                        COMMON QUESTIONS ABOUT THE PLAN

As you  review  this  prospectus,  you  will  notice  that  this  plan  offers a
convenient and economical way to increase your ownership of Constellation Energy
common stock.  The plan also allows a convenient way for you to keep your shares
with us under a custodial (safekeeping) agreement.  Below are some questions and
answers about the key features of our Shareholder Investment Plan:

1.   WHO IS ELIGIBLE TO PARTICIPATE IN THE SHAREHOLDER INVESTMENT PLAN?

     Any  owner of our common stock.

2.   DO I HAVE TO REINVEST  ALL THE  DIVIDENDS ON MY COMMON STOCK IF I ENROLL IN
     THE PLAN?

     No.  You may reinvest all, part or none of your common stock dividends.

3.   MAY I PURCHASE ADDITIONAL SHARES OF COMMON STOCK THROUGH THE PLAN FROM TIME
     TO TIME?

     Yes. You may invest up to $100,000 in additional  shares of common stock in
     any calendar year. The minimum investment is $25.

4.   MAY I DEPOSIT MY STOCK IN THE PLAN?

     You may deposit,  free of any service charges, your common stock to be held
     by us as custodian.


                                       3




5.   WILL MY DIVIDENDS AND OPTIONAL CASH INVESTMENTS BE FULLY INVESTED IN COMMON
     STOCK?

     Yes. Both dividends and optional cash  investments  will be used in full to
     purchase  additional  common stock. As a result,  your plan account will be
     credited with whole shares and a fractional  share.  However,  if you close
     your plan  account,  any  fractional  share held will be paid out to you in
     cash.

6.   HOW ARE SHARES PURCHASED FOR MY PLAN ACCOUNT?

     At our option,  shares for your plan  account are  purchased  either on the
     open market or directly from Constellation Energy.

7.   HOW IS THE PRICE OF SHARES BOUGHT OR SOLD DETERMINED?

     Prices are calculated differently for shares:
    
     -    bought in the open market,

     -    bought directly from Constellation Energy, and
   
     -    sold.

     Shares Bought on the Open Market
     --------------------------------
     For shares  bought on the open market,  the price will be calculated as the
     weighted  average price of all shares bought for the  investment  date. The
     price will include any brokerage commission and fees.

     Shares Bought Directly From Us
     ------------------------------
     For shares bought directly from  Constellation  Energy, we average the high
     and low sale  prices of our common  stock on the  investment  date.  If our
     common stock is not traded on the  investment  date, we use the prices from
     the previous  trading day. There are no brokerage  commissions or fees when
     shares are purchased from us.

     For Shares Sold
     ---------------
     For shares sold, the price will be calculated as the weighted average price
     of all plan  shares  sold on the sale  date.  The price  will  include  any
     brokerage commission and fees.

8.   WHEN ARE DIVIDENDS REINVESTED?

     We reinvest  dividends on the first business days of January,  April,  July
     and October.

9.   WHEN ARE OPTIONAL CASH INVESTMENTS CREDITED TO MY PLAN ACCOUNT?

     Optional  cash  investments  are credited to your plan account on the first
     business day of the month after we receive them.

10.  ARE THERE  BROKERAGE  COMMISSIONS  AND FEES FOR  BUYING OR  SELLING  SHARES
     THROUGH THE PLAN?

     Yes. Brokerage commissions and fees are charged on shares bought or sold in
     the open  market.  These fees are based on the  number of shares  bought or
     sold and the price per share.  Brokerage  commissions and fees are expected
     to be no more than 4 cents per share.  When the plan buys  shares  directly
     from Constellation Energy, there are no commissions or fees.

11.  ARE THERE ANY OTHER FEES FOR BUYING AND SELLING SHARES THROUGH THE PLAN?

     Yes.  We charge a $5  processing  fee for each sale of plan shares for your
     plan account.  There are no additional fees for buying shares for your plan
     account.

                                       4




12.  WHEN WILL I RECEIVE AN ACCOUNT STATEMENT?

     We will send you a statement  for every month in which there is activity in
     your plan account. Activity in your plan account includes when:

     -    we reinvest a dividend for you,
     
     -    you remit an optional cash investment,
     
     -    you deposit shares under the custodial feature of the plan,

     -    you withdraw or transfer shares, or

     -    you terminate your participation.
    
     In addition,  we will send you an annual statement in January detailing all
     account activity during the prior year.  PLEASE KEEP YOUR  STATEMENTS.  YOU
     WILL NEED THEM FOR TAX PURPOSES.

13.  MAY I TRANSFER SHARES FROM ONE ACCOUNT TO ANOTHER?

     Yes. We will send the required form upon request.

14.  WILL  CONSTELLATION  ENERGY ISSUE A STOCK  CERTIFICATE FOR THE SHARES IN MY
     ACCOUNT?

     If you send us a written request, we will issue you a stock certificate. We
     do not issue a certificate for a fractional share.

15.  IF MY SHARES ARE HELD IN "STREET NAME" BY A STOCKBROKER,  MAY I PARTICIPATE
     IN THE PLAN?

     Yes. You may request your broker to participate on your behalf. However, by
     participating  in this manner,  you'll only be able to reinvest  dividends.
     You won't be able to participate in any other plan feature.  Alternatively,
     you may ask your  broker  to  transfer  shares  into  your  name so you can
     participate  directly with us and take  advantage of ALL the plan features.
     Different   brokers  have   different   conditions   and   procedures   for
     participating  in the plan on your behalf or for  transferring  shares into
     your name. You should contact your broker if you have questions about this.

16.  ARE CONSTELLATION ENERGY DIVIDENDS TAXABLE INCOME?

     Yes.  Dividends are taxable income  whether  reinvested or paid in cash. We
     will send you an IRS Form  1099-DIV  each  January  showing  your  dividend
     income for the previous year.

17.  MAY I  RECEIVE  DIVIDENDS  IN CASH FOR  SHARES I HOLD IN STOCK  CERTIFICATE
     FORM?

     Yes.  You do  not  have  to  reinvest  dividends  on  shares  you  hold  in
     certificate form.

18.  MAY I RECEIVE DIVIDENDS IN CASH FOR SHARES HELD IN MY PLAN ACCOUNT?

     Yes. You are not required to reinvest  dividends on the shares held in your
     plan account.

19.  IS INTEREST PAID ON ANY CASH HELD BY THE PLAN PRIOR TO INVESTMENT?
 
     No. We do not pay interest on any funds held by us prior to  investment  in
     additional  common stock. If you send in an optional cash investment  early
     in the month,  it is not invested in your account until the first  business
     day of the following month.


                                       5




20.  MAY I DETERMINE AT WHAT PRICE SHARES ARE BOUGHT AND SOLD ON MY BEHALF?

     No.  You will  have no  control  over the  price at which  stock is  bought
     whether on the open market or from us.  Likewise,  you will have no control
     over the price at which shares are sold by the independent  agent. You will
     bear the  market  risk  associated  with  fluctuations  in the price of our
     common stock.

21.  MAY I ASK TO HAVE MY MONEY RETURNED?

     Yes. If you have sent money for an optional cash investment, that money can
     be returned to you if we receive a written  request no later than the close
     of business on the last business day of the month.


                           WHO PAYS THE PLAN'S COSTS

We pay all of the  administrative  costs of the plan.  You will pay a  brokerage
commission when the common stock is bought or sold on the open market.  When the
plan buys the common stock directly from us, you pay no brokerage commission. In
addition,  you will pay a $5  processing  fee each time you request that we sell
shares on your behalf.


                   AUTOMATIC ROLLOVER FROM BGE OR PEPCO PLAN

If you participate in either BGE's or PEPCO's dividend  reinvestment plan at the
time of the merger, you will be automatically enrolled in Constellation Energy's
plan with no changes  from how you are  enrolled  in BGE's or  PEPCO's  dividend
reinvestment plan. Your BGE or PEPCO plan shares will be automatically converted
to Constellation Energy common stock. BGE shares will be converted at a ratio of
1 for 1. PEPCO  shares will be converted at a ratio of .997 for 1. If you decide
to deposit your Constellation  common  stock with  us  (see  CUSTODY  OF  SHARES
ON PAGE 10) the dividends on those shares will be paid out or reinvested as  you
have instructed us on your most recently executed BGE,  PEPCO  or  Constellation
Energy enrollment form.  To change those instructions,  simply  send  in  a  new
Constellation Energy enrollment form. See CHANGING YOUR REINVESTMENT ELECTION on
page 8.


                           HOW TO ENROLL IN THE PLAN

You may  join  the  Constellation  Energy  plan at any  time by  completing  and
returning an enrollment  form and/or a custody form. You may request these forms
from Shareholder Services, at the appropriate number listed on page 3.

To join the plan you may choose one or more of the following:

- - -    Full or partial dividend reinvestment;
  
- - -    Making  optional cash  investments of up to $100,000 per calendar year (the
     minimum is $25 per investment) to purchase additional common stock for your
     plan account; and/or
 
- - -    Depositing your common stock certificates with us.

If you have more than one account,  for example accounts registered "John Smith"
and "John Q. Smith," you must complete a separate authorization for each account
that you wish to enroll in the plan.


                                       6



YOU ARE NOT  REQUIRED  TO  REINVEST  DIVIDENDS  IN ORDER TO MAKE  OPTIONAL  CASH
INVESTMENTS  OR DEPOSIT YOUR SHARES WITH US. YOU MAY REINVEST  DIVIDENDS ON ALL,
SOME OR NONE OF YOUR SHARES.

If your  Constellation  Energy  common stock is held for you in "street name" by
your bank or broker,  you may be able to  participate  by asking  your broker to
join the plan on your behalf to reinvest  dividends.  If you  participate in the
plan  through  your  broker,  you  will  only be able to take  advantage  of the
dividend  reinvestment  feature of the plan. You will not be able to participate
in any of the other plan  features.  Alternatively,  you may ask your  broker to
have  your  shares  transfer into  your own name, so you may participate in  the
plan directly and take advantage of all the plan features.

Contact your broker to find out what you must do for them to participate on your
behalf or to have them transfer shares into your name.


                             REINVESTING DIVIDENDS

REINVEST ALL OR PART OF YOUR DIVIDENDS

You may  reinvest  all or part of the common  stock  dividends on the shares you
hold in certificate form and/or on the shares we hold in your plan account.  Any
dividends  not  reinvested  will  be  paid  to you  by  check,  or if  you  have
authorized,  electronically deposited into your bank account. To obtain a direct
deposit form, please contact us at the appropriate number listed on page 3.

If you would like to reinvest only a portion of your dividends, you have several
options. You may elect to:

- - -    reinvest dividends only on the shares you hold in certificate form; or

- - -    reinvest dividends only on the shares held in your plan account.

You may also:

- - -    reinvest dividends only on a specific number of shares;

- - -    reinvest only a specific percentage of your dividends; or

- - -    reinvest only a specific dollar amount of your dividends.

You are not required to reinvest any of your  dividends in order to  participate
in the plan.  You may  change  your  election  as  described  in  CHANGING  YOUR
REINVESTMENT ELECTION on page 8.

WHEN ARE DIVIDENDS REINVESTED

When our Board of Directors  declares  dividends  they also set the record dates
and  payment  dates.  Both  BGE  and  PEPCO  historically  have  paid  dividends
quarterly.  The record dates are  typically the 10th day of the month before the
dividend payment date.

In order for you to begin  reinvesting  your  dividends  by one of the  dividend
payment dates, we must receive your enrollment form by the record date. If we do
not receive  your  enrollment  form by the record  date,  you will  receive your
dividend  payment  for that  quarter  in the usual  manner  (either  by check or
electronically  deposited in your bank  account).  Your  dividends  then will be
reinvested  beginning with the following dividend payment.  Please note that the
amount of any  dividends reinvested will  be reduced  by  any  amount  which  is
required to be withheld under apllicable tax or other law.


                                       7



Dividends are used to purchase  additional  shares of common stock  beginning on
the payment date.  Dividends are held in an escrow  account with a bank separate
from our other  money,  until we pay for the  shares  purchased.  The method for
determining the price of the common stock purchased with reinvested dividends is
explained under PURCHASES AND SALES OF SHARES on page 9.


                      CHANGING YOUR REINVESTMENT ELECTION

You may change your reinvestment election by giving us written instructions,  or
filling  out a new  enrollment  form or the  tear-off  portion  of your  account
statement.  In order  for a change to be  effective  for a  particular  dividend
payment  date,  we must receive your  instructions  on or before the record date
relating to the dividend payment. If we do not receive your instructions by that
record date, your instructions will not become effective until the next dividend
payment.


                           OPTIONAL CASH INVESTMENTS

HOW TO MAKE

Whether or not you reinvest  dividends,  you may purchase  additional  shares of
common  stock by making  optional  cash  investments  in any  amount  within the
following guidelines:

   Minimum Investment  -  $25
  
   Maximum Investment  -  $100,000 per calendar year

You can make  optional  cash  investments  by sending us a check or money  order
payable  to  Constellation  Energy  Corporation.   All  checks  are  subject  to
collection by us and must be in United States dollars.  DO NOT SEND CASH.

You may make your first  optional  cash  investment  by  enclosing  it with your
enrollment form. If you are already a participant, optional cash investments may
be sent in with the tear-off portion of your account statement,  or with written
instructions.  Send  investments to us at the address listed on page 3. There is
no obligation to make  optional  cash  investments,  nor do you have to make the
same size investment each time you invest.

INVESTMENTS OF LESS THAN $25 OR MORE THAN $100,000

If you send in an optional cash investment for less than $25 it will be returned
to you without  interest  as soon as  practicable.  Likewise,  if you send in an
optional cash investment for more than $100,000 in any calendar year, the excess
will be refunded to you without interest as soon as practicable.

ONE TIME EXCEPTION TO THE $25 MINIMUM INVESTMENT

For  former BGE and PEPCO  shareholders,  there is A ONE TIME  EXCEPTION  to the
requirement that optional cash investments be in an amount of at least $25. When
BGE  and  PEPCO  shareholders  exchange  their  common  stock  certificates  for
Constellation  Energy  shares,  they can choose to have any cash payout due them
from the  exchange  invested in the plan as an  optional  cash  investment.  The
choice to have these payouts invested in the plan can only be made on the Letter
of Transmittal  received from the exchange agent.  The pqyouts eligible for this
one time exception include:

- - -   any fractional share payment due a PEPCO shareholder,


                                       8



- - -   any refund in connection with the buy-up option due a PEPCO shareholder, and

- - -   any dividends held pending exchange due a BGE or PEPCO shareholder.

To take  advantage of this one time option,  you must either be a participant in
the BGE or PEPCO  dividend  reinvestment  plan, or must elect at the time of the
exchange to have your Constellation  Energy common stock shares held by the plan
as custodian.

WHEN INVESTMENTS ARE MADE

Common  stock is  purchased  and  allocated to your plan account as of the first
business day of the month after we receive your optional cash investment.  If we
receive your  investment on or after the first business day of a month,  it will
be held and invested the first business day of the following  month. WE WILL NOT
PAY INTEREST ON FUNDS PENDING INVESTMENT. Please allow sufficient time for us to
receive your optional cash investment through the mail. We need to receive it at
least one business day before the first day of a month so that your payment will
be invested timely. Optional cash investments are held in an escrow account with
a bank separate from our other money, until we pay for the shares purchased.

RETURNS

If you decide you do not want us to invest the optional cash investment you sent
us, you must notify us in writing by the last  business  day of the month before
the investment date. We then will refund your optional cash investment. However,
we will not refund the money until we have actually collected it from your bank.
Accordingly,  refunds  may be  significantly  delayed.  Once  an  optional  cash
investment  has been  invested in common  stock,  no refunds  will be made.  See
WITHDRAWALS FROM THE PLAN on page 11, or TERMINATING PARTICIPATION on page 12.


                         PURCHASES AND SALES OF SHARES

SOURCE OF PURCHASED SHARES

We may use either shares purchased from Constellation  Energy (new issue shares)
or shares purchased in the open market through the independent agent.

NO CONTROL OVER PRICES FOR SHARES BOUGHT OR SOLD

No one has the  ability  to  determine  the price at which  shares are bought or
sold.  The price of our common  stock may  fluctuate  daily  depending on market
conditions,  and we have no  control  over this.  You will bear the market  risk
associated with  fluctuations in the price of our common stock.  The independent
agent will purchase or sell shares in the open market.

INDEPENDENT AGENT

An independent agent:

- - -    is generally a bank or broker separate from the company,

- - -    is selected by the company to purchase  and sell shares of our common stock
     in the open market for plan participants, and

- - -    can be  replaced  at any time by  written  notification  from  the  company
     explaining  the  termination  of their  contract and the selection of a new
     independent agent.

                                       9



For open market  transactions,  the independent  agent  determines the market on
which the shares are bought or sold (for example, on any stock exchange,  in the
over-the-counter market, or in negotiated transactions) and the selection of the
broker or dealer through or from whom purchases and sales are made.

Even though we are currently the  administrator  of the plan, it is possible for
us to have someone else act as the plan  administrator.  If that were to happen,
that person  could also be the  independent  agent who would  purchase  and sell
shares for plan participants.

PRICE FOR SHARES PURCHASED FROM US

Purchases of common stock from us will be made on the relevant  investment date.
The price of the shares  will be  calculated  as the average of the high and low
sales prices for shares of our common stock.  In making the  calculation  we use
the prices reported by the "New York Stock Exchange  Composite  Transactions" in
the Eastern Edition of THE WALL STREET JOURNAL for:

- - -    the investment date, or

- - -    the previous  trading day if the investment  date is not a day on which our
     common stock was traded.

PRICE FOR SHARES BOUGHT OR SOLD ON THE OPEN MARKET

PURCHASE PRICE.  The purchase price will be the weighted average price per share
(plus brokerage  commissions  and fees) of the total number of shares  purchased
either with  reinvested  dividends or with  optional cash  investments  for that
investment date.  Currently,  the brokerage commissions and fees are expected to
be no higher than 4 cents per share.

The  number of  shares  of common  stock  credited  to your  plan  account  on a
particular  investment  date  (including  a  fractional  share  rounded to three
decimal  places)  will be  determined  by  dividing  the  total  amount  of your
dividends or optional cash investments by the purchase price per share.

SALES PRICE.  The sales price will be the weighted average price per share (less
brokerage  commissions and fees) of the total number of shares sold.  Usually we
process sale transactions twice a week. Currently, the brokerage commissions and
fees are expected to be no higher than 4 cents per share. In addition,  you will
be charged a $5 processing fee for each sale you request from your plan account.

The shares held in your plan account, together with all other shares held in the
plan, are represented by one or more global certificates  registered in our name
as administrator of the plan.


                                CUSTODY OF SHARES

AT THE TIME OF THE BGE AND PEPCO MERGER SHARE EXCHANGE

You may tell us on the Letter of  Transmittal  received from the exchange  agent
that you want to deposit your  Constellation  Energy  common stock into the plan
 rather than receive certificates for those shares.

AFTER THE EXCHANGE

You may take advantage of the free custodial feature of the plan at any time. To
deposit your common stock  certificates  into the plan send us the certificates,
together with:

                                       10
  


- - -    a completed  custody form,  which you may obtain from us at the appropriate
     number listed on page 3; or

- - -    your own letter of instruction.

Your letter of instruction should include:
 
- - -    your shareholder account number,

- - -    a  list  showing  the  certificate  numbers  and  number  of  shares  being
     deposited, and

- - -    the  signatures of all the owners,  which must be identical to the names on
     your  stock  certificates  and the plan  account  into which the shares are
     being deposited.

The certificates  you send to us for deposit should be sent UNSIGNED.  Send them
to the address  shown on page 3. SINCE YOUR STOCK  CERTIFICATES  ARE VALUABLE WE
URGE  YOU TO USE  REGISTERED,  INSURED  MAIL  WHEN  MAILING  YOUR  CERTIFICATES.
Replacing lost  certificates may require you to purchase a surety bond which can
be expensive, generally 2% of the value of the lost shares.

OTHER PROVISIONS OF THE CUSTODY FEATURE

When you use the custody feature of the plan, you join the plan and may elect to
use any of its features.  For example, we can reinvest all, part or none of your
dividends on the common stock held in your plan account as you direct us on your
enrollment  form.  You  can  get an  enrollment  form  by  contacting  us at the
appropriate number indicated on page 3.

The  certificates  you  deposit  with us will be  transferred  into  our name as
custodian,  and the number of shares  represented by those  certificates will be
credited to your plan account.  Thereafter,  those shares will be treated in the
same manner as any other shares held in your plan account.

The  certificate(s)  you  deposit  will  be  canceled.  Therefore,  WE  STRONGLY
RECOMMEND THAT BEFORE YOU SEND US YOUR  CERTIFICATE(S)  FOR DEPOSIT,  YOU MAKE A
PERMANENT RECORD OF EACH CERTIFICATE  NUMBER,  THE DATE ISSUED AND THE NUMBER OF
SHARES  REPRESENTED BY THE CERTIFICATE.  If you decide to sell the shares,  this
information  may become  important for tax purposes.  We are not responsible for
providing this information once the shares are deposited with us.


                            WITHDRAWALS FROM THE PLAN

FOR CASH OR A STOCK CERTIFICATE

To withdraw  all or a portion of the whole  shares held in your plan  account at
any time:

- - -    prepare written instructions; or

- - -    complete the tear-off portion of your account statement; or

- - -    complete a withdrawal  request form which you can get by  contacting  us at
     the  appropriate  number  listed on page 3.

Send the request to us at the address  shown on page 3. You may elect to receive
either a stock  certificate  for the whole shares  withdrawn or the net proceeds
from the sale of the shares. See PURCHASES AND SALES OF SHARES on page 9.

We generally process  withdrawals twice a week and send you, normally within two
weeks,  a  certificate  for the  shares  withdrawn,  or a check for the net sale
proceeds,  in  accordance  with  your  instructions.  Please  remember  that the
withdrawal of shares requires the signatures of all account owners.


                                       11



TO TRANSFER SHARES

We will transfer all or part of your shares for you at no cost. You may:

- - -    transfer shares to an existing plan account; or

- - -    establish a new plan account; or

- - -    have a stock certificate issued in another person's name.

To request a transfer of shares either:

- - -    prepare  written   instructions,   providing  the  name,  address  and  tax
     identification   number  of  the  person  to  whom  the  shares  are  being
     transferred; or

- - -    complete a withdrawal  request form which you can get by  contacting  us at
     the appropriate number listed on page 3.

Send  the  request  to us at the  address  shown  on page 3. We  cannot  issue a
certificate  for a fractional  share.  Your request  must be  accompanied  by an
executed stock assignment form (or a stock power).  All owners of the stock must
sign the stock  assignment  form and each signature must be guaranteed by a bank
or broker who has a  membership  in an approved  Signature  Guarantee  Medallion
Program.  We can provide you with a stock assignment form, or they are available
from your bank or broker.

If you transfer shares to an existing plan account,  we will reinvest  dividends
on the  transferred  shares in  accordance  with the  reinvestment  instructions
previously  given  to  us  by  the  transferee.   If  we  have  no  reinvestment
instructions,  we will pay the dividends by check until the  transferee  makes a
reinvestment  election.  If you  transfer  shares to a new plan account that you
have  established  for  someone,  we will  provide the new  participant  with an
enrollment  form.  Until the completed enrollment form is returned  to  us,  all
dividends on the transferred shares will be paid out by check.


                       EFFECT OF WITHDRAWALS AND TRANSFERS

Withdrawals or transfers from the plan do not affect your participation,  unless
you specifically elect to make a change. See CHANGING YOUR REINVESTMENT ELECTION
on page 8.

If you reinvest dividends on only a portion of your plan shares and you elect to
withdraw or transfer a portion of your plan shares, dividends on the plan shares
remaining  (up to the  number  of  shares  you  previously  had  designated  for
reinvestment) will continue to be reinvested,  unless you tell us otherwise. For
example,  if you had elected to reinvest  dividends on 50 of the 100 shares held
in your plan account and you withdraw 25 shares, the dividends  reinvested after
the  withdrawal  will  still be on 50 of the 75  remaining  shares.  Or, if  you
withdraw 75 shares, the dividends reinvested after the withdrawal will be on the
25 remaining shares held in your plan account.


                            TERMINATING PARTICIPATION

BY YOU

You may terminate your plan participation at any time by:

- - -    preparing a written request; or

- - -    completing the tear-off portion of your account statement; or


                                       12



- - -    completing a withdrawal  request form which you can get by contacting us at
     the appropriate number listed on page 3.

Send the request to us at the address shown on page 3. You will need to indicate
whether you would like a stock  certificate for the whole shares in your plan or
would like your shares sold. Generally,  we process termination requests twice a
week. We send you, normally within two weeks, a check for the net sale proceeds,
or a stock certificate for the whole shares and a check for the fractional share
held in your plan account. See PURCHASES AND SALES OF SHARES on page 9.

When you terminate participation in the plan, we pay all future dividends to you
by check or, if you have authorized,  electronically deposit them into your bank
account.

BY US

If you do not have at least one whole  share of stock in your plan  account  and
(1) you are not reinvesting dividends on the stock you hold in certificate form,
or (2) you no longer own shares  registered  in your name,  your  account may be
terminated. We will notify you in writing of the impending termination. You will
then have 30 days to make  changes  needed to keep your  account  open by either
electing to reinvest dividends, making an optional cash investment or depositing
shares under the custody feature of the plan.  Otherwise, we will terminate your
plan account.


                                  PLAN REPORTS

We will mail you an account  statement  after any month in which  there has been
activity in your account. Activity in your plan account includes when:

- - -    we reinvest a dividend for you,

- - -    you remit an optional cash investment,

- - -    you deposit shares under the custodial feature of the plan,

- - -    you withdraw or transfer shares, or

- - -    you terminate your participation.

The statement  will show all activity for the current  calendar year to date and
the total shares you hold in the plan.  In addition,  you will receive an annual
account statement each January that summarizes all your plan transactions in the
prior year.

Be sure to keep  all of your  annual  statements.  They  provide  the  necessary
information about the cost of your stock for tax purposes.  We will charge you a
$5 fee to replace an old statement.

You will  receive  copies  of all  communications  we send to our  common  stock
shareholders including our annual report, any interim reports,  notice of annual
meeting and proxy statement, and certain income tax information.


                                      COSTS

We will pay all  administrative  costs and  expenses  associated  with the plan,
except that you will pay  brokerage  commissions  and fees on all  purchases and
sales of common stock in the open market, which is expected to be no more than 4
cents per  share.  You will also pay a $5  processing  fee per  request  to sell
shares.  You do not pay any brokerage  commissions  and fees on shares of common
stock purchased directly from us.


                                       13



                         FEDERAL INCOME TAX CONSEQUENCES

DIVIDENDS

Dividends are taxed as income whether you reinvest them or receive them in cash.
Each January we will send you a Form 1099-DIV reporting dividends we paid you in
the prior year  including  dividends you reinvest and any federal  income tax we
withheld from the dividends. We will also file this form with the IRS.

Your  dividends  are subject to income tax  withholding  if you do not provide a
Form W-9 certifying (1) the accuracy of your taxpayer  identification  number or
social  security  number and (2) that you either have not received a notice from
the IRS stating that you are subject to income tax withholding,  or that you are
exempt  from  income tax  withholding.  Your  dividends  will also be subject to
income  tax  withholding  if for  any  reason  we are  instructed  by the IRS to
withhold taxes. If you are a foreign shareholder, your dividends  are  generally
subject to U.S. tax withholding at a rate determined under tax law and treaty.

SALE OF SHARES

The tax basis of shares purchased under the plan is generally the purchase price
per share including any brokerage  commissions and fees. See PURCHASES AND SALES
OF SHARES on page 9. The holding  period for shares usually begins the day after
the investment date.

You may  recognize a gain or loss when you sell  shares from your plan  account,
including  the  fractional  share.  The  amount of your gain or loss will be the
difference between the amount you received for the shares when you sold them and
the tax basis of the shares. We will send to you and the IRS each January a Form
1099-B  that  reports  the  proceeds  from the sale of any shares  (including  a
fractional share) and any federal income tax withheld.

Your sale  proceeds  will be  subject to income  tax  withholding  if you do not
provide a Form W-9  indicating  your  taxpayer  identification  number or social
security number, or we are instructed by the IRS to withhold taxes.

You will not  recognize  any taxable  income when you receive  certificates  for
whole  shares of stock.  You will  only  recognize  a gain or loss when you sell
those shares.

THIS  GENERAL TAX  DISCUSSION  IS BASED UPON OUR  UNDERSTANDING  OF THE TAX LAWS
CURRENTLY IN EFFECT. IT IS NOT INTENDED TO BE A COMPREHENSIVE EXPLANATION OF ALL
POSSIBLE INCOME TAX CONSEQUENCES  RELATED TO YOUR PARTICIPATION IN THE PLAN. YOU
SHOULD CONSULT YOUR TAX ADVISOR FOR INFORMATION  THAT MAY AFFECT YOUR INDIVIDUAL
SITUATION.


                                  MISCELLANEOUS

ASSIGNMENT OF SHARES

If you want to assign or  pledge  any  shares  held in your  plan  account  to a
creditor  or use them as  security  for a loan you must  withdraw  them from the
plan. See WITHDRAWALS FROM THE PLAN on page 11.

STOCK DIVIDENDS AND STOCK SPLITS

We will add to your plan account any shares of common stock we  distribute  as a
result of a stock


                                       14



dividend or stock split on shares of common stock in your plan account.

VOTING

You will receive one proxy card to vote both the shares you hold in  certificate
form and those  you hold in your  plan  account.  Your  shares  will be voted in
accordance with your  instructions  on your proxy card. If no  instructions  are
given, your shares will not be voted.

LIMITATION OF LIABILITY TO PLAN PARTICIPANTS

Neither we nor any of our officers,  directors, or employees,  the administrator
(if it is not us) or the independent  agent will be liable to you for any act or
omission of any act.  This  limitation  of  liability  applies  to,  among other
things,  the prices at which your shares are bought and sold,  when purchases or
sales are made, and any changes in the market price.

You  should  be aware  that  this  plan  does not  guarantee  future  dividends.
Dividends depend upon Constellation Energy's earnings,  financial  requirements,
governmental  regulations and other factors.  You must recognize that neither we
nor the  independent  agent can assure you of a profit or protect  you against a
loss on shares of common stock purchased or sold through the plan.

We have no  obligation  to  repurchase  any shares of common stock issued to you
under the plan.

MODIFICATION OR TERMINATION OF THE PLAN

We may suspend,  modify,  or  terminate  the plan or any part of the plan at any
time.  We also  have the  right to  interpret  and  regulate  the plan as may be
necessary or desirable in connection with its operation.

If we terminate the plan,  you will receive a stock  certificate  for all of the
whole  shares held in your  account and a check for the net proceeds of the sale
of any fractional share.

general corporate purposes relating to our utility business, including repayment

                  LIMITATION OF DIRECTOR AND OFFICER LIABILITY

Our charter  and by-laws say we shall  indemnify  our  directors,  officers  and
employees  to the fullest  extent  permitted  by law,  including  the advance of
expenses.  In addition,  our charter  provides,  to the extent permitted by law,
that no director or officer shall be personally  liable to Constellation  Energy
or its shareholders for money damages.

Insofar as indemnification  for liabilities  arising under the Securities Act of
1933  may  be  permitted   to   directors,   officers  or  persons   controlling
Constellation  Energy,  pursuant to the above  paragraph,  we have been informed
that in the opinion of the SEC such  indemnification is against public policy as
expressed in the Act and is unenforceable.

Item 15.  Indemnification of Directors and Officers.

      Article Seventh of the Corporation's Charter and Article VI
of  the  Corporation's By-laws provide that to the fullest extent
permitted  by applicable statutory or decisional law, as  amended
or interpreted, no director or officer of the Corporation will be
personally  liable  to  the Corporation or its  shareholders  for
monetary damages.

      Under Section 2-418 of the Maryland General Corporation Law
("MGCL"),  a Maryland corporation may indemnify any director  who
was  or  is  a party or is threatened to be made a party  to  any
threatened,  pending, or completed action,  suit  or  proceeding,
whether   civil,   criminal,  administrative   or   investigative
("Proceeding")  by reason of the fact that he  is  a  present  or
former  director of the corporation and any person who,  while  a
director of the corporation, is or was serving at  the request of
the  corporation  as  a   director, officer,   partner,  trustee,
employee,  or  agent  of another corporation, partnership,  joint
venture,  trust,   other  enterprise, or employee  benefit   plan
("Director").  Under Section 2-418(b)(1)(i)-(iii), a  corporation
may  indemnify  any  director made a party to any  proceeding  by
reason  of  service  in that capacity, unless it  is  established
that:   (i)  the act or omission of the director was material  to
the matter giving rise to the proceeding and (1) was committed in
bad  faith;  or  (2)  was  the result of  active  and  deliberate
dishonesty;  (ii)  the  director actually  received  an  improper
personal benefit in money, property, or services; or (iii) in the
case  of  any  criminal proceeding, the director  had  reasonable
cause to believe that the act or omission was unlawful.

      A  Maryland  corporation may not indemnify any Director  in
connection  with  a  Proceeding  by  or  in  the  right  of   the
corporation if the Director has been adjudged to be liable to the
corporation.   A Director or officer who has been  successful  in
the   defense  of  any  Proceeding  described  above   shall   be

                           II-1



indemnified  against reasonable expenses incurred  in  connection
with  the  Proceeding.   The  corporation  may  not  indemnify  a
Director  in respect of any Proceeding charging improper personal
benefits to the Director in which the Director was adjudged to be
liable   on  the  basis  that  personal  benefit  was  improperly
received.   Notwithstanding  the above  provisions,  a  court  of
appropriate  jurisdiction, upon application of the   Director  or
officer, may order indemnification if it determines that in  view
of  all  the  relevant circumstances, the Director or officer  is
fairly  and  reasonably  entitled  to  indemnification;  however,
indemnification with respect to any Proceeding by or in the right
of  the  corporation or in which liability was  adjudged  on  the
basis  that  personal benefit was improperly  received  shall  be
limited  to  expenses.   A  corporation  may  advance  reasonable
expenses  to a Director under certain circumstances, including  a
written undertaking by or on behalf of such Director to repay the
amount if it shall ultimately be determined that the standard  of
conduct necessary for indemnification by the corporation has  not
been met.  A corporation may indemnify and advance expenses to an
officer  of  the  corporation to the  same  extent  that  it  may
indemnify  Directors under the statute.  The indemnification  and
advancement  of expenses provided or authorized by  this  statute
may   not   be   deemed  exclusive  of  any  other   rights,   by
indemnification or otherwise, to which a Director or officer  may
be   entitled  under  the  charter,  by-laws,  a  resolution   of
shareholders or directors, an agreement or otherwise.

     Under Section 13.1-697 of the Virginia Stock Corporation Act
("VSCA"),  a  Virginia corporation may indemnify a  Director  who
was, is, or is threatened to be made a party to any Proceeding if
the Director acted in good faith and (i) he believed, in the case
of  conduct  in his official capacity with the corporation,  that
his  conduct was in the best interests of the corporation or,  in
the  case  of  other conduct, that his conduct was at  least  not
opposed to the best interests of the corporation, or (ii) in  the
case  of  a  criminal proceeding, he had no reasonable  cause  to
believe  his  conduct  was  unlawful.   A  corporation  may   not
indemnify a Director in connection with (i) a Proceeding by or in
the  right  of  the corporation in which the Director  was  found
liable  to the corporation or (ii) any other proceeding  charging
improper personal benefit to him, whether or not involving action
in  his official capacity, in which he was adjudged liable on the
basis    that   personal   benefit   was   improperly   received.
Indemnification  permitted under this  section  of  the  VSCA  in
connection  with  a  Proceeding  by  or  in  the  right  of   the
corporation  is  limited  to  reasonable  expenses  incurred   in
connection with the Proceeding.

      Under  Section 13.1-698, unless limited by its Articles  of
Incorporation,  a  corporation must indemnify against  reasonable
expenses a Director who entirely prevails in the defense  of  any
Proceeding  to  which  he was a party because  he  is  or  was  a
Director of the corporation.  

                             II-2



       Under   Section   13.1-700.1,  a  court   of   appropriate
jurisdiction,  upon the application of a Director,  may  order  a
corporation   to  advance  or  reimburse  expenses   or   provide
indemnification if the court determines that the Director  is  so
entitled.  With respect to a Proceeding by or in the right of the
corporation, a court may order indemnification of the Director to
the extent of his reasonable expenses even though he was adjudged
liable to the corporation.

     Under Section 13.1-699, a corporation may advance reasonable
expenses to a Director made a party to a Proceeding under certain
circumstances, including the furnishing by the Director of (i)  a
written  statement of his good faith belief that he has  met  the
standard of conduct necessary to obtain indemnification and  (ii)
a  written  undertaking to repay the advance if it is  ultimately
determined  that  he did not meet that standard.   Under  Section
13.1-702,  a  corporation may indemnify an officer,  employee  or
agent  of a corporation to the same extent as a Director.   Under
Section  13.1-704,  a corporation may provide indemnification  in
addition  to  that  provided  by statute  if  authorized  by  its
Articles  of Incorporation, a bylaw made by the shareholders,  or
any    resolution    adopted   by   the   shareholders,    except
indemnification against willful misconduct or a knowing violation
of the criminal law.

      Pursuant  to Section 7.5 of the merger agreement  regarding
the  merger  of  Baltimore  Gas and Electric  Company  (BGE)  and
Potomac Electric Power Company (PEPCO) into the Corporation,  the
Corporation  will,  to  the  fullest  extent  not  prohibited  by
applicable  law, indemnify, defend and hold harmless the  present
and  former  directors, officers and employees  of  each  of  the
Corporation,   BGE,  PEPCO,  and  their  respective  subsidiaries
against (i) all losses, expenses (including reasonable attorneys'
fees   and   expenses),  claims,  damages,  costs,   liabilities,
judgments  or  amounts  that are paid  in  settlement  of  or  in
connection   with   any  claim,  action,  suit,   proceeding   or
investigation  (a) based in whole or in part  on  or  arising  in
whole  or  in part out of the fact that such person is or  was  a
director,  officer  or employee of such party or  any  subsidiary
thereof,  and (b) pertaining to any matter existing or  occurring
at  or prior to the effective time of the merger of BGE and PEPCO
into the Corporation (the "Effective Time"), whether asserted  or
claimed  prior to, at or after the Effective Time, and  (ii)  all
losses,  expenses  (including  reasonable  attorney's  fees   and
expenses),  claims,  damages, costs, liabilities,  judgments,  or
amounts that are paid in settlement of or in connection with  any
claim,  action, suit, proceeding or investigation based in  whole
or  in  part  on,  or  arising in whole or in  part  out  of,  or
pertaining   to   the  merger  agreement  or   the   transactions
contemplated thereby.

      Further,  the Corporation will for a period  of  six  years
after  the  Effective Time, cause to be maintained in effect  the
policies   of   directors'  and  officers'  liability   insurance
maintained  by  BGE and PEPCO; provided that the Corporation  may

                           II-3



substitute  therefor  policies of at  least  the   same  coverage
containing  terms that are no less advantageous with  respect  to
matters occurring prior to the Effective Time to the extent  such
liability insurance can be maintained annually at a cost  to  the
Corporation not greater than 200% of the current aggregate annual
premiums  for the policies currently maintained by BGE and  PEPCO
for their directors' and officers' liability insurance; provided,
further,  that  if  such insurance cannot  be  so  maintained  or
obtained at such cost, the Corporation will maintain or obtain as
much  of  such insurance for each of BGE and PEPCO as can  be  so
maintained  or obtained at a cost equal to 200% of the respective
current  annual  premiums  of each of BGE  and  PEPCO  for  their
directors' and officers' liability insurance.

Item 17.  Undertakings.

(a)  The undersigned Registrant hereby undertakes:
    
           (1)   To  file, during any period in which  offers  or
     sales  are  being made, a post-effective amendment  to  this
     Registration Statement:
     
               (i)  To include any prospectus required by Section
          10(a)(3) of the Securities Act of 1933;
     
                (ii)  To  reflect in the prospectus any facts  or
          events   arising  after  the  effective  date  of   the
          Registration  Statement  (or  the  most  recent   post-
          effective amendment thereof) which, individually or  in
          the  aggregate, represent a fundamental change  in  the
          information  set  forth in the Registration  Statement.
          Notwithstanding the foregoing, any increase or decrease
          in  volume  of securities offered (if the total  dollar
          value of securities offered would not exceed that which
          was  registered) and any deviation from the low or high
          end  of  the  estimated maximum offering range  may  be
          reflected  in  the form of prospectus  filed  with  the
          Commission   pursuant  to  Rule  424(b)  if,   in   the
          aggregate, the changes in volume and price represent no
          more  than  a  20%  change  in  the  maximum  aggregate
          offering  price  set  forth  in  the  "Calculation   of
          Registration  Fee" table in the effective  registration
          statement;
     
                (iii)  To  include any material information  with
          respect  to  the  plan of distribution  not  previously
          disclosed in the Registration Statement or any material
          change   to   such  information  in  the   Registration
          Statement;
     
                                  II-4




            Provided,  however,  that  paragraphs  (a)(1)(i)  and
     (a)(1)(ii) do not apply if the Registration Statement is  on
     Form S-3, Form S-8, or Form F-3 and the information required
     to  be  included  in  a post-effective  amendment  by  those
     paragraphs  is contained in periodic reports filed  with  or
     furnished to the Securities and Exchange Commission  by  the
     Registrant  pursuant to Section 13 or Section 15(d)  of  the
     Securities  Exchange  Act of 1934 that are  incorporated  by
     reference in the Registration Statement.

          (2)  That, for the purpose of determining any liability
     under  the  Securities Act of 1933, each such post-effective
     amendment shall be deemed to be a new Registration Statement
     relating to the securities offered therein, and the offering
     of  such securities at that time shall be deemed to  be  the
     initial bona fide offering thereof.

           (3)   To remove from registration by means of a  post-
     effective  amendment any of the securities being  registered
     which remain unsold at the termination of the offering.

(b)   The  undersigned  Registrant hereby  undertakes  that,  for
purposes of determining any liability under the Securities Act of
1933,  each filing of the Registrant's annual report pursuant  to
Section 13(a) or Section 15(d) of the Securities Exchange Act  of
1934  (and, where applicable, each filing of an employee  benefit
plan's  annual report pursuant to Section 15(d) of the Securities
Exchange  Act of 1934) that is incorporated by reference  in  the
Registration  Statement shall be deemed to be a  new Registration
Statement  relating to the  securities offered therein,  and  the
offering  of such securities at that time shall be deemed  to  be
the initial bona fide offering thereof.
