rollovers of employees'  eligible rollover  distributions  from
other qualified plans.

There are eleven investment fund choices offered for participant  contributions:
the Constellation Energy Common Stock Fund (formerly the BGE Common Stock Fund),
the Interest  Income Fund and nine mutual  funds.  The  Interest  Income Fund is
managed by T. Rowe Price Stable Asset Management,  Inc. The mutual funds consist
of the T. Rowe Price Balanced Fund, the T. Rowe Price Equity Income Fund, the T.
Rowe Price  Equity Index 500 Fund,  the T. Rowe Price Growth Stock Fund,  the T.
Rowe Price  International Stock Fund, the T. Rowe Price Mid-Cap Growth Fund, the
T. Rowe Price New Horizons  Fund,  the T. Rowe Price New Income Fund, and the T.
Rowe Price Small Cap Value Fund (mutual funds).  All Company  contributions  are
initially invested by the Trustee in the Constellation Energy Common Stock Fund.


                                       11



1. GENERAL DESCRIPTION OF THE PLAN (Continued)

Participant and Company matching contributions are sent, each pay period, to the
Trustee, who invests participant contributions as designated,  either in (1) the
Constellation  Energy Common Stock Fund for the purchase (on the open market) or
other  acquisition  (as described in Note 2) of shares of the  Company's  common
stock; (2) the nine T. Rowe Price mutual funds; or (3) the Interest Income Fund,
as more fully described below.

Dividends and earnings  received on any shares held in  participants'  accounts,
except for the  shares of Company  common  stock  held in their  employee  stock
accounts,  whether in the Constellation  Energy Common Stock Fund, or the mutual
funds are automatically  used to purchase or otherwise acquire additional shares
for  reinvestment  in  the   corresponding   fund,  and  all  earnings  on  each
participant's   investment  in  the  Interest  Income  Fund  are   automatically
reinvested in that fund.

Dividends  received on shares of Company  common  stock held in a  participant's
employee  stock  account  are  invested  by  the  Trustee  in   income-producing
investments. Annually, a check is sent to the participant representing the total
dividends  credited to the  participant's  employee  stock  account.  Any income
earned on the  dividends  is not paid out  annually,  but is used to purchase or
otherwise acquire  additional shares of Company common stock for reinvestment in
the participant's employee stock account.

The total  number  of  common  stock or mutual  fund  shares  purchased  for any
participant depends upon: (1) the participant's  eligible pay; (2) the amount of
the  participant's  eligible  pay that is  contributed;  (3) the  amount of that
contribution  which is designated  for  investment in the  Constellation  Energy
Common  Stock Fund or the  mutual  funds;  (4) the  amount of  Company  matching
contributions  invested in the  Constellation  Energy Common Stock Fund; (5) the
reinvested  dividends and earnings on each investment fund; and (6) the price of
common stock or mutual fund shares, at the time of purchase, for each investment
fund.

1. GENERAL DESCRIPTION OF THE PLAN (Continued)

Amounts  held in the Interest  Income Fund are  invested in contracts  issued by
insurance   companies  or  other  financial   institutions  and  in  short  term
investments.  Each contract specifies a fixed or variable rate of interest for a
certain period of time. The interest rate earned by the Interest  Income Fund is
a blend of the rates under the various  investments.  The annual effective rates
for 1999 and 1998 were 6.20% and 6.16%,  respectively.  The  crediting  interest
rates for the  investment  contracts as of December 31, 1999 and 1998 were 5.74%
and  5.94%,  respectively.  At  December  31,  1999  and  1998,  there  were  no
investments  in the  individual  contracts of any issuer in the Interest  Income
Fund which exceeded 5% of net assets available for benefits.  Contracts included
in the Interest  Income Fund have been reported at their contract  value,  which
approximates  fair market value.  All the  investments in this fund are held for
purposes other than trading.

Participants have the right, once a month, to change the amount of their payroll
deductions.  Participants  also have the right to change,  on a daily basis, the
percentage of their future  contributions  being  invested in each of the eleven
investment funds as provided in the Plan.

In addition,  participants are allowed to initiate, on a daily basis, a transfer
of the  value of their  contributions,  including  earnings,  among  the  eleven
investment funds. Furthermore, as of the beginning of the calendar year in which
participants  reach age 56, they may initiate,  on a daily basis,  a transfer of
the value of their Company  contributions  and employee  stock account among the
eleven investment funds.

Under a loan  program,  participants  may borrow up to  one-half  of their total
account balance, with a minimum of $1,000 and a maximum of $50,000. Participants
may elect up to five  years to repay the loan,  unless  the loan is used for the
purchase  of a  principal  residence,  in which case they may elect up to thirty
years  for  repayment.  Participants  are  allowed  to  have  up  to  two  loans
outstanding  at any time.  Principal  and  interest are repaid  through  regular
payroll  deductions or by direct payment.  The interest rate on amounts borrowed
is set at the time the loan is executed  and remains in effect for the  duration
of the loan.  The interest  rate for loans is equal to the prime rate plus 1% on
the last day of the month preceding the month the loan is initiated.

The Plan allows participants to postpone, until withdrawal or distribution,  any
income  tax  liability  on  (1)  all  Company  contributions;   (2)  participant
contributions under the deferred  compensation option; and (3) earnings on their
contributions and Company  contributions.  Participant  contributions  under the
thrift option are included in current year's taxable income.

                                       13



1. GENERAL DESCRIPTION OF THE PLAN (Continued)

Withdrawals  of  thrift  contributions  and  Company  contributions,   including
earnings,  are allowed to be initiated on a daily basis. All contributions  held
in participants' accounts are immediately 100% vested. However, participants who
withdraw unmatured basic  contributions  (contributions of up to the first 6% of
the  participant's  eligible  pay that had not remained in the Plan for two full
calendar years) are suspended from making payroll  contributions to the Plan for
twelve months.

Distributions  to  participants  who retire or terminate  active  employment are
automatically   deferred  until  they  either  reach  age  65  or  cease  active
employment,  whichever  is  later,  unless  they  request  an  earlier  or later
distribution.  Generally, participants who reach age 70 1/2 must begin receiving
their Plan  distribution by April 1 of the following year.  Furthermore,  active
employees who attain age 59 1/2 may request to receive a  distribution  of their
deferred compensation account balances.

The Plan is administered by the Director - Benefits, Human Resources Division of
Constellation  Energy Group, Inc., as Plan  Administrator.  Administrative  fees
charged by institutions, which issue contracts for the Interest Income Fund, are
reflected in the effective  rate earned by the fund. All other fees and expenses
of the Plan,  including those of the Trustee, are currently paid by the Company.
Brokerage  fees,  commissions  and transfer taxes  associated with the purchase,
sale, or transfer of shares of common stock for the Constellation  Energy Common
Stock Fund and mutual fund  shares for the nine mutual  funds are borne by those
funds.

Although  it has not  expressed  any intent to do so, the  Company has the right
under the Plan to discontinue its contributions at any time and to terminate the
Plan subject to the provisions of ERISA.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The financial  statements of the Plan are prepared  under the accrual  method of
accounting.

Shares of common  stock  for  participant  contributions  and  Company  matching
contributions  currently are purchased for the Constellation Energy Common Stock
Fund on the open market,  through new issuances or by other acquisition.  Mutual
fund shares for the T. Rowe Price Mutual Funds are purchased on the open market,
except the Trustee may purchase from time to time


                                       14



2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

a small  number of shares at  current  market  value  from  participants  making
withdrawals or interfund transfers or obtaining loans from the Plan. The cost of
shares  sold from the  Constellation  Energy  Common  Stock Fund and the T. Rowe
Price  Mutual  Funds,  as a result of  participant  distributions,  withdrawals,
interfund transfers or loans, is determined under the average cost method.

Withdrawals and distributions to participants are recorded when paid.

Leveraging  provisions are included in the Plan, but these  provisions  have not
yet been utilized.

Shares of common stock in the Constellation  Energy Common Stock Fund held by T.
Rowe Price Trust Company are valued as of December 31, 1999 and 1998,  using the
quoted  closing market price as reported by the  "NYSE--Composite  Transactions"
published in the eastern edition of The Wall Street Journal.  Mutual fund shares
held in the T. Rowe Price Mutual  Funds,  are valued as of December 31, 1999 and
1998  respectively,  using the net asset value price of such shares as quoted by
the "Mutual Fund  Quotations"  for such date in the eastern  edition of The Wall
Street Journal.  Participant  loans are valued at cost, which  approximates fair
value.

The Plan's investments are stated at fair value except for the various contracts
issued  by  insurance  companies  or other  financial  institutions,  under  the
Interest  Income  Fund,  which are fully  benefit-responsive  and are  stated at
contract   value.   Contract  value  is  equal  to  the  aggregate  of  the  net
contributions and earnings thereon.

The Plan  presents  in the  Statement  of Changes in Net  Assets  Available  for
Benefits  the  net  appreciation   (depreciation)  in  the  fair  value  of  its
investments   which   consists  of  realized  gains  or  losses  and  unrealized
appreciation (depreciation) on those investments.

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

We adopted Statement of Position (SOP) No. 99-3, Accounting for and Reporting of
Certain Defined  Contribution  Plan  Investments and Other  Disclosure  Matters,
effective   January  1,  1999.  SOP  99-3  amends  reporting   requirements  for
participant and nonparticipant-directed  investments in the financial statements
and related notes. We have met these requirements for the periods presented.
