We make statements in this prospectus and the documents we incorporate by
reference that are considered forward-looking statements within the meaning of
the Securities Act of 1933 and the Securities Exchange Act of 1934. Sometimes
these statements will contain words such as "believes," "expects," "intends,"

future performance and are subject to risks, uncertainties and other important
factors that could cause our actual performance or achievements to be materially
different from those we project. These risks, uncertainties and factors include,
but are not limited to:

o       general economic, business and regulatory conditions;
o       energy supply and demand;
o       competition;
o       federal and state regulations;
o       availability, terms and use of capital;
o       nuclear and environmental issues;

o       operating our currently  regulated  generation assets in a deregulated
        market beginning July 1, 2000 without the benefit of a fuel rate
        adjustment clause;
o       loss of revenues due to customers choosing alternative suppliers;
o       higher volatility of earnings and cash flows;
o       increased financial requirements of our non-regulated subsidiaries;
o       inability to pass on to electric retail customers costs associated with
        providing them service during the electric rate freeze period; and
o       implications from the transfer of Baltimore Gas and Electric Company's
        generation assets to nonregulated subsidiaries of Constellation Energy.

Given these uncertainties, you should not place undue reliance on these
forward-looking statements. Please see the documents we incorporate by reference
for more information on these factors. These forward-looking statements
represent our estimates and assumptions only as of the date of this prospectus.

CONSTELLATION ENERGY

Constellation Energy became the holding company for Baltimore Gas and Electric
Company ("BGE") on April 30, 1999. Constellation Energy owns all the outstanding
shares of common stock of BGE and the subsidiaries formerly owned by BGE.

BGE is a public utility that has served Central Maryland for over 180 years. BGE
produces, purchases and sells electricity and purchases, transports and sells
natural gas. BGE also jointly owns and operates two electric generating plants
and one hydroelectric plant in Pennsylvania.

Constellation Energy owns the stock of several other companies primarily engaged
in diversified energy-services businesses. They are:

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

Constellation Energy also has two other subsidiaries:

o        Constellation Investments, Inc. - financial investments and;
o        Constellation Real Estate Group, Inc. - real estate and senior living.


CURRENT EVENTS
Electric Restructuring

On April 8, 1999, Maryland enacted legislation authorizing customer choice and
competition among electric suppliers. In addition, on November 10, 1999, the
Maryland Public Service Commission issued a restructuring order that resolved
the major issues surrounding electric restructuring. These matters are discussed
further in our 1999 Annual Report on Form 10-K. See Where You Can Find More
Information.

As a result of the deregulation of the electric generation owned by BGE , no
earlier than July 1, 2000, and upon receipt of all regulatory approvals, we
expect that BGE will transfer, at book value, its 1) nuclear generating assets,
2) nuclear decommissioning trust fund, 3) fossil generating assets and 4)
partial ownership interest in two coal plants and a hydroelectric plant located
in Pennsylvania, to our nonregulated subsidiaries. In total, these generating
assets represent about 6,240 megawatts of generation capacity with a total
projected net book value at June 30, 2000 of approximately $2.4 billion.

We expect BGE to transfer approximately $278 million of tax exempt debt to our
nonregulated subsidiaries related to the transferred assets and that BGE will
receive approximately $ 426 million in unsecured promissory notes. Repayments of
the notes by our nonregulated subsidiaries will be used exclusively to service
certain long-term debt of BGE. BGE will also transfer equity associated with the
generating assets to our nonregulated subsidiaries.
                                       4

<PAGE>

The fossil fuel and nuclear fuel inventories, materials and supplies, and
certain purchase power contracts of BGE will also be assumed by these entities.

Under the Restructuring Order, BGE will provide standard offer service to
customers at fixed rates over various time periods during the transition period
for those customers that do not choose an alternate supplier once customer
choice begins July 1, 2000. In addition, the electric fuel rate will be
discontinued effective July 1, 2000. Our nonregulated subsidiaries will provide
BGE with the energy and capacity required to meet its standard offer service
obligations for the first three years of the transition period. Standard offer
service will be competitively bid thereafter.

Our nonregulated subsidiaries will obtain the energy and capacity to supply
BGE's standard offer service obligations from our Calvert Cliffs Nuclear Power
Plant (Calvert Cliffs) and BGE's former fossil plants, supplemented with energy
purchased from the wholesale energy market as necessary. Our earnings will be
exposed to the risks of the competitive wholesale electricity market to the
extent that our nonregulated subsidiaries have to purchase energy and/or
capacity or generate energy to meet obligations to supply power to BGE at market
prices or costs, respectively, which may approach or exceed BGE's standard offer
service rates. We will also be affected by operational risk, that is, the risk
that a generating plant is not available to produce energy when the energy is
required.

Until July 1, 2000, we will continue to recover our cost of electric fuel as
long as the Maryland PSC finds that, among other things, we have kept the
productive capacity of our generating plants at a reasonable level. After July
1, 2000, any energy purchased to meet BGE's load commitments will become a cost
of doing business in the newly competitive marketplace. Therefore, if BGE
provides standard offer service at fixed rates to its customers that do not
select an alternative provider as required under the terms of the Restructuring
Order, and the load demand exceeds our capacity to supply energy due to a plant
outage, we would be required to purchase additional power in the wholesale
energy market. If the price of obtaining energy in the wholesale market exceeds
the fixed standard offer service price, our earnings would be adversely
affected. Imbalances in demand and supply can occur not only because of plant
outages, but also because of transmission constraints or due to extreme
temperatures (hot or cold) causing demand to exceed available supply.

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

Corporate Reorganization

In anticipation of the deregulation of Maryland's electric industry on July 1,
2000, we are realigning our organization. We are combining the existing power
marketing and trading functions of Constellation Power Source with the domestic
plant operations, development and generation functions of Constellation Power
and, on or about July 1, 2000, the electric generation portion of BGE's
business. Together these functions will form an integrated domestic merchant
energy organization that will strategically develop, own and operate power
plants, market and trade power, and manage risk in the wholesale energy market.

PRICING SUPPLEMENT

The pricing supplement, which may also be called a prospectus supplement, for
each offering of notes will contain the specific information and terms for that
offering. The pricing supplement may

                                       5

<PAGE>
also add, update or change information contained in this prospectus. It is
important for you to consider the information contained in this prospectus and
the pricing supplement in making your investment decision.

USE OF PROCEEDS

Based on our current plans and estimates the net proceeds from the sale of the
notes will be used for general corporate purposes relating to our
nonregulated businesses, including repayment of commercial paper borrowings used
to finance capital expenditures and operations. We may, however, use the net
proceeds for other purposes if we find it necessary. If we do not use the net
proceeds immediately, we temporarily invest them in short-term, interest-bearing
obligations.



 For current information on our commercial paper balances and average interest
rate, see our most recent Form 10-K and 10-Q. See Where You Can Find More
Information.

DESCRIPTION OF THE NOTES

General

We will issue the notes under an indenture between us and the trustee, The Bank
of New York, dated as of March 24, 1999. This prospectus briefly outlines some
of the indenture provisions. The indenture is a contract between us and The Bank
of New York acting as trustee. The trustee has two main roles. First, the
trustee can enforce your rights against us if an "Event of Default" described
below occurs. Second, the trustee performs certain administrative duties for us.

The indenture is summarized below. Because it is a summary, it does not contain
all of the information that may be important to you. We have filed the indenture
and its supplements with the SEC, and we suggest that you read those parts of
the indenture that are important to you. You especially need to read the
indenture to get a complete understanding of your rights and our obligations
under the provisions described in Event of Default; Consolidation, Merger or
Sale; and Modification of Indenture. See Where You Can Find More Information to
find out how to locate the indenture and the supplements. You may also review
the indenture at the trustee's offices at 101 Barclay Street, New York, New
York.

The specific terms of each offering of notes will be described in the particular
pricing supplement relating to that offering. The pricing supplement may or may
not modify the general terms found in this prospectus and will be filed with the
SEC. For a complete description of the terms of a particular offering of notes,
you should read both this prospectus and the pricing supplement relating to that
particular offering.

The indenture does not limit the amount of notes that may be issued. Each series
of notes may differ as to their terms. For current information on our debt
outstanding see our most recent Form 10-K and 10-Q. See Where You Can Find More
Information.

The notes are unsecured and will rank equally with all our unsecured
indebtedness. The notes will be denominated in U.S. dollars and we will pay
principal and interest in U.S. dollars. The notes will not be subject to any
conversion, amortization, or sinking fund. It is anticipated that the notes will
be "book-entry," represented by a permanent global note registered in the name
of The Depository Trust Company, or its nominee. However, we reserve the right
to issue notes in certificate form registered in the name of the noteholders.

In the discussion that follows, whenever we talk about paying principal on the
notes, we mean at maturity, redemption or repurchase. Also, in discussing the
time for notices and how the different interest rates are calculated, all times
are New York City time, unless otherwise noted.

The following terms may apply to each note as specified in the applicable
pricing supplement and the note. The applicable pricing supplement will describe
the terms for the notes including: interest rate, remarketing provisions, our
right to redeem notes, the holders' right to tender notes, and any other
provisions.

Redemptions

We may redeem notes at our option. Notes may be redeemable in whole or in part
in increments of $1,000 upon no more than 60, and not less than 30 days prior
notice. If we do not redeem all the notes of a series at one time, the Trustee
selects the notes to be redeemed in a manner it determines to be fair.

                                       8

<PAGE>

Repurchases

The noteholder may have the right to cause us to repurchase the notes. We will
repurchase the notes in whole or in part in increments of $1,000. The method for
repurchases differs for book-entry and certificate notes, and is discussed later
in this section, Description of the Notes.

Remarketed Notes

We may issue notes with remarketing features that allow holders the option to
sell their notes back to us. In turn, we have the option to retire these notes
or remarket and sell them to new holders.

Book-Entry Notes - Registration, Transfer, and Payment of Interest and Principal

Book-entry notes of a series will be issued in the form of a global note that
will be deposited with The Depository Trust Company, New York, New York ("DTC").
This means that we will not issue certificates to each holder. One global note
will be issued to DTC who will keep a computerized record of its participants
(for example, your broker) whose clients have purchased the notes. The
participant will then keep a record of its clients who purchased the notes.
Unless it is exchanged in whole or in part for a certificate note, a global note
may not be transferred; except that DTC, its nominees, and their successors may
transfer a global note as a whole to one another.

Beneficial interests in global notes will be shown on, and transfers of global
notes will be made only through, records maintained by DTC and its participants.

DTC has provided us the following information: DTC is a limited-purpose trust
company organized under the New York Banking Law, a "banking organization"
within the meaning of the New York Banking Law, a member of the United States
Federal Reserve System, a "clearing corporation" within the meaning of the New
York Uniform Commercial Code and a "clearing agency" registered under the
provisions of Section 17A of the Securities Exchange Act of 1934. DTC holds
securities that its participants ("Direct Participants") deposit with DTC. DTC
also records the settlement among Direct Participants of securities
transactions, such as transfers and pledges, in deposited securities through
computerized records for Direct Participant's accounts. This eliminates the need
to exchange certificates. Direct Participants include securities brokers and
dealers, banks, trust companies, clearing corporations and certain other
organizations.

DTC's book-entry system is also used by other organizations such as securities
brokers and dealers, banks and trust companies that work through a Direct
Participant. The rules that apply to DTC and its participants are on file with
the SEC.

DTC is owned by a number of its Direct Participants and by the New York Stock
Exchange, Inc., The American Stock Exchange, Inc.and the National Association of
Securities Dealers, Inc.

We will wire principal and interest payments to DTC's nominee. We and the
trustee will treat DTC's nominee as the owner of the global notes for all
purposes. Accordingly, we, the trustee and any paying agent will have no direct
responsibility or liability to pay amounts due on the global notes to owners of
beneficial interests in the global notes.

It is DTC's current practice, upon receipt of any payment of principal or
interest, to credit Direct Participants' accounts on the payment date according
to their respective holdings of beneficial interests in the global notes as
shown on DTC's records. In addition, it is DTC's current practice to assign any
consenting or voting rights to Direct Participants whose accounts are credited
with notes on a record date, by

                                       9
<PAGE>
using an omnibus proxy. Payments by participants to owners of beneficial
interests in the global notes, and voting by participants, will be governed by
the customary practices between the participants and owners of beneficial
interests, as is the case with notes held for the account of customers
registered in "street name." However, payments will be the responsibility of the
participants and not of DTC, the trustee or us.

Notes represented by a global note will be exchangeable for certificate notes
with the same terms in authorized denominations only if:

o    DTC notifies us that it is unwilling or unable to continue as depositary or
     if DTC ceases to be a clearing agency registered under applicable law and a
     successor depositary is not appointed by us within 90 days; or

o    We determine not to require all of the notes of a series to be represented
     by a global note and notify the trustee of our decision.

Book-Entry Notes - Method of Repurchase

Participants, on behalf of the owners of beneficial interests in the global
notes, may exercise the repurchase option by delivering written notice to our
paying agent at least 30, but no more than 60, days prior to the date of
repurchase. The paying agent, The Bank of New York, must receive notice by 5:00
p.m. on the last day for giving notice. Procedures for the owners of beneficial
interests in global notes to notify their participants of their desire to have
their note repurchased will be governed by the customary practices of the
participant. The written notice to the paying agent must state the principal
amount to be repurchased. It is irrevocable and a duly authorized officer of the
participant (with signatures guaranteed) must sign it.

Certificate Notes - Registration, Transfer, and Payment of Interest and
Principal

If we issue certificate notes, they will be registered in the name of the
noteholder. The notes may be transferred or exchanged, pursuant to
administrative procedures in the indenture, without the payment of any service
charge (other than any tax or other governmental charge) by contacting the
paying agent.

Holders of over $5 million in principal amount of notes can request that payment
of principal and interest be wired to them by contacting the paying agent at the
address set forth above at least one business day prior to the payment date.
Otherwise, payments will be made by check.

Certificate Notes - Method of Repurchase

Noteholders desiring to exercise their repurchase option must notify the paying
agent at least 30 but not more than 45 days prior to the repayment date by
providing the bank:

o    the note, with the section entitled "Option to Elect Repayment" on the
     reverse of the note completed; or
o    a fax or letter (first class, postage prepaid) from a member of a national
     securities exchange, the National Association of Securities Dealers, or a
     bank or trust company in the United States which states the following:

         the name of the holder;

         the principal amount of the note and the amount to be repurchased;

         the certificate number or the maturity and a description of the terms
         of the note;

         a statement that you wish to sell all or a portion of your note; and

                                       10

<PAGE>

o    A guaranty that the note with the section entitled "Option to Elect
     Repayment" on the reverse of the note completed, will be received by the
     paying agent within 5 business days.

The note and form must be received by the paying agent by such 5th business day.
Your notice of repurchase is irrevocable.

If you sell a portion of a note, the old note will be canceled and a new note
for the remaining principal amount will be issued to you.

Interest Rate

General

The interest rate on the notes will either be fixed or floating. The interest
paid will include interest accrued to, but excluding, the date of maturity,
redemption or repurchase. Interest is generally payable to the person in whose
name the note is registered at the close of business on the record date before
each interest payment date. Interest payable at maturity, redemption, or
repurchase, however, will be payable to the person to whom principal is payable.

The first interest payment on any note originally issued between a record date
and interest payment date or on an interest payment date will be made on the
interest payment date after the next record date. Interest payments, other than
those payable at maturity, redemption or repurchase will be paid, at our option,
by check or wire transfer.

Fixed Rate Notes

Each pricing supplement will designate the fixed rate of interest payable on a
note. Interest will be paid May 1 and November 1, and upon maturity, redemption
or repurchase. If any payment date falls on a day that is not a Business Day,
payment will be made on the next Business Day and no additional interest will be
paid. The record dates for such notes will be April 15 (for interest to be paid
on May 1) and October 15 (for interest to be paid on November 1). Interest
payments will be the amount of interest accrued to, but excluding, each May 1
and November 1. Interest will be computed using a 360-day year of twelve 30-day
months.

"Business Day" means any day other than a Saturday or Sunday that (a) is not a
day on which banking institutions in the state of Maryland, or in New York, New
York, are authorized or obligated by law or executive order to be closed, and
(b) with respect to floating rate notes with a LIBOR interest rate formula only,
is a day on which dealings in deposits in U.S. dollars are transacted in the
London interbank market.

Floating Rate Notes

General

Each floating rate note will have an interest rate formula. The formula may be
based on:

o        the commercial paper rate;
o        the prime rate;
o        the CD rate;
o        the federal funds effective rate;
o        the LIBOR;
o        the Treasury rate;
o        the CMT rate; or
o        another interest rate index.

The interest rate for each interest period will be based on the formula plus a
spread or multiplied by a spread multiplier, if any, as indicated in the
applicable pricing supplement. In addition, any floating rate note may have a
maximum or minimum interest rate limitation.

Date of Interest Rate Change

The interest rate on each floating rate note may be reset daily, weekly,
monthly, quarterly, semi-annually, or annually based

                                       11

<PAGE>
on the Index Maturity for the interest rate formula as specified in the
applicable pricing supplement.  "Index Maturity" means the period to maturity
on the referenced floating interest rate contract on which the interest rate
formula is based. The specific dates on which the interest rate will reset
(Interest Reset Date) will be specified in the applicable pricing supplement
and will be:

o       for notes which reset daily, each Business Day;
o       for notes (other than Treasury rate notes) which reset weekly, the
        Wednesday of each week;
o       for Treasury rate notes which reset weekly, the Tuesday of each
        week;
o       for notes which reset monthly, the third Wednesday of each month;
o       for notes which reset quarterly, the third Wednesday of March, June,
        September and December;
o       for notes which reset semi-annually, the third Wednesday of the two
        months of each year indicated in the applicable pricing supplement; and
o       for notes which reset annually, the third Wednesday of the month of each
        year indicated in the applicable pricing supplement.

The initial interest rate or interest rate formula on each note effective until
the first Interest Reset Date will be indicated in the applicable pricing
supplement. Thereafter, the interest rate will be the rate determined on the
next Interest Determination Date, as explained below. Each time a new interest
rate is determined, it will become effective on the subsequent Interest Reset
Date. If any Interest Reset Date is not a Business Day, then the Interest Reset
Date will be postponed to the next Business Day. However, in the case of a LIBOR
note, if the next Business Day is in the next calendar month, the Interest Reset
Date will be the immediately preceding Business Day.

When Interest Rate is Determined

The interest rate for all notes (except Treasury rate notes) will be the rate
determined on the second Business Day before the Interest Reset Date (Interest
Determination Date).

The Interest Determination Date for Treasury rate notes will be the day of the
week in which the Interest Reset Date falls on which Treasury bills would
normally be auctioned. Treasury bills are usually sold at auction on Monday of
each week, unless that day is a legal holiday, in which case the auction is
usually held on Tuesday. However, the auction may be held on the preceding
Friday. If an auction is held on the preceding Friday, that day will be the
Interest Determination Date pertaining to the Interest Reset Date occurring in
the next week. If an auction date falls on any Interest Reset Date then the
Interest Reset Date will instead be the first Business Day immediately following
the auction date.

The Bank of New York or its successor, the Calculation Agent, will calculate the
interest rate on the tenth day or if not a business day, the next business day,
after the related Interest Determination Date (Calculation Date) for all
floating rate notes except LIBOR notes. For LIBOR notes the Calculation Date
will be the Interest Determination Date.

Upon request, the Calculation Agent, will provide the current interest rate and,
if different, the interest rate which will become effective on the next Interest
Reset Date.

When Interest Is Paid

Interest is paid as follows:

o for notes which reset daily or weekly, on the third Wednesday of March, June,
September and December;

o for notes which reset monthly, on the third Wednesday of each month or on the
third Wednesday of March, June, September and December (as indicated in the
applicable pricing supplement);

                                       12

<PAGE>
o for notes which reset quarterly, on the third Wednesday of March, June,
September, and December;

o for notes which reset semi-annually, on the third Wednesday of the two months
specified in the applicable pricing supplement;

o for notes which reset annually, on the third Wednesday of the month specified
in the applicable pricing supplement; and

o at maturity, redemption or repurchase.

If interest is payable on a day which is not a Business Day, payment will be
postponed to the next Business Day. However, for LIBOR notes, if the next
Business Day is in the next calendar month, interest will be paid on the
preceding Business Day.

The record date will be 15 calendar days prior to each day interest is paid,
whether or not such day is a Business Day.

The interest payable will be the amount of interest accrued to, but excluding,
the interest payment date. However, for notes on which the interest resets daily
or weekly, the interest payable will include interest accrued to and including
the record date prior to the interest payment date. If the interest payment date
is also a day that principal is due, the interest payable will include interest
accrued to, but exclude, the date of maturity, redemption or repurchase.

The accrued interest for any period is calculated by multiplying the principal
amount of a note by an accrued interest factor. The accrued interest factor is
computed by adding the interest factor calculated for each day in the period to
the date for which accrued interest is being calculated. The interest factor
(expressed as a decimal rounded upwards if necessary, as described below) is
computed by dividing the interest rate (expressed as a decimal rounded upwards
if necessary) applicable to such date by 360, unless the notes are Treasury rate
notes or CMT rate notes in which case it will be divided by the actual number of
days in the year.

All percentages resulting from any calculation of floating rate notes will be
rounded, if necessary, to the nearest one-hundred thousandth of a percentage
point, with five one-millionths of a percentage point rounded upwards (e.g.,
9.876545% (or .09876545) being rounded to 9.87655% (or .0987655) and 9.876544%
(or .09876544) being rounded to 9.87654% (or .0987654)), and all dollar amounts
used in or resulting from such calculation will be rounded to the nearest cent
(with one-half cent being rounded upwards).

Commercial Paper Rate Notes

Each commercial paper rate note will bear interest at the rate (calculated with
reference to the Commercial Paper Rate and the spread and/or spread multiplier,
if any) specified on the commercial paper rate note and in the applicable
pricing supplement.

"Commercial Paper Rate" means, with respect to any Commercial Paper Interest
Determination Date, the Money Market Yield (calculated as described below) of
the rate on such date for commercial paper having the Index Maturity specified
in the applicable pricing supplement as published in H.15(519) under the heading
"Commercial Paper." "H.15(519)" means the weekly statistical release entitled
"Statistical Release H.15(519), Selected Interest Rates," or any successor
publication, published by the Board of Governors of the Federal Reserve System.

The "Money Market Yield" is the yield (expressed as a percentage rounded
upwards, if necessary, to the next higher one-hundred thousandth of a percentage
point) calculated in accordance with the following formula:

                                       13
<PAGE>

Money Market Yield =

      D X 360         X  100
- ----------------------
  360 - (D X M)

where "D" refers to the per annum rate for commercial paper quoted on a bank
discount basis and expressed as a decimal; and "M" refers to the actual number
of days in the period for which interest is being calculated.

The following procedures will occur if the rate cannot be set as described
above:

(a)     If that rate is not published in H.15(519) prior to 9:00 A.M. on the
        Calculation Date, then the Commercial Paper Rate will be the Money
        Market Yield of the rate on the Commercial Paper Interest Determination
        Date for commercial paper having the Index Maturity specified in the
        applicable pricing supplement as published in Composite Quotations under
        the heading "Commercial Paper."

"Composite Quotation" means the daily statistical release entitled "Composite
3:30 P.M. Quotations for U.S. Government Securities," or any successor
publication, published by The Federal Reserve Bank of New York.

(b) If the rate is not published or in Composite Quotations by 3:00 P.M. on the
Calculation Date, the Commercial Paper Rate for that Commercial Paper Interest
Determination Date will then be calculated by the Calculation Agent in the
following manner.

The Commercial Paper Rate will be calculated as the Money Market Yield of the
average for the offered rates, as of 11:00 A.M., on that date, of three leading
dealers of commercial paper in New York selected for commercial paper having the
applicable Index Maturity placed for an industrial issuer whose bond rating is
"AA," or the equivalent, from a nationally recognized rating agency.

(c) Finally, if fewer than three dealers are quoting as mentioned, the rate of
interest in effect for the applicable period will be the same as the rate of
interest in effect for the prior interest reset period.

Prime Rate Notes

Each prime rate note will bear interest at the rate (calculated with reference
to the Prime Rate and the spread and/or spread multiplier, if any) specified on
the prime rate note and in the applicable pricing supplement.

"Prime Rate" means, with respect to any Prime Rate Interest Determination Date,
the rate set forth on such date in H.15(519) under the heading "Bank Prime
Loan."

The following procedures will occur if the rate cannot be set as described
above:

(a) If that rate is not published in H.15(519) prior to 9:00 A.M. on the
Calculation Date, then the Prime Rate will be the average (rounded upwards, if
necessary, to the next higher one-hundred thousandth of a percentage point) of
the rates of interest publicly announced by each bank that appear on the Reuters
Screen USPRIMEONE Page as its prime rate or base lending rate as in effect for
that Prime Rate Interest Determination Date.

(b) If fewer than four, but more than one, rates appear on the Reuters Screen
USPRIMEONE Page or replacement page, the Prime Rate will be the average of the
prime rates (quoted on the basis of the actual number of days in the year
divided by a 360-day year) as of the close of business on the Prime Rate
Interest Determination Date by four major money center banks in New York
selected by the Calculation Agent.

(c) If fewer than two rates appear, the Prime Rate shall be determined on the
basis

                                       14
<PAGE>
of the rates furnished in New York by the appropriate number of substitute
banks or trust companies organized and doing business under the laws of the
United States, or any State thereof, having total equity capital of at least
$500 million and being subject to supervision or examination by a Federal or
State authority, as selected by the Calculation Agent.

(d) Finally, if the banks are not quoting as mentioned above, the rate of
interest in effect for the applicable period will be the same as the rate of
interest in effect for the prior interest reset period.

CD Rate Notes

Each CD rate note will bear interest at the rate (calculated with reference to
the CD Rate and the spread and/or spread multiplier, if any) specified on the CD
rate note and in the applicable pricing supplement.

"CD Rate" means, with respect to any CD Rate Interest Determination Date, the
rate on that date for negotiable certificates of deposit having the Index
Maturity specified in the applicable pricing supplement as published in
H.15(519) under the heading "CDs (Secondary Market)."

The following procedures will occur if the rate cannot be set as described
above:

(a) If that rate is not published in H.15(519) prior to 9:00 A.M. on the
Calculation Date, then the CD Rate will be the rate on that CD Rate Interest
Determination Date for negotiable certificates of deposit having the applicable
Index Maturity as published in Composite Quotations under the heading
"Certificates of Deposit."

(b) If that rate is not published in Composite Quotations by 3:00 P.M. on that
Calculation Date, the CD Rate for that CD Interest Determination Date shall be
calculated by the Calculation Agent as follows:

The CD Rate will be calculated as the average of the secondary market offered
rates, as of 10:00 A.M., of three leading nonbank dealers of negotiable U.S.
dollar certificates of deposit in New York selected by the Calculation Agent for
negotiable certificates of deposit of major United States money market banks
with a remaining maturity closest to the Index Maturity specified in the
applicable pricing supplement in a denomination of $5,000,000.

(c) Finally, if fewer than three dealers are quoting as mentioned, the rate of
interest in effect for the applicable period will be the same as the rate of
interest in effect for the prior interest reset period.

Federal Funds Effective Rate Notes

Each federal funds effective rate note will bear interest at the rate
(calculated with reference to the Federal Funds Effective Rate and the spread
and/or spread multiplier, if any) specified on the federal funds effective rate
note and in the applicable pricing supplement.

"Federal Funds Effective Rate" means, with respect to any Federal Funds
Effective Interest Determination Date, the rate on such date for Federal Funds
as published in H.15(519) prior to 11:00 A.M. under the heading "Federal Funds
(Effective)."

The following procedures will occur if the rate cannot be set as described
above:

(a) If that rate is not published in H.15(519) prior to 11:00 A.M. on the
Calculation Date, then the Federal Funds Effective Rate will be the rate on that
Federal Funds Effective Interest Determination Date as published in Composite
Quotations under the heading "Federal Funds/Effective Rate."

(b) If that rate is not published in Composite Quotations by 3:00 P.M. on the
Calculation Date, the Federal Funds Effective Rate for that Federal Funds

                                       15
<PAGE>
Effective Interest Determination Date will be calculated by the Calculation
Agent as follows: The Federal Funds Effective Rate will be the average of the
rates, as of 11:00 A.M. on that date, for the last transaction in overnight
Federal Funds arranged by three leading brokers of federal funds transaction in
New York selected by the Calculation Agent.

(c) Finally, if fewer than three brokers are quoting as mentioned above, the
rate of interest in effect for the applicable period will be the same as the
rate of interest in effect for the prior interest reset period.

LIBOR Notes

Each LIBOR note will bear interest at the rate (calculated with reference to
LIBOR and the spread and/or spread multiplier, if any) specified on the LIBOR
note and in the applicable pricing supplement.

LIBOR will be determined by the Calculation Agent as follows:

        (a) With respect to any LIBOR Interest Determination Date, LIBOR will be
determined by either:

        (1) the average of the offered rates for deposits of not less than
$1,000,000 in U.S. dollars having the Index Maturity specified in the applicable
pricing supplement, beginning on the second Business Day immediately after that
date, that appear on the Reuters Screen LIBO Page as of 11:00 A.M., London time,
on that date, if at least two offered rates appear on the Reuters Screen LIBO
Page; or

        (2) the rate for deposits in U.S. dollars having the Index Maturity
designated in the applicable pricing supplement, beginning on the second London
Business Day immediately after such date, that appears on the Telerate Page 3750
as of 11:00 A.M., London time, on that date.

If neither Reuters Screen LIBO Page nor Telerate Page 3750 is specified in the
applicable pricing supplement, LIBOR will be determined as if Telerate Page 3750
had been specified.

In the case where (1) above applies, if fewer than two offered rates appear on
the Reuters Screen LIBO Page, or, in the case where (2) above applies, if no
rate appears on the Telerate Page 3750, LIBOR for that date will be determined
as follows:

        (b) LIBOR will be determined based on the rates at approximately 11:00
A.M., London time, on that LIBOR Interest Determination Date at which deposits
of not less than $1,000,000 in U.S. dollars having the applicable Index Maturity
are offered to prime banks in the London interbank market by four major banks in
the London interbank market selected by the Calculation Agent that in the
Calculation Agent's judgment is representative for a single transaction in such
market at such time (a "Representative Amount"). The offered rates must begin on
the second Business Day immediately after that LIBOR Interest Determination
Date.

The Calculation Agent will request the principal London office of each such bank
to provide a quotation of its rate. If at least two such quotations are
provided, LIBOR for such date will be the average of such quotations.

(c) If fewer than two quotations are provided, LIBOR for that date will be the
average of the rates quoted at approximately 11:00 A.M., New York City time, on
such date by three major banks in New York, selected by the Calculation Agent.
The rates will be for loans in U.S. dollars to leading European banks having the
specified Index Maturity beginning on the second Business Day after that date
and in a Representative Amount.

(d) Finally, if fewer than three banks are quoting as mentioned, the rate of
interest in effect for the applicable period will be the

                                       16
<PAGE>

same as the rate of interest in effect for the prior interest reset period.

Treasury Rate Notes

Each Treasury rate note will bear interest at the rate (calculated with
reference to the Treasury Rate and the spread and/or spread multiplier, if any)
specified on the Treasury rate note and in the applicable pricing supplement.

"Treasury Rate" means, with respect to any Treasury Interest Determination Date,
the rate for the most recent auction of direct obligations of the United States
("Treasury bills") having the Index Maturity specified in the applicable pricing
supplement as published in H.15(519) under the heading "U.S. Government
Securities/Treasury Bills/Auction Average (Investment)."

The following procedures will occur if the rate cannot be set as described
above:

(a) If that rate is not published in H.15(519) by 9:00 A.M. on the applicable
Calculation Date, the rate will be the auction average rate (expressed as a bond
equivalent, on the basis of a year of 365 or 366 days, as applicable, and
applied on a daily basis) for such auction as otherwise announced by the United
States Department of the Treasury.

(b) If the results of the auction of Treasury bills having the applicable Index
Maturity are not published in H.15(519) by 9:00 A.M., or otherwise published or
reported as provided above by 3:00 P.M., on the Calculation Date, or if no
auction is held in a particular week, then the Treasury Rate shall be calculated
by the Calculation Agent as follows:

The rate will be calculated as a yield to maturity (expressed as a bond
equivalent, on the basis of a year of 365 or 366 days, as applicable, and
applied on a daily basis) of the average of the secondary market bid rates as of
approximately 3:30 P.M. on the Treasury Interest Determination Date, of three
leading primary United States government securities dealers in New York selected
by the Calculation Agent for the issue of Treasury bills with a remaining
maturity closest to the specified Index Maturity.

(c) Finally, if fewer than three dealers are quoting as mentioned, the rate of
interest in effect for the period will be the same as the rate of interest in
effect for the prior interest reset period.

CMT Rate Notes

Each CMT rate note will bear interest at the rate (calculated with reference to
the CMT Rate and the Spread or Spread Multiplier, if any) specified on such CMT
rate note and in the applicable pricing supplement.

"CMT Rate" means, with respect to any CMT Interest Determination Date, the rate
displayed on the Designated CMT Telerate Page under the caption "... Treasury
Constant Maturities. Federal Reserve Board Release H.15... Mondays Approximately
3:45 P.M.," under the column for the applicable Index Maturity designated in the
applicable pricing supplement for:

        (1) if the Designated CMT Telerate Page is 7055, the rate for the
            applicable CMT Interest Determination Date; or

        (2) if the Designated CMT Telerate Page is 7052, the week, or the month,
            as applicable, ended immediately preceding the week in which the
            CMT Interest Determination Date occurs.

The following procedures will occur if the rate cannot be set as described
above:

(a) If no page is specified in the applicable pricing supplement and on the face
of such CMT Rate Note, the Designated CMT Telerate Page shall be 7052, for the
most recent week. If such rate is no longer displayed on the relevant page, or
if it is not displayed by 3:00 P.M. on the related Calculation Date, then the
CMT Rate

                                       17
<PAGE>

will be the Treasury constant maturity rate for the applicable Index
Maturity as published in the relevant H.15 (519).

(b) If that rate is no longer published in H.15(519), or is not published by
3:00 P.M. on the related Calculation Date, then the CMT Rate for such CMT
Interest Determination Date will be the Treasury constant maturity rate for the
applicable Index Maturity (or other United States Treasury rate for such Index
Maturity for that CMT Interest Determination Date with respect to such Interest
Reset Date) as may then be published by either the Federal Reserve Board or the
United States Department of the Treasury that the Calculation Agent determines
to be comparable to the rate formerly displayed on the Designated CMT Telerate
Page and published in the relevant H.15(519).

(c)     If that information is not provided by 3:00 P.M. on the related
        Calculation Date, then the CMT Rate for that CMT Interest Determination
        Date will be calculated by the Calculation Agent as follows:

The rate will be calculated as a yield to maturity, based on the average of the
secondary market closing offer side prices as of approximately 3:30 P.M. on that
CMT Interest Determination Date reported, according to their written records, by
three leading primary United States government securities dealers (each, a
"Reference Dealer") in New York selected by the Calculation Agent. These dealers
will be selected from five such Reference Dealers.

The Calculation Agent will eliminate the highest quotation (or, in the event of
equality, one of the highest) and the lowest quotation (or, in the event of
equality, one of the lowest), for the most recently issued direct noncallable
fixed rate obligations of the United States ("Treasury Note") with an original
maturity of approximately the applicable Index Maturity and a remaining term to
maturity of not less than such Index Maturity minus one year.

If two Treasury Notes with an original maturity as described in the preceding
sentence have remaining terms to maturity equally close to the applicable Index
Maturity, the quotes for the Treasury Note with the shorter remaining term to
maturity will be used.

(d) If the Calculation Agent cannot obtain three such Treasury Note quotations,
the CMT Rate for that CMT Interest Determination Date will be calculated by the
Calculation Agent as follows:

The rate will be calculated as a yield to maturity based on the average of the
secondary market offer side prices as of approximately 3:30 P.M. on that CMT
Interest Determination Date of three Reference Dealers in New York selected by
the Calculation Agent using the same method described above, for Treasury Notes
with an original maturity of the number of years that is the next highest to the
applicable Index Maturity with a remaining term to maturity closest to such
Index Maturity and in an amount of at least $100 million.

If three or four (and not five) of the Reference Dealers are quoting as
described above, then the CMT Rate will be based on the average of the offer
prices obtained and neither the highest nor the lowest of such quotes will be
eliminated.

(e) Finally, if fewer than three Reference Dealers are quoting as mentioned, the
rate of interest in effect for the applicable period will be the same as the
rate of interest in effect for the prior interest reset period.

Event of Default

"Event of Default" means any of the following:

o        failure to pay the principal of (or premium, if any, on) any note of a
         series when due and payable;

                                       18
<PAGE>
o        failure to pay for 30 days any interest on any note of any series;

o        failure to perform any other requirements in the notes, or in the
         indenture in regard to such notes, for 60 days after notice; or

o        certain events of insolvency.

An Event of Default for a particular series of notes does not necessarily mean
that an Event of Default has occurred for any other series of notes issued under
the indenture. If an Event of Default shall have occurred and be continuing the
Trustee or the holders of at least 33% of the principal amount of the notes of
the series affected by an Event of Default may require us to repay the entire
principal of the notes of such series immediately. Subject to certain
conditions, this requirement may be rescinded by the holders of at least a
majority in aggregate principal amount of the notes of the series.

The Trustee must within 90 days after a default occurs, notify the holders of
the notes of the series of the default if we have not remedied it (default is
defined to include the events specified above without the grace periods or
notice). The Trustee may withhold notice to the holders of such notes of any
default (except in the payment of principal or interest) if it in good faith
considers such withholding in the interest of the holders. We are required to
file an annual certificate with the Trustee, signed by an officer, about any
default by us under any provisions of the indenture.

Subject to the provisions of the indenture relating to its duties in case of
default, the Trustee shall be under no obligation to exercise any of its rights
or powers under the indenture at the request, order or direction of any holders
unless such holders offer the Trustee reasonable indemnity. Subject to the
provisions for indemnification and certain other limitations, the holders of a
majority in principal amount of the notes of any series may direct the time,
method and place of conducting any proceedings for any remedy available to, or
exercising any trust or power conferred on, the Trustee with respect to such
notes.

Modification of Indenture

Under the indenture, our rights and obligations and the rights of the holders of
any notes may be changed. Any change requires the consent of the holders of not
less than 66 2/3% in aggregate principal amount of the outstanding notes of all
series to be affected, voting as one class. However, no changes to the terms of
payment of principal or interest, or reducing the percentage required for
changes, is effective against any holder without its consent.

Consolidation, Merger or Sale

We may not merge or consolidate with any corporation or sell substantially all
of our assets as an entirety unless:

o    we are the continuing corporation or the successor corporation expressly
     assumes the payment of principal, and premium, if any, and interest on the
     notes and the performance and observance of all the covenants and
     conditions of the indenture binding on us; and

o    we, or the successor corporation, are not immediately after the merger,
     consolidation, or sale in default in the performance of a covenant or
     condition in the indenture.

PLAN OF DISTRIBUTION

We may sell the notes (a) through agents; (b) through underwriters or dealers;
or (c) directly to one or more purchasers.

of their

                                       19

appointment under the terms of an agency agreement between the agents
and us.

For each note and in total, we have set out below the offering price, the
compensation we will pay the agents and the proceeds we will receive, before
deducting expenses of approximately $365,000, depending on the maturity of the
notes they sell.

The agents will not be obligated to make a market in the notes. We cannot
predict the amount of trading or liquidity of the notes.

By Underwriters

If underwriters are used in the sale, the notes will be acquired by the
underwriters for their own account. The underwriters may resell the notes in one
or more transactions, including negotiated transactions, at a fixed public
offering price or at varying prices determined at the time of sale. The
obligations of the underwriters to purchase the notes will be subject to certain
conditions. The underwriters will be obligated to purchase all the notes of the
series offered if any of the notes are purchased. Any initial public offering
price and any discounts or concessions allowed or re-allowed or paid to dealers
may be changed from time to time.

Direct Sales

We may also sell notes directly. In this case, no underwriters or agents would
be involved.

General Information

In connection with sales by an agent or an underwritten offering, the SEC rules
permit the underwriters or agents to engage in transactions that stabilize the
price of the notes. These transactions may include purchases for the purpose of
fixing or maintaining the price of the notes.

The underwriters or agents may create a short position in the notes in
connection with the offering. That means they sell a larger principal amount of
the notes than is shown on the cover page of the prospectus or the applicable
pricing supplement. If they create a short position, the underwriters or agents
may purchase notes in the open market to reduce the short position.

If the underwriters or agents purchase the notes to stabilize the price or to
reduce their short position, the price of the notes could be higher than it
might be if they had not made such purchases. The underwriters or agents make no
representation or prediction about any effect that the purchases may have on the
price of the notes. These transactions may be affected on the open market and
may be discontinued at any time.



Underwriters, dealers, and agents that participate in the distribution of the
notes may be underwriters as defined in the Securities Act of 1933 (the "Act"),
and any discounts or commissions received by them from us and any profit on the
resale of the notes by them may be treated as underwriting discounts and
commissions under the Act.

We may have agreements with the underwriters, dealers and agents to indemnify
them against certain civil liabilities, including liabilities under the Act, or
to contribute with respect to payments which the underwriters, dealers or agents
may be required to make.

Underwriters, dealers and agents may engage in transactions with, or perform
services for, us or our subsidiaries in the ordinary course of their businesses.

                                       20

the ordinary course of its businesses.

Item 15.  Indemnification of Directors and Officers.

         The following description of indemnification allowed under Maryland
statutory law is a summary rather than a complete description. Reference is made
to Section 2-418 of the Corporations and Associations Article of the Maryland
Annotated Code, which is incorporated herein by reference, and the following
summary is qualified in its entirety by such reference.

         By a Maryland statute, 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"). Such indemnification may be against
judgments, penalties, fines, settlements and reasonable expenses actually
incurred by him in connection with the Proceeding unless it is proven that (a)
the act or omission of the Director was material to the matter giving rise to
the Proceeding and (i) was committed in bad faith, or (ii) was the result of
active and deliberate dishonesty; or (b) the Director actually received an
improper personal benefit in money, property, or services; or (c) in the case of
any criminal proceeding, the Director had reasonable cause to believe his act or
omission was unlawful. However, the 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 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

                                      II-1
<PAGE>

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 by statute is
not 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.

         A corporation may purchase and maintain insurance on behalf of any
person who is or was a Director or officer, whether or not the corporation would
have the power to indemnify a Director or officer against liability under the
provision of this section of Maryland law. Further, a corporation may provide
similar protection, including a trust fund, letter of credit or surety bond, not
inconsistent with the statute.

         Article Eighth of the Company's Charter reads as follows:

         "(a)
     (i) The Corporation shall indemnify

                  (A) Its Directors and Officers, whether serving the
Corporation or at its request any other entity, to the full extent required or
permitted by the general laws of the State of Maryland, now or hereafter in
force, including the advance of expenses, under the procedures and to the full
extent permitted by law, and

                (B) other employees and agents, to such extent as shall be
authorized by the Board of Directors or the Corporation's by-laws and be
permitted by law.

         (ii) The foregoing rights of indemnification shall not be exclusive of
any other rights to which those seeking indemnification may be entitled.

    (iii) The Board of Directors may take such action as is necessary to carry
out these indemnification provisions and is expressly empowered to adopt,
approve and amend from time to time such by-laws, resolutions or contracts
implementing such provisions or such further indemnification arrangements as may
be permitted by law. No amendment of the Charter of the Corporation
                                      II-2

<PAGE>

or repeal of
any of its provisions shall limit or eliminate the right to indemnification
provided hereunder with respect to any act or omission occurring prior to such
amendment or repeal.

               (b) To the fullest extent permitted by Maryland statutory or
decisional law, as amended or interpreted, no Director or Officer of this
Corporation shall be personally liable to the Corporation or its stockholders
for money damages. No amendment of the Charter of the Corporation or repeal of
any of its provisions shall limit or eliminate the limitation on liability
provided to Directors and Officers hereunder with respect to any act or omission
occurring prior to such amendment or repeal."

         Article V of the Company's By-Laws reads as follows:

         "The Corporation shall indemnify all Directors, Officers and employees
         to the fullest extent permitted by the general laws of the State of
         Maryland and shall provide indemnification expenses in advance to the
         extent permitted thereby. The Corporation will follow the procedures
         required by applicable law in determining persons eligible for
         indemnification and in making indemnification payments and advances.

         The Indemnification and advance of expenses provided by the Charter and
         these by-laws shall not be deemed exclusive of any other rights to
         which a person seeking indemnification or advance of expenses may be
         entitled under any law (common or statutory), or any agreement, vote of
         stockholders or disinterested Directors or other provision that is
         consistent with law, both as to action in his or her official capacity
         and as to action in another capacity while holding office or while
         employed by or acting as agent for the Corporation, shall continue in
         respect of all events occurring while a person was a Director or
         Officer after such person has ceased to be a Director or Officer, and
         shall inure to the benefit of the estate, heirs, executors and
         administrators of such person. All rights to indemnification and
         advance of expenses under the Charter of the Corporation and hereunder
         shall be deemed to be a contract between the Corporation and each
         Director or Officer of the Corporation who serves or served in such
         capacity at any time while this by-law is in effect. Nothing herein
         shall prevent the amendment of this by-law, provided that no such
         amendment shall diminish the rights of any person hereunder with
         respect to events occurring or claims made before its adoption or as to
         claims made after its adoption in respect of events occurring before
         its adoption. Any repeal or modification of this by-law shall not in
         any way diminish any rights to indemnification or advance of expenses
         of such Director or Officer or the obligations of the Corporation
         arising hereunder with respect to events occurring, or claims made,
         while this by-law or any provision hereof is in force."

                                      II-3

         The Directors and officers of the Company are covered by insurance
indemnifying them against certain liabilities which might be incurred by them in
their capacities as such, including certain liabilities arising under the
Securities Act of 1933. The premium for this insurance is paid by the Company.

         Also, see indemnification provisions in the Form of Agency Agreement
and the Standard Purchase Provisions, both included in Exhibit 1(a) to this
Registration Statement.

Item 16.  Exhibits.

         Reference is made to the Exhibit Index filed as a part of this
Registration Statement.

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;

                  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
                                      II-4

<PAGE>

         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.

(c) Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to Directors, officers and controlling persons of the
Registrant pursuant to the provisions described under Item 15 above, or
otherwise, the Registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Act and is, therefore, unenforceable. In the event that a claim
for indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a Director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such Director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

Dear Sirs:

     1. Introduction.  Constellation  Energy Group, Inc., a Maryland corporation
(the  "Company"),  confirms its agreement with Lehman  Brothers  Inc.,  Goldman,
Sachs  &  Co.  and  Merrill   Lynch,   Pierce,   Fenner  &  Smith   Incorporated
(individually,  an "Agent" and  collectively,  the "Agents") with respect to the
issue and sale from time to time by the Company of up to $500,000,000  aggregate
principal  amount  of its  Medium-Term  Notes,  Series B  registered  under  the
registration statement referred to in Section 2(a) (the "Notes"). The Notes will
be issued  under an  indenture,  dated as of March 24,  1999 (the  "Indenture"),
between the Company and The Bank of New York (the "Trustee").

     The Notes shall have the maturity  ranges  (which shall be from nine months
to thirty years),  annual interest rates,  redemption provisions and other terms
set  forth  in  the  Prospectus  referred  to  in  Section  2(a)  as it  may  be
supplemented from time to time. The Notes will be issued,  and the terms thereof
established,  from time to time by the Company in accordance with the Indenture,
the Notes and the Procedures (as defined in Section 3(d) hereof).

     2.  Representations  and Warranties of the Company.  The Company represents
and  warrants  to, and agrees with, each Agent as follows:

<PAGE>
                                      -2-

              (a) A registration  statement on Form S-3 (No. 333-) covering $500
million  principal amount of the Notes,  including a prospectus,  has been filed
with the  Securities  and  Exchange  Commission  ("Commission")  and has  become
effective.  Such registration  statement  including (i) the prospectus  included
therein dated _______ 2000 (such prospectus including each document incorporated
by reference  therein,  as may be amended or supplemented  from time to time, is
hereinafter  called  the  "Prospectus")  and  (ii) all  documents  filed as part
thereof or incorporated by reference therein,  as may be amended or supplemented
from time to time, are  hereinafter  called the  "Registration  Statement."  Any
reference in this Agreement to amending or supplementing the Prospectus shall be
deemed to include  the filing of  materials  incorporated  by  reference  in the
Prospectus  after the Closing Date and any  reference  in this  Agreement to any
amendment or  supplement to the  Prospectus  shall be deemed to include any such
materials incorporated by reference in the Prospectus after the Closing Date.

              (b) The  Registration  Statement  conforms in all  respects to the
requirements  of the  Securities  Act of  1933,  as  amended  ("Act"),  and  the
pertinent published rules and regulations of the Commission  thereunder ("33 Act
Rules and  Regulations") and the Trust Indenture Act of 1939, as amended ("Trust
Indenture Act"), and does not include any untrue statement of a material fact or
omit to state any material  fact  required to be stated  therein or necessary to
make the statements therein not misleading, and on the Closing Date, and at each
of the times of (i) acceptance referred to in Section 6(a) hereof, (ii) delivery
referred to in Section 6(e) hereof and (iii) amendment or supplement referred to
in  Section  6(b)  hereof  (the  Closing  Date and each such time  being  herein
sometimes referred to as "Representation  Date"), the Registration Statement and
the Prospectus will conform in all respects to the  requirements of the Act, the
Trust  Indenture  Act and the 33 Act  Rules  and  Regulations  and  none of such
documents  will contain an untrue  statement of a material  fact or will omit to
state any material fact  required to be stated  therein or necessary to make the
statements  therein not misleading,  except that the foregoing does not apply to
statements  or  omissions  in  such  document  based  upon  written  information
furnished  to the  Company  by any  Agent  specifically  for  use  therein.  The
documents  incorporated  by  reference  in  the  Registration  Statement  or the
Prospectus  pursuant  to Item 12 of Form S-3 of the Act,  at the time  they were
filed  with  the  Commission,   complied  in  all  material  respects  with  the
requirements  of the  Securities  Exchange  Act of 1934,  as amended  ("Exchange
Act"), and the pertinent published rules and regulations  thereunder  ("Exchange
Act Rules and Regulations").  Any additional documents deemed to be incorporated
by reference in the Prospectus  will,  when they are filed with the  Commission,
comply in all material  respects with the  requirements  of the Exchange Act and
the Exchange Act Rules and Regulations and will not contain an untrue  statement
of a  material  fact or omit to state a  material  fact  required  to be  stated
therein  or  necessary  to  make  the  statements   therein,  in

<PAGE>
                                      -3-
light  of  the circumstances under which they were made, not misleading.

      3.   Appointment as Agent; Solicitations as Agent.
           --------------------------------------------

              (a) Subject to the terms and conditions stated herein, the Company
hereby appoints each of the Agents as an agent of the Company for the purpose of
soliciting or receiving offers to purchase the Notes from the Company by others.

              (b) On the basis of the representations  and warranties  contained
herein,  but subject to the terms and  conditions  herein set forth,  each Agent
agrees, as agent of the Company, to use all reasonable efforts when requested by
the  Company  to  solicit  offers  to  purchase  the  Notes  upon the  terms and
conditions  set  forth  in the  Prospectus,  as from  time to  time  amended  or
supplemented.

              Upon receipt of notice from the Company as contemplated by Section
4(b) hereof,  each Agent shall  suspend its  solicitation  of purchases of Notes
until such time as the Company  shall have  furnished  it with an  amendment  or
supplement to the Registration Statement or the Prospectus,  as the case may be,
contemplated  by  Section  4(b) and shall  have  advised  each  Agent  that such
solicitation may be resumed.

              The Company reserves the right, in its sole discretion, to suspend
solicitation  of offers to  purchase  the Notes  commencing  at any time for any
period of time or  permanently.  Upon  receipt of notice from the  Company,  the
Agents will use their best efforts promptly to suspend solicitation of offers to
purchase  Notes from the  Company,  but in no event later than one  business day
after  notice,  until such time as the  Company has advised the Agents that such
solicitation  may  be  resumed.  For  the  purpose  of the  foregoing  sentence,
"business  day" shall mean any day which is not a Saturday  or a Sunday or a day
on which banking  institutions in The City of New York and the State of Maryland
are authorized or required by law or executive order to be closed.

              The Agents are authorized to solicit offers to purchase Notes only
in fully  registered  form,  in minimum  denominations  of $1,000  and  integral
multiples of $1,000 in excess  thereof,  and at a purchase  price which,  unless
otherwise specified in a supplement to the Prospectus, shall be equal to 100% of
the  principal  amount  thereof.  Each Agent shall  communicate  to the Company,
orally or in writing,  each reasonable offer to purchase Notes received by it as
Agent.  The Company  shall have the sole right to accept  offers to purchase the
Notes and may reject any such offer,  in whole or in part. Each Agent shall have
the  right,  in its  discretion  reasonably  exercised,  without  notice  to the
Company,  to reject any offer to purchase  Notes  received by it, in whole or in
part,  and any such  rejection  shall not be  deemed a breach  of its  agreement
contained herein.

<PAGE>
                                      -4-
              No Note  which the  Company  has agreed to sell  pursuant  to this
Agreement  shall be deemed to have been  purchased and paid for, or sold, by the
Company  until such Note  shall have been  delivered  to the  purchaser  thereof
against payment by such purchaser.

              (c) At the time of delivery of, and payment for, any Notes sold by
the Company as a result of a solicitation made by, or offer to purchase received
by, an Agent,  the Company  agrees to pay such Agent a commission  in accordance
with the schedule set forth in Exhibit A hereto.

              (d)  Administrative  procedures  respecting the sale of Notes (the
"Procedures")  shall be  agreed  upon from  time to time by the  Agents  and the
Company. The initial Procedures,  which are set forth in Exhibit B hereto, shall
remain in effect until  changed by  agreement  among the Company and the Agents.
Each  Agent  and  the  Company  agree  to  perform  the  respective  duties  and
obligations  specifically provided to be performed by each of them herein and in
the  Procedures.  The Company will furnish a copy of the Procedures as from time
to time in effect to the Trustee which will act as the authenticating  agent and
the agent  for  payment,  registration  and  notice  with  respect  to the Notes
pursuant to the  Indenture  and the agent for  calculating  interest  rates with
respect to floating  rate notes  pursuant  to the  Interest  Calculation  Agency
Agreement dated as of May 3, 1999 (the "Interest Calculation Agency Agreement").

              (e) The  documents  required to be  delivered  by Section 5 hereof
shall be  delivered  at the offices of the  Company,250  W. Pratt  Street,  20th
Floor, Baltimore,  Maryland, 21201, not later than 5:00 P.M., Baltimore time, on
the date of this  Agreement  or at such later time as may be mutually  agreed by
the Company  and the  Agents,  which in no event shall be later than the time at
which the Agents  commence  solicitation of purchases of Notes  hereunder,  such
time and date being herein called the "Closing Date."

      4. Certain  Agreements of the Company.  The Company agrees with the Agents
that it will  furnish to Cahill  Gordon & Reindel,  counsel for the Agents,  one
signed  copy of the  Registration  Statement,  including  all  exhibits  and all
documents incorporated by reference,  in the form it became effective and of all
amendments  thereto and that, in connection with each offering of Notes, it will
take the following actions:

(a) From the time solicitation regarding sale of the Notes is begun until all of
the Notes have been sold (i) the Company will advise each Agent  promptly of any
proposal to amend or supplement the Registration  Statement or the Prospectus by
means  of  a   post-effective   amendment,   sticker,   or  supplement   (except
post-effective amendment,  supplements, and stickers relating solely to interest
rates or maturities of Notes) but not by means of  incorporation  of document(s)
by reference into the Registration Statement or the Prospectus; (ii) the Company
will afford the

<PAGE>
                                      -5-
     Agents  a  reasonable   opportunity   to  comment  on  any  such   proposed
post-effective amendment,  sticker, or supplement; (iii) the Company will advise
each  Agent of the  filing of any such  post-effective  amendment,  sticker,  or
supplement;  and (iv) the Company will (x) advise each Agent of the  institution
by the Commission of any stop order  proceedings in respect of the  Registration
Statement  or of any part  thereof,  (y) use its best  efforts  to  prevent  the
issuance  of any such stop order,  and (z) if a stop order is issued,  to obtain
its lifting as soon as possible.

              (b) If from the time  solicitation  regarding sale of the Notes is
begun until all of the Notes have been sold, the Company shall determine that it
is necessary to suspend  solicitation  of the Notes because of the occurrence of
an event that results in the Prospectus either (x) including an untrue statement
of a material fact or omitting to state any material fact  necessary to make the
statements in such Prospectus,  in light of the  circumstances  under which they
were made when such Prospectus was delivered, not misleading,  or (y) failing to
comply with the Act, then the Company will promptly notify each Agent to suspend
solicitation  of  purchases  of the Notes.  Notwithstanding  Section 4(a) if the
Company shall  determine to amend or supplement  the  Registration  Statement or
Prospectus to correct such result, it will advise each Agent promptly and afford
the Agents a  reasonable  opportunity  to discuss and comment upon the nature of
the disclosure in such amendment or supplement.  Notwithstanding  the foregoing,
if at the time of any notification to suspend  solicitations  (i) this Agreement
shall be in effect and any Agent  shall own any of the Notes with the  intention
of reselling  them, or (ii) the Company has accepted an offer to purchase  Notes
but the related  settlement has not occurred,  then the Company,  subject to the
provisions of Section 4(a) of this  Agreement,  will  promptly  prepare and file
with the Commission an amendment or supplement which will correct such statement
or omission or effect such compliance.

              (c) The Company,  during the period when a prospectus  relating to
the Notes is required to be delivered  under the Act, will furnish to each Agent
promptly after timely filing with the  Commission  all documents  required to be
filed pursuant to Sections 13(a), 13(c), 14 or 15(d) of the Exchange Act (except
those  filings  associated  with  employee  benefit  plans).  The  Company  will
immediately  notify each Agent of any  downgrading in the rating of the Notes or
any other debt  securities  of the Company,  or any  proposal to  downgrade  the
rating  of the  Notes  or any  other  debt  securities  of the  Company,  by any
"nationally recognized statistical rating organization" (as defined for purposes
of Rule 436(g) under the Act), as soon as the Company learns of such downgrading
or proposal to downgrade.

              (d)  The  Company  will  furnish  to  each  Agent  copies  of  the
Registration  Statement,  including all exhibits  except those  incorporated  by
reference,   any  related  preliminary   prospectus,   any  related  preliminary
prospectus supplement, the Prospectus and all amendments and supplements to such
documents,  in each  case as soon as

<PAGE>
                                      -6-
available  and in such  quantities  as are reasonably requested.

              (e)  The  Company   will  use  its  best  efforts  to  obtain  the
qualification of the Notes for sale and the  determination of their  eligibility
for investment under the laws of such  jurisdictions as the Agents designate and
will  continue  such  qualifications  in  effect  so  long as  required  for the
distribution;  provided,  however,  that the  Company  shall not be  required to
qualify as a foreign  corporation  or to file any  consent to service of process
under  the laws of any  jurisdiction  or to comply  with any other  requirements
deemed by the Company to be unduly burdensome.

              (f) So long as any Notes are outstanding, the Company will furnish
to the Agents:  (i) as soon as practicable  after the end of each fiscal year, a
copy of its  annual  report  to  shareholders  for  such  year,  (ii) as soon as
available,  a copy of each report or definitive  proxy  statement of the Company
filed with the Commission under the Exchange Act or mailed to shareholders,  and
(iii) from time to time,  such other  information  concerning the Company as you
may reasonably request.

              (g) The Company will pay all expenses  incident to the performance
of its obligations  under this Agreement,  and will reimburse each Agent for any
expenses (including Blue Sky fees and disbursements of counsel which will not in
the aggregate exceed $6,000) incurred by it in connection with  qualification of
the Notes for sale and  determination of their  eligibility for investment under
the laws of such  jurisdictions  as such Agent may designate and the printing of
memoranda  relating  thereto,  for any filing fees charged by investment  rating
agencies  for the  rating  of the  Notes,  for any  filing  fee of the  National
Association  of  Securities  Dealers,  Inc.  relating to the Notes,  and for the
reasonable fees and disbursements of counsel to the Agents.

              (h) Not later  than 45 days after the end of the  12-month  period
beginning  at the end of any fiscal  quarter of the Company in which the Closing
Date or any other  Representation  Date occurs,  the Company will make generally
available  to its  security  holders an  earnings  statement  (which need not be
audited)  covering  such  12-month  period which will satisfy the  provisions of
Section 11(a) of the Act.

      5. Conditions of Obligations of Agents. The obligation of each Agent under
this Agreement at any time to solicit offers to purchase the Notes is subject to
the accuracy of the  representations and warranties of the Company herein on the
date  hereof,  on  each  Representation  Date  and  on the  date  of  each  such
solicitation,  to the accuracy of the statements of the Company's  officers made
pursuant to the provisions  hereof on each such date, to the  performance by the
Company of its obligations  hereunder on or prior to each such date, and to each
of the following additional conditions precedent:

<PAGE>
                                      -7-
              (a) No stop order suspending the effectiveness of the Registration
Statement or of any part thereof shall have been issued and no  proceedings  for
that purpose shall have been  instituted  or, to the knowledge of the Company or
any Agent, shall be contemplated by the Commission.

              (b) Neither the  Registration  Statement  nor the  Prospectus,  as
amended  or  supplemented  as  of  any  Representation  Date  or  date  of  such
solicitation,  as the case may be,  shall  contain any untrue  statement of fact
which,  in the opinion of any Agent, is material or omits to state a fact which,
in the opinion of such Agent,  is material and is required to be stated  therein
or is necessary to make the statements therein not misleading.

              (c) There shall not have occurred (i) any suspension or limitation
of trading in securities  generally on the New York Stock  Exchange other than a
temporary suspension in trading to provide for an orderly market, or any setting
of minimum prices for trading on such exchange,  or any suspension of trading of
any securities of the Company on any exchange or in the over-the-counter market;
(ii) any  banking  moratorium  declared by Federal or New York  authorities;  or
(iii) any outbreak or escalation of major hostilities in which the United States
is  involved,  any  declaration  of war by  Congress  or any  other  substantial
national or international  calamity or emergency if, in the reasonable  judgment
of such  Agents,  the  effect  of any such  outbreak,  escalation,  declaration,
calamity or  emergency  makes it  impractical  or  inadvisable  to proceed  with
solicitations of purchases of, or sales of, Notes.

              (d) At the  Closing  Date,  the  Agents  shall  have  received  an
opinion,  dated the Closing  Date,  of a counsel for the Company,  to the effect
that:

                     (i) The Company,  Baltimore Gas and Electric  Company (BGE)
              and   Constellation   Enterprises,   Inc.  (CEI)  have  been  duly
              incorporated  and are  validly  existing as  corporations  in good
              standing  under the laws of the State of Maryland,  with power and
              authority (corporate and other) to own their respective properties
              and  conduct  their  respective  businesses  as  described  in the
              Prospectus;  the  Company  owns all of the  outstanding  shares of
              common stock of BGE and CEI; and the Company is duly  qualified to
              do  business  as a foreign  corporation  in good  standing  in all
              jurisdictions  in  which  the  conduct  of  its  business  or  the
              ownership of its properties  requires such  qualification  and the
              failure to do so would have a material  and adverse  impact on its
              financial condition;

                     (ii) The Indenture has been duly  authorized,  executed and
              delivered  by the  Company,  and is a  valid  instrument,  legally
              binding on the Company,  enforceable in accordance with its terms,
              except  as  limited  by  bankruptcy,  insolvency,  or  other  laws
              affecting  the  enforcement  of  creditors'  rights and by general
              principles of equity;

<PAGE>
                                      -8-

                     (iii)  The  issuance  and  sale of  Notes  have  been  duly
              authorized by all necessary  corporate action of the Company.  The
              Notes  (assuming  that they have  been duly  authenticated  by the
              Trustee  or a  duly  designated  Authentication  Agent  under  the
              Indenture,  which fact counsel need not verify by an inspection of
              the Notes),  when issued in accordance with the provisions of this
              Agreement and the  Indenture,  will be duly issued and  constitute
              legal, valid and binding obligations of the Company enforceable in
              accordance  with  their  terms and are  entitled  to the  benefits
              provided  by the  Indenture,  except  as  limited  by  bankruptcy,
              insolvency or other laws  affecting the  enforcement of creditors'
              rights and by general principles of equity;

                     (iv) The Registration  Statement has become effective under
              the Act and (a) to the best of such counsel's  knowledge,  no stop
              order suspending the  effectiveness of the Registration  Statement
              has been  issued and no  proceedings  for that  purpose  have been
              instituted or are pending or  contemplated  under the Act; (b) the
              Registration   Statement  (as  of  its  effective  date)  and  the
              Prospectus  (as of the Closing Date) appeared to comply as to form
              in all material  respects with the  requirements of Form S-3 under
              the  Act and  the 33 Act  Rules  and  Regulations  and  the  Trust
              Indenture  Act;  (c) such  counsel  has no reason to believe  that
              either the Registration  Statement as of its effective date or the
              Prospectus as of the date of this  Agreement  contained any untrue
              statement of a material fact or omitted to state any material fact
              required to be stated  therein or necessary to make the statements
              therein not misleading;  (d) the  descriptions in the Registration
              Statement  and  Prospectus  of  statutes,  legal and  governmental
              proceedings  and  contracts  and other  documents are accurate and
              fairly present the information  required to be shown; and (e) such
              counsel  does not know of any  legal or  governmental  proceedings
              required to be described in the Prospectus which are not described
              as  required,  nor of any  contracts  or  documents of a character
              required  to  be  described  in  the  Registration   Statement  or
              Prospectus  or  to  be  filed  as  exhibits  to  the  Registration
              Statement  which are not described or filed as required;  it being
              understood that such counsel, in addressing the matters covered in
              this paragraph  (iv),  need express no opinion as to the financial
              statements  or  other   financial  and   statistical   information
              contained  in the  Registration  Statement  or the  Prospectus  or
              incorporated  therein or attached  as an exhibit  thereto or as to
              the Statement of Eligibility and  Qualification on Form T-1 of the
              Trustee under the Indenture;

                     (v)  Counsel  knows  of  no  approval  of  any   regulatory
              authority  which  is  legally  required  for the  valid  offering,
              issuance, sale and delivery of the Notes by the

                                      -9-

             Company under this  Agreement  (except that such opinion need not
             pass upon the requirements of state securities acts);

                     (vi) To the best of such  counsel's  knowledge  and belief,
              the  consummation  of  the   transactions   contemplated  in  this
              Agreement and the  compliance by the Company with all the terms of
              the  Indenture  did not and will not  result in a breach of any of
              the terms or  provisions  of, or constitute a default  under,  the
              Company's Charter or By-Laws or any indenture, mortgage or deed of
              trust or other  agreement or  instrument to which the Company is a
              party;

                     (vii) Each of this  Agreement and the Interest  Calculation
              Agency Agreement has been duly authorized,  executed and delivered
              by the Company;

                     (viii) The Indenture is duly qualified under the Trust
             Indenture Act;

                     (ix)  The  issuance,  sale  and  delivery  of the  Notes as
              contemplated  by this Agreement are not subject to the approval of
              the Commission  under the provisions of the Public Utility Holding
              Company Act of 1935, as amended (the "1935 Act"); and

                     (x) The Notes and  Indenture  conform  as to legal  matters
              with the statements concerning them in the Registration  Statement
              and Prospectus under the caption "DESCRIPTION OF NOTES" and on the
              cover page of the Prospectus.

              (e)  At the  Closing  Date,  the  Agents  shall  have  received  a
certificate,  dated the Closing Date, of the Chairman of the Board, President or
any Vice  President  and a  principal  financial  or  accounting  officer of the
Company in which such officers,  to the best of their knowledge after reasonable

are involved,  shall state that (i) the  representations  and  warranties of the
Company in this  Agreement are true and correct in all material  respects,  (ii)
the Company has complied with all agreements and satisfied all conditions on its
part to be  performed or  satisfied  hereunder at or prior to the Closing  Date,
(iii) no stop order suspending the  effectiveness of the Registration  Statement
or of any part thereof has been issued and no proceedings  for that purpose have
been instituted or are  contemplated  by the Commission,  and (iv) subsequent to
the date of the most recent  financial  statements set forth or  incorporated by
reference in the  Prospectus,  there has been no material  adverse change in the
financial  position or in the  financial  results of  operations of the Company,

confirming that they are independent pubic  accountants  within the meaning
of the Act and the 33 Act Rules and Regulations, and stating in effect that:

                     (i) In their opinion, the consolidated financial statements
              and supporting schedules audited by them which are included in the
              Company's  Form  10-K  ("Form  10-K"),  which is  incorporated  by
              reference  in the  Registration  Statement  comply  in form in all
              material respects with the applicable  accounting  requirements of
              the Act and the 33 Act Rules and  Regulations and the Exchange Act
              and the Exchange Act Rules and Regulations;

                     (ii) On the basis of  procedures  specified  in such letter
              (but not an audit in accordance with generally  accepted  auditing
              standards),  including  reading  the  minutes of  meetings  of the
              shareholders,  the Board of Directors and the Executive  Committee
              of the Company  since the end of the year covered by the Form 10-K
              as set forth in the minute books through a specified date not more
              than  five  days  prior  to  the  Closing  Date,   performing  the
              procedures  specified in Statement on Auditing  Standards  No. 71,
              Interim   Financial   Information,   on  the   unaudited   interim
              consolidated  financial  statements of the Company incorporated by
              reference in the Registration  Statement,  if any, and reading the
              latest  available   unaudited   interim   consolidated   financial
              statements  of  the  Company,  and  making  inquiries  of  certain
              officials of the Company who have responsibility for financial and
              accounting  matters as to whether the latest  available  financial
              statements  not  incorporated  by  reference  in the  Registration
              Statement are prepared on a basis  substantially  consistent  with
              that of the audited consolidated financial statements incorporated
              in the Registration Statement, nothing has come to their attention
              that  has  caused   them  to  believe   that  (1)  any   unaudited
              consolidated financial statements incorporated by reference in the
              Registration  Statement  do not  comply  in form  in all  material
              respects with the  applicable  requirements  of the Act and the 33
              Act Rules and  Regulations  and the  Exchange Act and the Exchange
              Act Rules and Regulations or any material  modifications should be
              made to those unaudited consolidated financial statements for them
              to be in conformity with generally accepted accounting principles;
              (2)  at the  date  of  the  latest  available  balance  sheet  not
              incorporated by reference in the Registration  Statement there was
              any  change in the  capital  stock,  change in  long-term  debt or
              decrease in consolidated net assets or common shareholders' equity
              as compared  with the amounts  shown in the latest  balance  sheet
              incorporated by reference in the Registration Statement or for the
              period  from  the  closing  date of the  latest  income  statement
              incorporated  by  reference in the  Registration  Statement to the
              closing date of the latest available income statement read by them
              there  were any  decreases,  as  compared  with the

<PAGE>
                                      -11-

        corresponding period of the previous year, in operating revenues,
        operating income, net income, the ratio of earnings to fixed charges
        (measured on the most recent twelve month period),  or in earnings per
        share of common stock except in all instances of changes or decreases
        that the Registration  Statement discloses have occurred or may occur,
        or which are described in such letter;  or (3) at a specified date not
        more than five days prior to the Closing Date,  there was any change in
        the capital stock or long-term  debt of the Company or, [at such date,
        there was any  decrease in net assets of the Company as  compared  with
        amounts shown in the latest balance sheet  incorporated by reference in
        the Registration Statement],  [or for the  period  from the  closing
        date of the  latest  income statement incorporated by reference in the
        Registration Statement to a specified date not more than five days prior
        to the Closing Date, there were any decreases as compared  with the
        corresponding  period of the previous  year, in operating revenues,
        operating  income,  net income or in  earnings  applicable  to common
        stock,]  except in all cases for  instances  of  changes or  decreases
        that the Registration  Statement  discloses  have  occurred  or may
        occur,  or which are described in such letter; and

                (iii)  Certain  specified  procedures  have been applied to
              certain financial or other statistical  information (to the extent
              such information was obtained from the general  accounting records
              of the  Company)  set forth or  incorporated  by  reference in the
              Registration  Statement and that such procedures have not revealed
              any disagreement between the financial and statistical information
              so set forth or incorporated and the underlying general accounting
              records of the Company, except as described in such letter.

              (g) The Agents shall have  received  from Cahill Gordon & Reindel,
counsel for the Agents,  an opinion dated the Closing Date,  with respect to the
matters referred to in paragraph 5(d) subheadings (ii), (iii), (iv)b,  (v),(vii)
(viii),  and (x) and such  other  related  matters  as you may  require  and the
Company shall have  furnished to such counsel such documents as they request for
the purpose of enabling them to pass on such matters.

              In rendering such opinion, Cahill Gordon & Reindel may rely, as to
the incorporation of the Company,  and all other matters governed by the laws of
the State of Maryland,  and the  applicability of the 1935 Act for the issuance,
sale and  delivery  of the Notes upon the  opinion of  Counsel  for the  Company
referred to above.

              In  addition,  such  counsel  shall  state that such  counsel  has
participated in conferences with officers,  counsel and other representatives of
the Company, representatives of the independent certified public accountants for
the  Company  and  representatives  of the Agents at which the  contents  of the

<PAGE>
                                      -12-

Registration  Statement and the Prospectus and related  matters were  discussed;
and,   although   such   counsel  is  not  passing  upon  and  does  not  assume
responsibility  for the  accuracy,  completeness  or fairness of the  statements
contained in the Registration Statement and Prospectus (except as to the matters
referred to in their opinion rendered  pursuant to subheading (x) above), on the
basis of the  foregoing  (relying as to  materiality  to a large extent upon the
opinions of officers,  counsel and other  representatives  of the  Company),  no
facts have come to the  attention  of such  counsel  which lead such  counsel to
believe that either the Registration Statement (as of its effective date) or the
Prospectus (as of the date of this Agreement),  contained an untrue statement of
a  material  fact or  omitted to state a  material  fact  required  to be stated
therein or necessary to make such  statements  therein not  misleading (it being
understood  that such counsel need make no comment with respect to the financial
statements  and other  financial  and  statistical  information  included in the
Registration  Statement  or  Prospectus  or  incorporated  therein  or as to the
Statement of Eligibility and  Qualification on Form T-l of the Trustee under the
Indenture).

              The Company will furnish the Agents with such conformed  copies of
such  opinions,  certificates,  letters and  documents as the Agents  reasonably
request.

      6.   Additional Covenants of the Company.  The Company agrees that:
           -----------------------------------

              (a) Each acceptance by the Company of an offer for the purchase of
Notes  shall  be  deemed  to be an  affirmation  that  its  representations  and
warranties  contained in this Agreement are true and correct at the time of such
acceptance,  it being understood that such  representations and warranties shall
relate  to  the  Registration   Statement  and  the  Prospectus  as  amended  or
supplemented  at each such time. Each such acceptance by the Company of an offer
for  the  purchase  of  Notes  shall  be  deemed  to  constitute  an  additional
representation, warranty and agreement by the Company that, as of the settlement
date for the sale of such Notes,  after  giving  effect to the  issuance of such
Notes and of any other Notes to be issued on or prior to such  settlement  date,
the  aggregate  amount of Notes  which have been  issued and sold by the Company
will not exceed  the amount of Notes  registered  pursuant  to the  Registration
Statement.

              (b) From the time solicitation  regarding the sale of the Notes is
begun until all of the Notes have been sold, each time the Company (i) amends or
supplements  the  Registration  Statement  or  the  Prospectus  (other  than  in
reference  solely  to  interest  rates or  maturities  of  Notes)  by means of a
post-effective   amendment,   sticker,   or  supplement  but  not  by  means  of
incorporation of document(s) by reference into the Registration Statement or the
Prospectus;  (ii) files an annual  report on Form 10-K under the  Exchange  Act;
(iii) files its quarterly  reports on Form 10-Q under the Exchange Act; and (iv)
files a report on Form

<PAGE>
                                      -13-

     8-K under the Exchange  Act (the date of filing each of the  aforementioned
documents is referred to as a "Representation  Date"); the Company shall furnish
the Agents (but in the case of (iv) above only if  requested by the Agents) with
a certificate  of the Chairman,  President or any Vice President and a principal
financial or  accounting  officer of the Company,  in form  satisfactory  to the
Agents,  to the effect  that on the  Representation  Date,  to the best of their
knowledge after reasonable investigation and relying upon opinions of counsel to
the extent legal matters are involved, (i) the representations and warranties of
the Company in this  Agreement  are true and correct in all  material  respects;
(ii) the Company has complied with all  agreements  and satisfied all conditions
on  its  part  to be  performed  or  satisfied  hereunder  at or  prior  to  the
Representation  Date;  (iii) no stop order  suspending the  effectiveness of the
Registration Statement or of any part thereof has been issued and no proceedings
for that purpose have been instituted or are contemplated by the Commission; and
(iv) subsequent to the date of the most recent financial statements set forth or
incorporated by reference in the Prospectus,  there has been no material adverse
change in the financial  position or in the  financial  results of operations of
the Company,  except as set forth in or  contemplated  by the  Prospectus  or as
described in such certificate.

              (c) From the time solicitation  regarding the sale of the Notes is
begun  until  all of the Notes  have  been  sold,  at each  Representation  Date
referred to in Section 6(b) (i) or (ii) and, only if requested by the Agents, at
each  Representation Date referred to in Section 6(b) (iii) or (iv), the Company
shall  concurrently  furnish  the Agents  with a written  opinion or opinions of
counsel  for the  Company,  dated  the  Representation  Date or the date of such
filing,  in form  satisfactory to the Agents, to the effect set forth in Section
5(d) hereof, but modified, as necessary, to relate to the Registration Statement
and the Prospectus as then amended or supplemented;  provided,  however, that in
lieu of such opinion, counsel may furnish the Agents with a letter to the effect
that the Agents may rely on a prior opinion delivered under Section 5(d) or this
Section  6(c) to the same  extent as if it were  dated  the date of such  letter
(except that  statements  in such prior opinion shall be deemed to relate to the
Registration  Statement and the  Prospectus as amended or  supplemented  at such
Representation Date).

              (d) From the time solicitation  regarding the sale of the Notes is
begun  until  all of the Notes  have  been  sold,  at each  Representation  Date
referred to in Section 6(b) (i) or (ii) and, only if requested by the Agents, at
each  Representation Date referred to in Section 6(b) (iii) or (iv), but in each
case only if such  documents  referred  to in Section  6(b)  include  additional
financial  information,  the Company shall cause  PricewaterhouseCoopers  LLP or
successor  thereto  concurrently to furnish the Agents with a letter,  addressed
jointly to the Company and the

<PAGE>
                                      -14-
     Agents and dated the  Representation  Date or the date of such  filing,  in
form and  substance  satisfactory  to the  Agents,  to the  effect  set forth in
Section 5(f) hereof but modified to relate to the Registration Statement and the
Prospectus as amended or  supplemented  at such  Representation  Date, with such
changes as may be necessary to reflect  changes in the financial  statements and
other information derived from the accounting records of the Company;  provided,
however,  that if the  Registration  Statement or the  Prospectus  is amended or
supplemented  solely to  include  financial  information  as of and for a fiscal
quarter,  PricewaterhouseCoopers  LLP may limit the scope of such  letter to the
unaudited  financial  statements included in such amendment or supplement unless
there is  contained  therein  any other  accounting,  financial  or  statistical
information that, in the reasonable judgment of the Agents, should be covered by
such letter,  in which event such letter shall also cover such other information
and procedures as shall be agreed upon by the Agents.

              (e) On each  settlement  date for the sale of Notes,  the  Company
shall, if requested by an Agent that solicited or received the offer to purchase
any Notes being  delivered on such  settlement  date,  furnish such Agent with a
written  opinion  of a  counsel  for the  Company,  dated  the date of  delivery
thereof,  in form satisfactory to such Agent, to the effect set forth in clauses
(i),  (ii),  and (iii) of Section 5(d) hereof,  but modified,  as necessary,  to
relate to the Prospectus as amended or  supplemented at such settlement date and
except that such opinion shall state that the Notes being sold by the Company on
such settlement date, when delivered against payment therefor as provided in the
Indenture  and this  Agreement,  will have been  duly  executed,  authenticated,
issued and delivered and will constitute  valid and legally binding  obligations
of the Company  enforceable in accordance with their terms,  subject only to the
exceptions as to enforcement set forth in clauses (ii) and (iii) of Section 5(d)
hereof,  and conform to the description  thereof  contained in the Prospectus as
amended or supplemented at such settlement date.

              (f) The  Company  agrees that any  obligation  of a person who has
agreed to purchase  Notes to make  payment  for and take  delivery of such Notes
shall be subject  to (i) the  accuracy,  on the  related  settlement  date fixed
pursuant to the  Procedures,  of the Company's  representations  and  warranties
deemed to be made to the Agents  pursuant to Section 2 and the last  sentence of
subsection  (a) of this  Section 6; (ii) the  satisfaction,  on such  settlement
date, of each of the  conditions  set forth in Sections  5(a),  (b), and (c), it
being  understood  that under no  circumstance  shall any Agent have any duty or
obligation  to exercise  the  judgment  permitted  under  Section 5(b) or (c) on
behalf  of any such  person;  (iii) the  absence  of any  change or  development
involving a prospective change, not contemplated by the Prospectus as amended or
supplemented  to the trade  date as  specified  pursuant  to the  Administrative
Procedures,  in or  affecting  particularly  the business or  properties  of the
Company which materially  impairs the investment  quality of the Notes; and (iv)
no downgrading in the rating of the Company's debt

<PAGE>
                                      -15-

securities by any "nationally  recognized  statistical rating organization"
(as defined for purposes of Rule 436(g) under the Act).

      7.      Indemnification and Contribution.
              --------------------------------

              (a) The Company will  indemnify  and hold  harmless each Agent and
each person if any, who  controls  either Agent within the meaning of the Act or
the Exchange Act against any losses,  claims,  damages or liabilities,  joint or
several,  to which such  Agent or such  controlling  person may become  subject,
under  the Act,  or  otherwise,  insofar  as such  losses,  claims,  damages  or
liabilities  (or actions in respect  thereof) arise out of or are based upon any
untrue  statement or alleged untrue  statement of any material fact contained in
the  Registration  Statement  or  the  Prospectus,  or any  related  preliminary
prospectus or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements  therein not  misleading;  and will reimburse each Agent and each
such controlling person for any legal or other expenses  reasonably  incurred by
such  Agent or such  controlling  person in  connection  with  investigating  or
defending any such loss, claim, damage, liability or action; provided,  however,
that the Company will not be liable to such Agent or  controlling  person in any
such case to the extent that any such loss,  claim,  damage or liability  arises
out of or is based upon an untrue  statement  or  alleged  untrue  statement  or
omission or alleged  omission made in any such documents in reliance upon and in
conformity  with written  information  furnished to the Company by such Agent or
such controlling  person  specifically for use therein unless such loss,  claim,
damage or  liability  arises out of the offer or sale of Notes  occurring  after
such Agent or  controlling  person has notified the Company in writing that such
information should no longer be used therein.  This indemnity  agreement will be
in addition to any liability which the Company may otherwise have.

              (b) Each Agent will indemnify and hold harmless the Company,  each
of its  directors,  each  of its  officers  who  have  signed  the  Registration
Statement and each person,  if any, who controls the Company  within the meaning
of the  Act or  the  Exchange  Act,  against  any  losses,  claims,  damages  or
liabilities  to which the Company or any such  director,  officer or controlling
person may become subject, under the Act, or otherwise,  insofar as such losses,
claims,  damages or liabilities (or actions in respect  thereof) arise out of or
are based upon any untrue  statement or alleged untrue statement of any material
fact contained in the Registration  Statement or the Prospectus,  or any related
preliminary  prospectus  or arise out of or are based upon the  omission  or the
alleged  omission to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading,  in each case to the
extent,  but only to the extent,  that such untrue  statement or alleged  untrue
statement  or omission  or alleged  omission  was made in

<PAGE>
                                      -16-
     reliance upon and in conformity with written  information  furnished to the
Company by such Agent specifically for use therein; and will reimburse any legal
or other  expenses  reasonably  incurred  by the  Company or any such  director,
officer or controlling  person in connection with investigating or defending any
such loss,  claim,  damage,  liability or action as such  expenses are incurred;
provided, however, that such Agent will not be liable to the Company or any such
director,  officer or controlling person in any such case to the extent that any
such loss,  claim,  damage or liability arises out of the offer or sale of Notes
occurring  after  such Agent has  notified  the  Company  in  writing  that such
information should no longer be used therein.  This indemnity  agreement will be
in addition to any liability which such Agent may otherwise have.

              (c)  Promptly  after  receipt by an  indemnified  party under this
Section of notice of the  commencement  of any action,  such  indemnified  party
will, if a claim in respect thereof is to be made against the indemnifying party
under (a) and (b)  above,  notify  the  indemnifying  party of the  commencement
thereof;  but the omission so to notify the indemnifying  party will not relieve
it from any liability which it may have to any indemnified  party otherwise than
under this Section.  In case any such action is brought  against any indemnified
party, and it notifies the indemnifying party of the commencement  thereof,  the
indemnifying  party will be entitled to  participate  therein and, to the extent
that it may wish, jointly with any other indemnifying party similarly  notified,
to assume the defense  thereof,  with counsel  satisfactory to such  indemnified
party (who may,  with the consent of the  indemnified  party,  be counsel to the
indemnifying  party) and who shall not be counsel to any other indemnified party
who may have interests  conflicting  with those of such  indemnified  party, and
after  notice  from  the  indemnifying  party to such  indemnified  party of its
election so to assume the defense thereof,  the  indemnifying  party will not be
liable to such  indemnified  party  under  this  Section  for any legal or other
expenses  subsequently incurred by such indemnified party in connection with the
defense thereof other than reasonable costs of investigation.

              (d)  If   recovery   is  not   available   under   the   foregoing
indemnification  provisions  of  this  Section  for  any  reason  other  than as
specified therein,  the parties entitled to indemnification by the terms thereof
shall be entitled to  contribution  to liabilities  and expenses,  except to the
extent that  contribution  is not  permitted  under Section ll(f) of the Act. In
determining  the amount of  contribution  to which the  respective  parties  are
entitled, there shall be considered the relative benefits received by each party
from the offering of the Notes  (taking into account the portion of the proceeds
of the offering realized by each), the parties' relative knowledge and access to
information  concerning the matter with respect to which the claim was asserted,
the opportunity to correct and prevent any statement or omission,  and any other
equitable  considerations  appropriate under the circumstances.  The Company and
the Agents

<PAGE>
                                      -17-

     and such  controlling  persons  agree that it would not be equitable if the
amount of such contribution were determined by pro rata or per capita allocation
(even if the Agents and such controlling  persons were treated as one entity for
such purpose).  Notwithstanding  the provisions of this subsection (d), no Agent
or controlling person shall be required to make contribution  hereunder which in
the aggregate exceeds the total public offering price of the Notes,  distributed
to the public  through it  pursuant  to this  Agreement  or upon resale of Notes
purchased by it from the Company, less the aggregate amount of any damages which
such Agent or such  controlling  person has  otherwise  been  required to pay in
respect to the same claim or  substantially  similar claim.  No person guilty of
fraudulent  misrepresentation  (within the meaning of Section  11(f) of the Act)
shall be  entitled  to  contribution  from any person who was not guilty of such
fraudulent misrepresentation. The obligations of each Agent and each controlling
person in this subsection (d) to contribute are several,  in the same proportion
which the amount of the Notes which are the subject of the action and which were
distributed to the public through such Agent or such controlling person pursuant
to this  Agreement  bears to the total amount of such Notes  distributed  to the
public through any other Agent or controlling person pursuant to this Agreement,
and not joint.

      8. Status of Each Agent.  In soliciting  offers to purchase the Notes from
the Company  pursuant to this  Agreement  and in assuming its other  obligations
hereunder (other than offers to purchase  pursuant to Section 11), each Agent is
acting  individually  and not  jointly  and is  acting  solely  as agent for the
Company  and not as  principal.  Each Agent will use all  reasonable  efforts to
assist the Company in obtaining  performance  by each  purchaser  whose offer to
purchase Notes from the Company has been solicited by such Agent and accepted by
the Company,  but such Agent shall have no liability to the Company in the event
any such  purchase  is not  consummated  for any reason.  If the  Company  shall
default on its  obligations  to deliver Notes to a purchaser  whose offer it has
accepted, the Company (i) shall hold the Agents harmless against any loss, claim
or damage arising from or as a result of such default by the Company,  and (ii),
in  particular,  shall pay to the Agents any  commission  to which they would be
entitled in connection with such sale.

      9. Survival of Certain  Representations  and  Obligations.  The respective
indemnities, agreements, representations, warranties and other statements of the
Company or its officers and of the Agents set forth in or made  pursuant to this
Agreement will remain in full force and effect, regardless of any investigation,
or statement as to the results  thereof,  made by or on behalf of any Agent, the
Company or any of their respective representatives, officers or directors or any
controlling  person and will survive  delivery of and payment for the Notes.  If
this Agreement is terminated pursuant to Section 10 or for any other reason, the
Company shall remain responsible for the expenses to be paid or reimbursed by it
pursuant to Section 4(g) and the  obligations of the Company under Sections 4(f)
and (h) and the

<PAGE>
                                      -18-

     respective  obligations of the Company and the Agents pursuant to Section 7
shall remain in effect. In addition,  if any such termination shall occur either
(i) at a time when any Agent  shall own any of the Notes with the  intention  of
reselling them or (ii) after the Company has accepted an offer to purchase Notes
and prior to the related  settlement,  the  obligations of the Company under the
last sentence of Section 4(b), under Sections 4(a), 4(c), 4(d), 4(e), 6(a), 6(e)
and 6(f) and, in the case of a termination occurring as described in (ii) above,
under  Section 3(c) and under the last  sentence of Section 8, shall also remain
in effect.

      10.  Termination.  This  Agreement may be terminated for any reason at any
time by the  Company  as to any Agent or, in the case of either  Agent,  by such
Agent insofar as this  Agreement  relates to such Agent,  upon the giving of one
day's  written  notice of such  termination  to the other  parties  hereto.  Any
settlement with respect to Notes placed by an Agent occurring after  termination
of this Agreement shall be made in accordance with the Procedures and each Agent
agrees,  if requested by the Company,  to take the steps therein  provided to be
taken by such Agent in connection with such settlement.

      11. Other Sales and Purchases of Notes.  From time to time,  any Agent may
agree with the Company to purchase all or a portion of Notes from the Company as
an  underwriter  (acting  either  alone  or in  conjunction  with  one  or  more
investment banking firms) for resale to the public. In this event, such purchase
shall be made in accordance with the terms of a separate agreement to be entered
into  between  such Agent and the  Company in  substantially  the form  attached
hereto as Exhibit C.

              Without the oral  consent  (confirmed  in writing) of the Company,
neither Agent shall have the right to purchase all or a portion of the Notes for
its own  account.  In the event  the  Company  consents  to such  purchase,  the
purchase shall be made in accordance  with the terms of a separate  agreement to
be entered  into between  such Agent and the Company in  substantially  the form
attached hereto as Exhibit D.

              Nothing  in this  Agreement  shall  prohibit  the sale of all or a
portion of Notes  directly  by the  Company to any person or entity  without the
involvement  of either of the Agents or from  entering  into similar  agreements
with other firms as agents.

              The Company will not appoint another agent without  providing each
Agent with at least one business day's notice.

      12. Notices.  Except as otherwise  provided herein,  all notices and other
communications  hereunder  shall be in writing  and shall be deemed to have been
duly given if delivered by overnight mail or transmitted by any standard form of

                            ADMINISTRATIVE PROCEDURES

      The Medium-Term Notes,  Series B due from nine months to thirty years from
their  issue  dates (the  "Notes")  are to be offered on a  continuing  basis by
Constellation Energy Group, Inc. (the "Company").  Lehman Brothers Inc. Goldman,
Sachs & Co. and Merrill Lynch,  Pierce,  Fenner & Smith  Incorporated  as agents
(individually,  an "Agent" and  collectively,  the "Agents") have each agreed to
use all reasonable efforts to solicit purchases of the Notes. Neither Agent will
be obligated to purchase Notes for its own account and neither may do so without
the  written  consent of the  Company.  The Notes are being sold  pursuant to an
Agency Agreement, dated as of __________,  2000 (the "Agency Agreement"),  among
the Company and the Agents, and will be issued pursuant to an Indenture, between
the  Company  and  The  Bank  of New  York  dated  as of  March  24,  1999  (the
"Indenture").  The  Notes  will  rank  equally  with  all  other  unsecured  and
unsubordinated  indebtedness  of the Company and will have been  registered with
the Securities and Exchange Commission (the "Commission").

              The Company has  designated  The Bank of New York (the  "Bank") as
the  agency  for  payment,  registration  and  notice  concerning  the  Notes in
accordance  with Section 5.02 of the Indenture and as the  Authentication  Agent
for the Notes in accordance with Section 2.02 of the Indenture.  The Company has
also designated the Bank as the  Calculation  Agent with respect to the issuance
of floating rate notes  pursuant to the Interest  Calculation  Agency  Agreement
between the Company and the Bank dated __________, 2000.

              Administrative  procedures  and specific terms of the offering are
explained below.  Internal  administrative and  record-keeping  responsibilities
will be handled for the Company by its Financial  Management Unit of the Finance
Department.  The  Company  will  advise the  Agents in writing of those  persons
handling administrative responsibilities with whom the Agents are to communicate
regarding  offers to purchase  Notes and the details of their  delivery.  Unless
otherwise  designated,  the Notes will be issued as Global Securities registered
in the name of The Depository Trust Company or a nominee thereof (referred to as
"Book Entry Notes"). Procedures pertaining specifically to Book-Entry Notes and,
as the case may be, Notes issued in definitive form ("Certificated  Notes") will
be explained separately below.

Aggregate

Principal Amount:           $500,000,000

Issue Date:                 Each  Note will be dated  the date of its
                            authentication.  Each Note will also bear an
                            original  issue date (the "Issue  Date")  which,
                            with  respect to any Note (or portion thereof),
                            shall  mean  the  date of its  original  issuance
                            and shall  be  specified therein.  The Issue Date
                            shall remain the same for all Notes

                            subsequently  issued upon transfer,   exchange  or
                            substitution  of  a Note,   regardless  of  their
                            dates  of authentication.


Maturities:                 Each Note will mature on a Business  Day (as defined
                            below),  selected by the  purchaser and agreed to by
                            the  Company,  which will range from nine  months to
                            thirty years after the Issue Date. Each Note bearing
                            interest at a rate  determined  by  reference  to an
                            interest rate formula (a "Floating  Rate Note") will

                            below).

                            "Business  Day"  means any day other than a Saturday
                            or  Sunday  that (a) is not a day on  which  banking
                            institutions in Maryland,  or in New York, New York,

                            order to be  closed,  and (b) with  respect to LIBOR
                            Notes only,  is a day on which  dealings in deposits
                            in  U.S.   dollars  are  transacted  in  the  London
                            interbank market.

Price to Public:            Each Note will be issued at 100% of principal
                            amount (unless  otherwise  indicated in a pricing
                            supplement).


Denominations:              The  minimum  denominations  of the  Notes  will  be
                            $1,000 and  integral  multiples  of $1,000 in excess
                            thereof  (see  "Special  Procedures  for  Book-Entry
                            Notes - Denominations"  for information  relating to
                            Book-Entry Notes).

Registration:               Notes will be issued only in fully  registered
                            form as either a  Book-Entry  Note or a Certificated
                            Note.  Certificated  Notes may be presented for
                            registration of transfer or exchange at the Bank's
                            New York office.


Interest Payments:          Each Note  bearing  interest at a fixed rate (a
                            "Fixed  Rate Note") will bear  interest from its
                            Issue Date if  interest  has not been paid on the
                            Note or from the most recent Interest  Payment  Date
                            to which  interest  has been paid at the  fixed
                            rate per annum stated on the face  thereof,  payable
                            semi-annually  on May 1 and  November  1 of each
                            year (each an "Interest  Payment  Date" with
                            respect to such Fixed Rate Note),  and at Stated
                            Maturity, and, if applicable, upon redemption or
                            repurchase.

                            Special  provisions  are set forth in the Prospectus
                            relating to Floating Rate Notes.  Interest rates are
                            determined by reference to the interest rate formula
                            stated  therein and payable in arrears on such dates
                            as  specified  therein  (each an  "Interest  Payment
                            Date" with respect to such Floating Rate Note).

                            Interest on Fixed Rate Notes (including payments for
                            partial  periods)  will be computed  and paid on the
                            basis of a 360-day year of twelve  30-day months and
                            will  not  accrue  on the  31st  day  of any  month.
                            Interest will be payable to the person in whose name
                            the Note is  registered  at the close of business on
                            April 15 or October 15, (whether or not such date is
                            a Business  Day) with respect t

                                      -B3-

                            Fixed Rate Notes or the  fifteenth  day (whether or
                            not a Business  Day) with  respect to
                            Floating  Rate Notes (the  "Record
                            Dates"),  next  preceding  the  respective  Interest
                            Payment  Date;  provided,   however,  that  interest
                            payable at Stated Maturity and, if applicable,  upon
                            redemption  or  repurchase  will be  payable  to the
                            person to whom principal shall be payable. The first
                            payment of  interest on any Note  originally  issued
                            between a Record Date and an Interest  Payment  Date
                            will be made on the Interest  Payment Date following
                            the  next  succeeding   Record  Date.  All  interest
                            payments (excluding interest payments made at Stated
                            Maturity and, if  applicable,  upon  redemption  and
                            repurchase)  will  be made by  check  mailed  to the
                            person entitled  thereto as provided  above;  except
                            that holders of over $5 million in principal  amount
                            of the Notes may receive  interest  payments by wire
                            upon at least three Business Day's written notice to
                            the Bank.

                            On the fifth Business Day immediately preceding each
                            Interest  Payment  Date,  the Bank will  furnish the
                            Company  with  the  total  amount  of  the  interest
                            payments to be made on such  Interest  Payment Date.
                            The  Bank  will  provide  monthly  to the  Company's
                            Financial  Services Unit a list of the principal and
                            interest  to be paid on Notes  maturing  in the next
                            succeeding  month.  On  the  Interest  Payment  Date
                            (unless the Interest  Payment Date is not a Business
                            Day, then the immediately  succeeding Business Day),
                            the  Company  will  transfer  to the  Bank,  via the
                            Federal Reserve wire system,  immediately  available
                            funds sufficient to make such interest payments. The
                            Bank  will  assume  responsibility  for  withholding
                            taxes on interest paid as required by law.

Acceptance                  of  Offers:  Each  Agent  will  promptly  advise the
                            Company of each  reasonable  offer to purchase Notes
                            received  by it,  other than those  rejected by such
                            Agent. Each Agent may, in its discretion  reasonably
                            exercised, without notice to the Company, reject any
                            offer  received  by it,  in whole  or in  part.  The
                            Company will have the sole right to accept offers to
                            purchase  Notes and may  reject any such  offer,  in
                            whole or in part.  If the Company  rejects an offer,
                            the Company will promptly notify the Agent involved.

Settlement:                 All offers  accepted by the Company  will be settled
                            on the third  Business Day next  succeeding the date
                            of  acceptance   unless   otherwise  agreed  by  any
                            purchaser and the Company. The settlement date shall
                            be specified upon receipt of an offer.

Confirmation:               For each accepted offer,  the Presenting  Agent will
                            issue a confirmation  to the purchaser,  with a copy
                            to the  Company's  Financial  Services  Unit and the
                            Bank,  setting  forth the Purchase  Information  and
                            delivery and payment instructions.

Redemption at
Company's  Option:          Except as  otherwise  specified  in the  applicable
                            Pricing Supplement  and on the Notes,  the Notes
                            will not be  redeemable  prior to their Stated
                            Maturity. If so specified,  such Note will be
                            redeemable at the option of the Company on or after
                            a specified  date at a specified  price or prices
                            (which may include a

<PAGE>
                                      -B4-

          premium)  together  with  accrued  interest  thereon  payable  to, but
          excluding, the date fixed for redemption. The Notes will be redeemable
          in whole or in part (whether or not any other Notes of the same series
          are  redeemed),  in  increments  of $1,000 on notice by mail given not
          more  than 60 nor  less  than 30 days  prior  to the  date  fixed  for
          redemption.  If there is a partial  redemption,  the Bank will issue a
          new Note on the same terms.

          Upon  presentation of each Note at the date fixed for redemption,  the
          Bank (or any other duly appointed paying agent) will pay the principal
          amount (at a price,  expressed as a percent of the  principal  amount,
          specified  on  the  Note  and in the  applicable  Pricing  Supplement)
          redeemed  thereof,  together  with accrued  interest due on the amount
          redeemed at the date fixed for redemption.  Such payment shall be made
          in immediately available funds, provided that the Note is presented to
          the Bank (or any such paying  agent) in time for the Bank (or any such
          paying agent) to make  payments in such funds in  accordance  with its
          normal  procedures.  On the date fixed for redemption (unless the date
          fixed for  redemption  is not a  Business  Day,  then the  immediately
          succeeding  Business  Day), the Company will provide the Bank (and any
          such paying agent), via the Federal Reserve wire transfer system, with
          immediately  available  funds  sufficient  for the  Bank to make  such
          payment.  Notes  presented  at the date fixed for  redemption  will be
          canceled by the Bank as provided in the Indenture.

Repurchase at
Holder's  Option:
          Except as otherwise specified in the applicable Pricing Supplement and
          on the Notes, the Company is not required to repurchase the Notes from
          the holders prior to the Stated Maturity. If so specified,  Notes will
          be  redeemable  at the option of the holder,  in whole or in part,  in
          increments  of  $1,000,  on the  dates  and at  the  prices  specified
          therein,  together  with  accrued  interest  to,  but  excluding,  the
          repurchase date. For Book-Entry Notes,  holders must deliver a written
          notice to the Bank at least 30,  but no more than 60 days prior to the
          date of repurchase,  but no later than 5:00 p.m. New York City time on
          the last day for giving  notice.  The written  notice must specify the
          principal  amount  to be  repurchased  and  must be  signed  by a duly
          authorized  signatory of the Depositary  (signature  guaranteed).  For
          Certificated  Notes,  holders  must  complete  the  "Option  to  Elect
          Repayment" on the reverse of the Note and then deliver the Note to the
          Bank at least 30,  but no more  than 45 days  prior to the date of the
          repurchase, but no later than 5:00 p.m. New York City time on the last
          day for giving  notice.  All  notices are  irrevocable.  If there is a
          partial redemption, the Bank will issue a new Note on the same terms.

          On the repurchase  date, the Bank (or any other duly appointed  paying
          agent)  will  repurchase  the Note from the  holder  at the  specified
          price,  together  with any  accrued  interest,  payment  to be made in
          immediately  available  funds.  The Company will provide the Bank (and
          any such paying agent),  via the Federal Reserve wire transfer system,
          with immediately  available funds sufficient for the Bank to make such
          repurchases.  Repurchased  Notes  will  be  canceled  by the  Bank  as
          provided in the Indenture.

Remarketed Notes        Procedures related to Remarketed Notes will be added
                        at the time any notes are issued.


Maturity:               Upon  presentation  of each  Note at  maturity  the
                        Bank (or any other  duly  appointed paying agent) will
                        pay the principal  amount thereof,  together with
                        accrued  interest due at maturity.  Such payment shall
                        be made in immediately  available funds,  provided
                        that the Note is  presented  to the Bank  (or any such
                        paying  agent)  in time for the Bank (or any such
                        paying agent) to make  payments in such funds in
                        accordance  with its normal  procedures.  On the
                        maturity  date,  the Company will provide the Bank (and
                        any such paying agent),  via the Federal  Reserve wire
                        transfer  system,  with  immediately available  funds
                        sufficient  for the Bank to make such  payment.  Notes
                        presented  at maturity will be canceled by the Bank as
                        provided in the Indenture.

Procedure for
Rate or Redemption
Changes:                The  Company and the Agents  will  discuss  from time
                        to time the rates to be borne by, and the redemption
                        and  repurchase  provisions,  if any, of, the Notes that
                        may be sold as a result of the  solicitation  of offers
                        by the Agents.  Once any Agent has recorded any
                        indication  of interest in Notes upon certain  terms,
                        and  communicated  with the Company,  if the Company
                        plans to accept an offer to  purchase  Notes upon such
                        terms, it will  prepare a sticker  reflecting  the terms
                        of such Notes and,  after  confirming such terms with
                        such Agent,  will  arrange to have the  Prospectus,  as
                        then amended or supplemented,  and bearing such sticker,
                        filed with the  Commission and will supply at least 10
                        copies of the Prospectus,  as then amended or
                        supplemented,  and bearing such sticker,  to the
                        Presenting  Agent.  No  settlements  with  respect to
                        Notes upon such terms may occur  prior to such filing
                        and the Agents  will not,  prior to such  filing,
                        mail  confirmations  to customers  who have offered to
                        purchase  Notes upon such terms.  After such filing,
                        sales,  mailing of  confirmations  and  settlements
                        may occur with respect  to  Notes  upon  such  terms,
                        subject  to  the  provisions  of  "Delivery  of
                        Prospectus" below.

          If the Company  decides to post rates  (which may include the presence
          or absence of redemption and repurchase provisions) and a decision has
          been reached to change  interest  rates or  redemption  or  repurchase
          provisions,  if any, the Company will promptly notify each Agent. Each
          Agent will forthwith suspend solicitation of purchases.  At that time,
          the Agents will recommend and the Company will  establish  rates to be
          so "posted." Following  establishment of posted rates and prior to the
          filing described in the following sentence, the Agents may only record
          indications of interest in purchasing Notes at the posted rates.  Once
          any Agent has  recorded  any  indication  of  interest in Notes at the
          posted rates and communicated  with the Company,  if the Company plans
          to  accept  an offer at the  posted  rate,  it will  prepare a sticker
          reflecting  such posted rates and,  after  confirming  such terms with
          such Agent,  will  arrange to have the  Prospectus,  and bearing  such
          sticker,  filed with the Commission and will supply at least 10 copies
          of the Prospectus, as then amended or supplemented,  to the Presenting
          Agent.  No  settlements  at the posted  rates may occur  prior to such
          filing  and  the  Agents  will  not,   prior  to  such  filing,   mail
          confirmations to

<PAGE>
- -B6-

          customers  who have  offered to  purchase  Notes at the posted  rates.
          After such filing, sales, mailing of confirmations and settlements may
          resume, subject to the provisions of "Delivery of Prospectus" below.

          Outdated  stickers,  and  copies of the  Prospectus  to which they are
          attached (other than those retained for files), will be destroyed.

Suspension of
Solicitation;
Amendment or

Supplement:
          As  provided  in  the  Agency  Agreement,   the  Company  may  suspend
          solicitation  of purchases  at any time and,  upon receipt of at least
          one Business Day's prior notice from the Company, the Agents will each
          forthwith  suspend  solicitation  until such time as the  Company  has
          advised them that solicitation of purchases may be resumed.

          If the Agents  receive  the notice from the  Company  contemplated  by
          Section  4(b) of the  Agency  Agreement,  they will  promptly  suspend
          solicitation  and will only  resume  solicitation  as  provided in the
          Agency  Agreement.  If the Company  decides to amend or supplement the
          Registration  Statement or the  Prospectus  relating to the Notes,  it
          will  promptly  advise each Agent and will furnish each Agent with the
          proposed  amendment or supplement in accordance  with the terms of the
          Agency  Agreement.  The Company will promptly  file such  amendment or
          supplement;  provide the Agents with copies of any such  amendment  or
          supplement;  confirm to the Agents that such  amendment or  supplement
          has been  filed  with the  Commission;  and  advise  the  Agents  that
          solicitation may be resumed.

          Any such suspension shall not affect the Company's  obligations  under
          the Agency  Agreement;  and in the event that at the time the  Company
          suspends  solicitation  of purchases there shall be any offers already
          accepted by the Company  outstanding for settlement,  the Company will
          have the sole  responsibility  for fulfilling  such  obligations.  The
          Company  will in addition  promptly  advise the Agents and the Bank if
          such offers are not to be settled and if copies of the  Prospectus  as
          in  effect  at the  time of the  suspension  may not be  delivered  in
          connection with the settlement of such offers.

Delivery of
Prospectus:

          A copy of the Prospectus,  as most recently amended or supplemented on
          the date of  delivery  thereof  (except as  provided  below),  must be
          delivered  to a  purchaser  prior to or  together  with the earlier of
          delivery of (i) the written confirmation  provided for above, and (ii)
          any Note  purchased by such  purchaser.  The Company shall ensure that
          the  Presenting  Agent  receives  copies  of the  Prospectus  and each
          amendment  or  supplement  thereto  (including   appropriate   pricing
          stickers)  in such  quantities  and  within  such time  limits as will
          enable the Presenting Agent to deliver such  confirmation or Note to a
          purchaser as contemplated  by these  procedures and in compliance with
          the  preceding  sentence.  If,  since  the  date  of  acceptance  of a
          purchaser's offer, the Prospectus shall have been supplemented  solely
          to reflect any sale of Notes on

<PAGE>
- -B7-

          terms  different  from those  agreed to between  the  Company and such
          purchaser  or  a  change  in  posted  rates  not  applicable  to  such
          purchaser,   such  purchaser  shall  not  receive  the  Prospectus  as
          supplemented by such new supplement,  but shall receive the Prospectus
          as  supplemented  to reflect the terms of the Notes being purchased by
          such purchaser and otherwise as most recently  amended or supplemented
          on the date of delivery of the Prospectus.

Authenticity of
Signatures:
          The  Company  will cause the Bank to furnish  the Agents  from time to
          time with the  specimen  signatures  of each of the  Bank's  officers,
          employees  or  agents  who  have  been   authorized  by  the  Bank  to
          authenticate  Notes,  but  the  Agents  will  have  no  obligation  or
          liability to the Company or the Bank in respect of the authenticity of
          the signature of any officer,  employee or agent of the Company or the
          Bank on any Note.

          Advertising  Cost:  The  Company  will  determine  with the Agents the
          amount of  advertising  that may be appropriate in offering the Notes.
          Advertising expenses will be paid by the Company.


II.  Special Procedures for Book-Entry Notes

          Each Note may be represented by either a Global Security  delivered to
          the Bank,  as agent for the  Depository  Trust  Company  ("DTC"),  and
          recorded in the book-entry  system  maintained by DTC or a certificate
          delivered to the Holder thereof or a Person designated by such Holder.
          An owner of a  Book-Entry  Note  will not be  entitled  to  receive  a
          certificate   representing   such  Note.   In   connection   with  the
          qualification   of  the  Book-Entry   Notes  for  eligibility  in  the
          book-entry  system  maintained  by DTC,  the  Bank  will  perform  the
          custodial,  document control and  administrative  functions  described
          below, in accordance with its respective obligations under a Letter of
          Representations from the Company and the Bank to DTC and a Medium-Term
          Note Certificate  Agreement  previously  entered into between the Bank
          and DTC, and its obligations as a participant in DTC,  including DTC's
          Same-Day Funds  Settlement  System  ("SDFS").  Except as otherwise set
          forth in this Exhibit B, Book-Entry Notes will be issued in accordance
          with the administrative procedures set forth in this section.

Issuance:
          On any date of settlement (as defined under  "Settlement"  below), for
          one or more Fixed Rate  Book-Entry  Notes,  the  Company  will issue a
          single  Global  Security  in fully  registered  form  without  coupons
          representing up to $400,000,000  principal amount of all of such Notes
          that have the same original  issuance  date,  interest rate and Stated
          Maturity.  Similarly,  on any settlement date for one or more Floating
          Rate Book-Entry Notes, the Company will issue a single Global Security
          representing up to $400,000,000  principal amount of all of such Notes
          that have the same  interest  rate formula,  original  issuance  date,
          Initial Interest Rate, Interest Payment Dates, Index Maturity,  Spread
          or Spread Multiplier, minimum interest rate (if any), maximum interest
          rate (if any) and Stated Maturity.  Each Global Security will be dated
          and issued as of the date of

<PAGE>
                                      -B8-

          its  authentication by the Bank, as authenticating  agent. Each Global
          Security  will have an interest  accrual date (the  "Interest  Accrual
          Date"),  which will be (i) with respect to an original Global Security
          (or any portion  thereof),  its original  issuance  date and (ii) with
          respect  to  any  Global   Security   (or  portion   thereof)   issued
          subsequently  upon  exchange  of a  Global  Security  or in  lieu of a
          destroyed,  lost or stolen Global  Security,  the most recent Interest
          Payment Date to which  interest has been paid or duly  provided for on
          the  predecessor  Global Security or Securities (or if no such payment
          or  provision  has  been  made,  the  original  issuance  date  of the
          predecessor Global Security), regardless of the date of authentication
          of such subsequently  issued Global Security.  No Global Security will
          represent  (i) both Fixed Rate and Floating Rate  Book-Entry  Notes or
          (ii) any Certificated Note.

Identification Numbers:
          The Company will arrange, on or prior to commencement of a program for
          the offering of Book-Entry  Notes,  with the CUSIP  Service  Bureau of
          Standard & Poor's  Corporation  (the "CUSIP  Service  Bureau") for the
          reservation of a series of CUSIP numbers  (including tranche numbers),
          consisting of  approximately  900 CUSIP numbers and relating to Global
          Securities  representing the Book-Entry Notes. The Company will obtain
          from  the  CUSIP  Service  Bureau a  written  list of such  series  of
          reserved  CUSIP  numbers  and  will  deliver  to the Bank and DTC such
          written  list of 900 CUSIP  numbers of such  series.  The Company will
          assign CUSIP  numbers to Global  Securities  as described  below under
          Settlement  Procedure  "B." DTC will notify the CUSIP  Service  Bureau
          periodically  of the CUSIP  numbers  that the Company has  assigned to
          Global  Securities.  At any time when fewer  than 100 of the  reserved
          CUSIP numbers remain unassigned to Global Securities,  and if it deems
          necessary,  the Company  will  reserve  additional  CUSIP  numbers for
          assignment to Global  Securities  representing  Book-Entry Notes. Upon
          obtaining such additional CUSIP numbers the Company shall deliver such
          additional CUSIP numbers to the Bank and DTC.

Registration:
          Each Global  Security will be registered in the name of Cede & Co., as
          nominee  for DTC,  on the  Securities  Register  maintained  under the
          Indenture  governing such Global  Security.  The beneficial owner of a
          Book-Entry  Note  (or  one  or  more  indirect   participants  in  DTC
          designated by such owner) will designate one or more  participants  in
          DTC (with respect to such Note, the "Participants") to act as agent or
          agents  for  Such  owner in  connection  with  the  book-entry  system
          maintained  by  DTC,  and DTC  will  record  in  book-entry  form,  in
          accordance with instructions  provided by such Participants,  a credit
          balance with respect to such Note in the account of such Participants.
          The ownership  interest of such beneficial  owner in such Note will be
          recorded  through  the  records of such  Participants  or through  the
          separate  records  of  such  Participants  and  one or  more  indirect
          participants in DTC.

Transfers:
          Transfers of a Book-Entry  Note will be  accomplished  by book entries
          made by DTC and, in turn, by Participants  (and in certain cases,  one
          or more indirect  participants  in DTC) acting on behalf of beneficial
          transferors and transferees of such Note.

Consolidation
and Exchange:
          The Bank may deliver to DTC and the CUSIP Service Bureau at any time a
          written  notice of  consolidation  specifying (i) the CUSIP numbers of
          two or more  Outstanding  Global  Securities  that represent (A) Fixed
          Rate Book-Entry Notes having the same original issuance date, interest
          rate and Stated  Maturity and with respect to which  interest has been
          paid to the same date or (B) Floating Rate Book-Entry Notes having the
          same interest rate formula,  original issuance date,  Initial Interest
          Rate,  Interest  Payment  Dates,  Index  Maturity,  Spread  or  Spread
          Multiplier,  minimum interest rate (if any), maximum interest rate (if
          any) and Stated  Maturity and with respect to which  interest has been
          paid to the same date,  (ii) a date,  occurring  at least  thirty days
          after such written notice is delivered and at least thirty days before
          the next Interest  Payment Date for such  Book-Entry  Notes,  on which
          such Global  Securities  shall be exchanged  for a single  replacement
          Global  Security  and  (iii) a new  CUSIP  number,  obtained  from the
          Company,  to be assigned to such  replacement  Global  Security.  Upon
          receipt of such a notice, DTC will send to its participants (including
          the Bank) a written  reorganization  notice  to the  effect  that such
          exchange  will occur on such  date.  Prior to the  specified  exchange
          date,  the Bank will  deliver  to the CUSIP  Service  Bureau a written
          notice  setting  forth such exchange date and the new CUSIP number and
          stating  that,  as of such  exchange  date,  the CUSIP  numbers of the
          Global  Securities  to be  exchanged  will no longer be valid.  On the
          specified exchange date, the Bank will exchange such Global Securities
          for a single  Global  Security  bearing the new CUSIP number and a new
          Interest  Accrual Date, and the CUSIP numbers of the exchanged  Global
          Securities  will, in accordance with CUSIP Service Bureau  procedures,
          be  canceled  and  not  immediately  reassigned.  Notwithstanding  the
          foregoing,   if  the  Global   Securities   to  be  exchanged   exceed
          $400,000,000 in aggregate  principal amount,  one Global Security will
          be  authenticated   and  issued  to  represent  each  $400,000,000  of
          principal amount of the exchanged Global  Securities and an additional
          Global  Security  will be  authenticated  and issued to represent  any
          remaining   principal   amount   of  such   Global   Securities   (see
          "Denominations" below).

Denominations:
          Book-Entry Notes will be issued in principal amount of $1,000,  or any
          amount in excess  thereof  that is an  integral  multiple  of  $1,000.
          Global  Securities  representing  one or more Book-Entry Notes will be
          denominated in principal amounts not in excess of $400,000,000.

Interest:
          General.  Interest  on each  Book-Entry  Note  will  accrue  from  the
          Interest Accrual Date of the Global Security  representing  such Note.
          Each  payment of interest on a Book-Entry  Note will include  interest
          accrued through the date  preceding,  as the case may be, the Interest
          Payment Date, Stated Maturity or redemption;  provided,  however, that
          if the Interest Reset Dates with respect to any such Note are daily or
          weekly,  interest  payable on any Interest  Payment  Date,  other than
          interest  payable  on any date on  which  principal  for such  Note is
          payable,  will include  interest accrued from but excluding the second
          preceding Record Date to and including the next preceding Record Date.
          Interest  payable  at the  Stated  Maturity  or upon  redemption  of a
          Book-Entry Note will be payable to the Person to whom the principal of
          such Note is

          received in the pending  deposit message  described  under  Settlement
          Procedure  "C" below in order to include  the  amount of any  interest
          payable and certain other  information  regarding  the related  Global

          Regular  Record Dates and Interest  Payment Dates that will occur with

          beginning on such first  Business  Date.  Promptly after each Interest
          Determination  Date (as defined in the  Prospectus)  for Floating Rate
          Notes,  the Bank,  acting as the  calculation  agent for Floating Rate

          confirm the amount  payable on each Global  Security on such  Interest
          Payment  Date by  reference  to the daily bond  reports  published  by

          Payment  Date  (other  than at  Maturity),  and the Bank will pay such
          amount to DTC at the times and in the  manner  set forth  below  under

          Security  and  deliver it to the  Company  with an  appropriate  debit

                            Procedure  "A" is completed,  Settlement  Procedures
                            "B" and "C" shall be  completed as soon as such rate

                            is  subject  to  extension  in  accordance  with any
                            extension of Fedwire  closing  deadlines  and in the
                            other  events   specified  in  the  SDFS   operating

                            cancellation message to such effect by no later than
                            2:00 P.M. on the Business Day immediately  preceding

Failure to Settle:
          If the Bank fails to enter an SDFS  deliver  order  with  respect to a
          Book-Entry  Note  pursuant to Settlement  Procedure  "F," the Bank may
          deliver to DTC, through DTC's Participant  Terminal System, as soon as
          practicable a withdrawal message instructing DTC to debit such Note to
          the  Bank's  participant  account.  DTC will  process  the  withdrawal
          message  provided  that the  Bank's  participant  account  contains  a
          principal amount of the Global Security representing such Note that is
          at least equal to the principal amount to be debited.  If a withdrawal
          message  is  processed  with  respect  to  all  the  Book-Entry  Notes
          represented  by a Global  Security,  the Bank will  mark  such  Global
          Security  "canceled," make  appropriate  entries in the Bank's records
          and send such canceled Global Security t the Company. The CUSIP number
          assigned to such  Global  Security  shall,  in  accordance  with CUSIP
          Service Bureau procedures,  be canceled and no immediately reassigned.
          If a withdrawal  message is processed with respect to one or more, but
          not all, of the Book-Entry Notes represented by a Global Security, the
          Bank will exchange such Global Security for two Global Securities, one
          of which shall  represent such  Book-Entry  Note or Notes and shall be
          canceled  immediately  after  issuance  and the  other of which  shall
          represent the other  Book-Entry  Notes  previously  represented by the
          surrendered  Global  Security  and shall bear the CUSIP  number of the
          surrendered Global Security.

          If the purchase  price for any  Book-Entry  Note is not timely paid to
          the  Participants   with  respect  to  such  Note  by  the  beneficial
          purchasers thereof (or a Person,  including an indirect participant in
          DTC, acting on behalf of such purchaser),  such  Participants  and, in
          turn,  the Agent for such Note may enter SDFS deliver  orders  through
          DTC's  Participant   Terminal  System  reversing  the  orders  entered
          pursuant  to  Settlement   Procedures   "F"  and  "G,"   respectively.
          Thereafter,  the Bank will deliver the withdrawal message and take the
          related actions described in the preceding paragraph.

          Notwithstanding the foregoing, upon any failure to settle with respect
          to a Book-Entry  Note, DTC may take any actions in accordance with its
          SDFS operating procedures then in effect. In the event of a failure to
          settle with  respect to one or more,  but not all,  of the  Book-Entry
          Notes to have been  represented  by a Global  Security,  the Bank will
          provide,  in  accordance  with  Settlement   Procedure  "D,"  for  the
          authentication  and  issuance of a Global  Security  representing  the
          other  Book-Entry  Notes  to have  been  represented  by  such  Global
          Security and will make appropriate entries in its records.

III. Special Procedures for Certificated Notes

                            from the Presenting  Agent,  the Company will, after
                            recording    the   details    and   any    necessary
                            calculations,  confirm the Purchase  Information  by
                            telephone,    facsimile    transmission   or   other
                            acceptable means, to the Bank.

                  C.        The Bank will  complete  the Note
                            assigning  to and  entering  on, each Note a

                            the  Company.  The  Bank  will  retain a copy of the
                            Note.  The  Presenting  Agent  will cause to be wire
                            transferred  to a  bank  account  designated  by the
                            Company immediately available funds in the amount of
                            the  principal  of the  Notes,  less the  applicable
                            commission.

                  E.        The Presenting  Agent, as the Company's agent,  will
                            deliver the Notes against payment by such purchasers
                            in  immediately  available  funds  in the  principal
                            amount of the Notes. Delivery of any confirmation or
                            a Note will be made in compliance  with "Delivery of
                            Prospectus."

                  F.        The  Bank  will  automatically  forward  a copy  of
                            the  Notes  to the  Company  unless
                            notified of a fail (See "Fails").

                                           the Settlement Date

Fails:
          In the event that a  purchaser  shall fail to accept  delivery  of and
          make payment for a Note on the settlement  date, the Presenting  Agent
          will  notify the Bank and the  Company,  by  telephone,  confirmed  in
          writing.  If the Note has been delivered to the Presenting  Agent,  as
          the Company's  agent,  the Presenting  Agent shall return such Note to
          the Bank.  If funds have been  advanced for the purchase of such Note,
          the Agent  will,  immediately  upon  receipt of such  Note,  debit the
          account of the  Company  for the amount so  advanced  and the  Company
          shall refund the payment  previously  made by the Presenting  Agent in
          immediately  available  funds.  Such  payments  will  be  made  on the
          settlement  date,  if  possible,  and in any event not later  than the
          Business Day  following the  settlement  date. If such fail shall have
          occurred for any reason other than the failure of the Presenting Agent
          to provide a confirmation to the purchaser, the Company will reimburse
          the Presenting  Agent on an equitable basis for its loss of the use of
          funds during the period when they were  credited to the account of the
          Company.  Immediately upon receipt of the Note in respect of which the
          fail occurred,  the Bank will make appropriate  entries to reflect the
          fact that the Note was never issued and will mark the Note "Canceled."
          The  Presenting  Agent will not be  entitled  to any  commission  with
          respect  to any Note  which  the  purchaser  does not  accept  or make
          payment for.

                        CONSTELLATION ENERGY GROUP, INC.
                          STANDARD PURCHASE PROVISIONS

               From time to time,  Constellation  Energy Group, Inc., a Maryland
corporation  ("Company") may enter into purchase agreements that provide for the
sale of designated  securities to the purchaser or purchasers named therein. The
standard  provisions  set forth herein may be  incorporated  by reference in any
such  purchase  agreement  ("Purchase   Agreement").   The  Purchase  Agreement,
including the provisions  incorporated therein by reference, is herein sometimes
referred to as "this Agreement." Unless otherwise defined herein,  terms defined
in the Purchase Agreement are used herein as therein defined.

               1. Introductory. The Company proposes to issue and sell from time
to  time  its  Medium-Term  Notes,  Series  B  ("Notes")  registered  under  the
registration  statement  referred to in Section  2(a).  The Notes will be issued
under an Indenture,  dated as of March 24, 1999 between the Company and The Bank
of New  York , as  Trustee  (the  "Indenture").  The  Notes  will be sold to the
Purchasers for resale in accordance with the terms of the offering determined at
the time of the sale.  The Notes  involved in any such offering are  hereinafter
referred to as the "Purchased Notes," and the firm or firms, as the case may be,
which agree to purchase the same are hereinafter referred to as the "Purchasers"
of such Purchased  Notes.  The terms "you" and "your" refer to those  Purchasers
who sign the Purchase Agreement either on behalf of themselves only or on behalf
of themselves and as representatives of the several Purchasers named in Schedule
A thereto, as the case may be.

               2.     Representations  and  Warranties of the Company.  The
        Company  represents and warrants to and agrees with each Purchaser that:
               (a) A  registration  statement  on Form S-3 (No.  333-__________)
        covering  $500  million  principal  amount  of the  Notes,  including  a
        prospectus has been filed with the  Securities  and Exchange  Commission
        ("Commission")   and  has  become  effective.   The  terms  Registration
        Statement and Prospectus shall have the meanings ascribed to them in the
        Purchase Agreement.

               (b) The  Registration  Statement  conforms in all respects to the
        requirements of the Securities Act of 1933, as amended ("Act"),  and the
        pertinent  published rules and regulations of the Commission  thereunder
        ("33 Act Rules and Regulations") and the Trust Indenture Act of 1939, as
        amended  ("Trust  Indenture  Act"),  and does  not  include  any  untrue
        statement of a material fact or omit to state any material fact required
        to be stated  therein or  necessary to make the  statements  therein not
        misleading,  except that the  foregoing  does not apply to statements or
        omissions in such document based upon written  information  furnished to
        the Company by any Purchaser specifically for use therein. The documents
        incorporated  by

<PAGE>
                                      -2-
        reference  in  the   Registration   Statement  or  the
        Prospectus  pursuant to Item 12 of Form S-3 of the Act, at the time they
        were filed with the Commission,  complied in all material  respects with
        the  requirements  of the  Securities  Exchange Act of 1934,  as amended
        ("Exchange  Act"),  and the pertinent  published  rules and  regulations
        thereunder  ("Exchange  Act  Rules  and  Regulations").  Any  additional
        documents deemed to be incorporated by reference in the Prospectus will,
        when they are filed with the Commission, comply in all material respects
        with the requirements of the Exchange Act and the Exchange Act Rules and
        Regulations and will not contain an untrue  statement of a material fact
        or omit to state a  material  fact  required  to be  stated  therein  or
        necessary to make the statements  therein, in light of the circumstances
        under which they were made, not misleading.

               3.  Delivery and Payment.  The Company will deliver the Purchased
          Notes to you for the accounts of the Purchasers, at the offices of the
          Trustee (at the place  specified  in the Purchase  Agreement)  against

          names as you  request  in writing  not later than 3:00 p.m.,  New York
          Time, on the third full business day prior to the Closing Date, or, if
          no such request is received, in the names of the respective Purchasers
          in the  amounts  agreed  to be  purchased  by  them  pursuant  to this
          Agreement.  The Company shall make the Purchased  Notes  available for
          checking  and  packaging  at the  offices of the Trustee (at the place
          specified  in the Purchase  Agreement)  prior to the Closing Date and,

          not later than 2:00  p.m.,  New York Time,  on the  business  day next
          preceding the Closing Date. If you request that any Purchased Notes be
          issued in a name or names other than that of the Purchaser agreeing to
          purchase  such  Purchased  Notes  hereunder,  the Company shall not be
          obligated to pay any transfer taxes resulting therefrom. The Notes may
          also be represented by a permanent global Note or Notes, registered in
          the  name  of  The  Depository  Trust  Company,   as  depositary  (the
          "Depositary"),  or  a  nominee  of  the  Depositary  (each  such  Note
          represented  by a permanent  global Note being referred to herein as a
          "Book-Entry Note"). Beneficial interests in Book-Entry Notes will only
          be evidenced by, and transfers  thereof will only be effected through,

               4.     Offering by the  Purchasers.  The several  Purchasers
propose to offer the  Purchased  Notes for sale to the public as set forth in
the Prospectus.

               5.     Covenants  of the  Company.  The Company  covenants  and
agrees  with the several  Purchasers that:

               (a) It will  promptly  cause the  Prospectus to be filed with the

               (b) For as long as a prospectus  relating to the Purchased  Notes
        is required to be delivered  under the Act, if any event  relating to or
        affecting  the  Company  or of which the  Company  shall be  advised  in
        writing by the Purchasers  shall occur which, in the Company's  opinion,
        should be set forth in a supplement  or amendment to the  Prospectus  in
        order either to make the Prospectus  comply with the requirements of the
        Act or which would require the making of any change in the Prospectus so
        that as thereafter  delivered to  purchasers  such  Prospectus  will not
        contain  any  untrue  statement  of a  material  fact or omit to state a
        material  fact  necessary in order to make the  statements  therein,  in
        light of the  circumstances  under which they were made, not misleading,
        the Company will promptly  amend or supplement  the Prospectus by either
        (i)  preparing  and  filing  with  the   Commission   supplement(s)   or
        amendment(s)  to the  Prospectus,  or (ii) making an appropriate  filing
        pursuant  to the  Exchange  Act,  which  will  supplement  or amend  the
        Prospectus so that, as supplemented or amended,  the Prospectus when the
        Prospectus is delivered to a purchaser will comply with the Act and will
        not contain any untrue statement of a material fact or omit to state any
        material  fact  necessary in order to make the  statements  therein,  in
        light of the  circumstances  under which they were made, not misleading.
        Prior to any such  filing,  the  Company  shall give oral  notice to the
        Purchasers.

               (c) Not later than 45 days after the end of the  12-month  period
        beginning  at the end of the fiscal  quarter of the Company in which the
        Closing Date occurs,  the Company will make  generally  available to its
        security  holders an  earnings  statement  (which  need not be  audited)
        covering  such  12-month  period  which will satisfy the  provisions  of
        Section 11(a) of the Act.

               (d) The  Company  will  furnish  to you  copies of the  following
        documents,  in each case as soon as  available  after filing and in such
        quantities  as you  reasonably  request (i) the  Registration  Statement
        relating  to  the  Notes  as  originally  filed  and  all  pre-effective
        amendments  thereto  (at  least  one of which  will be  signed  and will
        include all exhibits except those  incorporated by reference to previous
        filings  with the  Commission);  (ii) each  prospectus  relating  to the
        Purchased Notes; and (iii) during the time when a prospectus relating to
        the  Purchased  Notes is required  to be

<PAGE>
                                      -4-

        delivered  under the Act,  all
        post-effective  amendments and supplements to the Registration Statement
        or Prospectus,  respectively  (except supplements relating to securities
        that are not Purchased Notes).

               (e)  The  Company  will  use  its  best  efforts  to  obtain  the
        qualification  of the Purchased Notes for sale and the  determination of
        their eligibility for investment under the laws of such jurisdictions as
        you designate and will continue such qualifications in effect so long as
        required for the distribution, provided, however, that the Company shall
        not be  required  to  qualify  as a foreign  corporation  or to file any
        consent to service of process under the laws of any  jurisdiction  or to
        comply  with any other  requirements  deemed by the Company to be unduly
        burdensome.

               (f) During the period of five years after the Closing  Date,  the
        Company  will  furnish to you,  and upon  request,  to each of the other
        Purchasers:  (i) as soon as  practicable  after  the end of each  fiscal
        year, a copy of its annual report to shareholders for such year, (ii) as
        soon as available,  a copy of each report or definitive  proxy statement
        of the  Company  filed with the  Commission  under the  Exchange  Act or
        mailed  to  shareholders,  and  (iii)  from  time to  time,  such  other
        information concerning the Company as you may reasonably request.

               (g) The Company will pay all expenses incident to the performance
        of  its  obligations  under  this  Agreement,  and  will  reimburse  the
        Purchasers  for any  expenses  (including  Blue Sky  fees not  exceeding
        $6,000 and disbursements of counsel) incurred by them in connection with
        qualification of the Purchased Notes for sale and determination of their
        eligibility for investment  under the laws of such  jurisdictions as you
        designate and the printing of memoranda relating thereto, for any filing
        fees  charged  by  investment  rating  agencies  for the  rating  of the
        Purchased  Notes,  for any expenses  incurred in connection with listing
        the Purchased Notes on a national  securities  exchange and for expenses
        incurred in distributing prospectuses to the Purchasers,  except that if
        this  Agreement  is  terminated  by the  Purchasers  under  Section 6(c)
        hereof,  the Company shall not be obligated to reimburse the  Purchasers
        for any of the foregoing expenses.

               (h) The  Company  will not  offer or sell any of its  other  debt
        securities which are substantially  similar to the Purchased Notes prior
        to ten  business  days after the Closing Date without the consent of the
        Purchasers.

          obligations  of the several  Purchasers  to  purchase  and pay for the
          Purchased Notes will be subject to the accuracy of the representations

               (1) any unaudited consolidated financial statements  incorporated
               by reference in the Registration  Statement do not comply in form
               in all material respects with the applicable  requirements of the
               Act and the 33 Act Rules and Regulations and the Exchange Act and
               the   Exchange  Act  Rules  and   Regulations   or  any  material

                      (iii) Certain  specified  procedures  have been applied to

               of the  Company)  set forth or  incorporated  by reference in the
               Registration Statement and that such procedures have not revealed

               general accounting records of the Company, except as described in
               such letter.

               (b) Prior to the  Closing  Date,  no stop  order  suspending  the
        effectiveness of the  Registration  Statement shall have been issued and

        particularly the business or properties of the
        Company  which,  in  the  judgment  of a  majority  in  interest  of the
        Purchasers  including you,  materially impairs the investment quality of

        moratorium  shall not have  been  declared  either by New York  State or

        escalation of major  hostilities  in which the United States is involved
        or other substantial  national or international  calamity or crisis, the
        effect of which on the financial markets of the United States is such as
        to make it, in your  judgment,  impracticable  to market  the  Purchased
        Notes.

               (d) You shall have  received an opinion,  dated the Closing Date,
        of a counsel for the Company to the effect that:

                      (i) The Company, BGE and Constellation  Enterprises,  Inc.
               (CEI) have been duly  incorporated  and are  validly  existing as
               corporations  in good  standing  under  the laws of the  State of
               Maryland,  with power and authority  (corporate and other) to own
               their   respective   properties  and  conduct  their   respective
               businesses as described in the  Prospectus;  the Company owns all
               of the outstanding shares of common stock of BGE and CEI; and the
               Company is duly qualified to do business as a foreign corporation
               in good standing in all other  jurisdictions in which the conduct
               of its business or the ownership of its properties  requires such
               qualification  and the failure to do so would have a material and
               adverse impact on its financial condition;

                      (ii) The Indenture has been duly authorized,  executed and
               delivered  by the  Company  and is a  valid  instrument,  legally
               binding on the Company and  enforceable  in  accordance  with its
               terms, except as limited by bankruptcy, insolvency, or other laws
               affecting the  enforcement  of  creditors'  rights and by general
               principles of equity;

                      (iii) The  issuance and sale of the  Purchased  Notes have
               been duly  authorized  by all necessary  corporate  action of the
               Company. The Purchased Notes being delivered to the Purchasers at
               the Closing  (assuming that they have been duly  authenticated by
               the Trustee or a duly designated  Authentication  Agent under the
               Indenture, which fact counsel need not verify by an inspection of

                                      -8-

               the Purchased Notes), have been duly issued and constitute legal,
               valid,  and binding  obligations  of the Company  enforceable  in
               accordance  with their  terms,  and are  entitled to the benefits
               provided  by the  Indenture  except  as  such  enforceability  or
               entitlement  may be limited by bankruptcy,  insolvency,  or other
               laws  affecting  the  enforcement  of  creditors'  rights  and by
               general principles of equity;

                      (iv) The Registration Statement has become effective under
               the Act and, (a) to the best of such counsel's knowledge, no stop
               order suspending the effectiveness of the Registration  Statement
               has been issued and no  proceedings  for that  purpose  have been
               instituted or are pending or contemplated  under the Act; (b) the
               Registration  Statement  (as  of  its  effective  date)  and  the
               Prospectus  (as  of  the  date  of  the  Closing  Date)  and  any
               amendments or supplements  thereto, as of their respective dates,
               appeared to comply as to form in all material  respects  with the
               requirements  of Form S-3  under the Act and the 33 Act Rules and
               Regulations  and the Trust Indenture Act; (c) such counsel has no
               reason to believe that either the  Registration  Statement or the
               Prospectus,  or any  such  amendment  or  supplement,  as of such
               respective  dates,  contained any untrue  statement of a material
               fact or omitted to state any material  fact required to be stated
               therein  or   necessary  to  make  the   statement   therein  not
               misleading;  (d) the descriptions in the  Registration  Statement
               and Prospectus of statutes,  legal and  governmental  proceedings
               and contracts and other documents are accurate and fairly present
               the information  required to be shown;  (e) and such counsel does
               not know of any legal or governmental  proceedings required to be
               described in the Prospectus  which are not described as required,
               or of any  contracts or  documents of a character  required to be
               described in the  Registration  Statement or  Prospectus or to be
               filed as exhibits  to the  Registration  Statement  which are not
               described or filed as  required;  it being  understood  that such
               counsel, in addressing the matters covered in this paragraph (iv)
               need express no opinion as to the  financial  statements or other
               financial   and   statistical   information   contained   in  the
               Registration  Statement or the Prospectus or incorporated therein
               or  attached  as an  exhibit  thereto or as to the  Statement  of
               Eligibility  and  Qualification  on Form T-l of the Trustee under
               the Indenture.

                      (v)  Counsel  knows  of  no  approval  of  any  regulatory
               authority  which is  legally  required  for the  valid  offering,
               issuance, sale and delivery of the Purchased Notes by the Company
               under this Agreement (except that such opinion need not pass upon
               the requirements of state securities acts);

                                      -9-

                      (vi) To the best of such  counsel's  knowledge and belief,
               the  consummation  of  the  transactions   contemplated  in  this
               Agreement and the compliance by the Company with all the terms of
               the  Indenture  did not and will not result in a breach of any of
               the terms and provisions  of, or constitute a default under,  the
               Company's  Charter or By-Laws or any indenture,  mortgage or deed
               of trust or other agreement or instrument to which the Company is
               a party;

                      (vii) Each of this Agreement and, the Interest Calculation
               Agency Agreement has been duly authorized, executed and delivered

                      (viii) The Indenture is duly qualified under the Trust
              Indenture Act;

                      (ix) The  issuance,  sale and  delivery  of the  Purchased
               Notes as  contemplated  by this  Agreement are not subject to the
               approval of the  Securities  and  Exchange  Commission  under the
               provisions of the Public Utility Holding Company Act of 1935 (the
               "1935 Act"); and

                      (x) The Notes and  Indenture  conform as to legal  matters
               with the statements concerning them in the Registration Statement
               and Prospectus  under the caption  "DESCRIPTION  OF NOTES" and on
               the cover page of the Prospectus.

               (e) The Agents shall have  received from Cahill Gordon & Reindel,
counsel for the Agents,  an opinion dated the Closing Date,  with respect to the
matters  referred to in paragraph 6(d)  subheadings  (ii),  (iii),  (iv)b,  (v),
(vii),(viii),  and (x) and such other  matters as the  Agents  shall  reasonably
request and the Company shall have  furnished to such counsel such  documents as
they request for the purpose of enabling them to pass on such matters.

                      In rendering such opinion,  Cahill Gordon & Reindel may
rely, as to the  incorporation of the Company, all other matters governed by
the laws of the State of Maryland and the applicability  of the 1935 Act , upon
the  opinion  of Counsel  for the  Company referred to above.

                      In addition,  such  counsel  shall state that such
counsel has  participated  in  conferences
with officers, counsel and other representatives of the Company, representatives
of the independent public accountants for the Company and representatives of the
Purchasers  at  which  the  contents  of  the  Registration

<PAGE>
                                      -10-

Statement  and  the
Prospectus and related matters were discussed; and, although such counsel is not
passing upon and does not assume  responsibility for the accuracy,  completeness
or  fairness of the  statements  contained  in the  Registration  Statement  and
Prospectus  (except as to the  matters  referred  to in their  opinion  rendered
pursuant to subheading (x) above), on the basis of the foregoing  (relying as to
materiality  to a large extent upon the opinions of officers,  counsel and other
representatives  of the  Company),  no facts have come to the  attention of such
counsel  which  lead such  counsel  to  believe  that  either  the  Registration
Statement (as of its effective  date) or the  Prospectus (as of the date of this
Agreement),  and any subsequent  amendments or supplements  thereto, as of their
respective dates, contained an untrue statement of a material fact or omitted to
state a material  fact  required to be stated  therein or necessary to make such
statements  therein not misleading (it being  understood  that such counsel need
make no comment with respect to the financial statements and other financial and
statistical  data  included  in the  Registration  Statement  or  Prospectus  or
incorporated  therein or as to the Statement of Eligibility and Qualification on
Form T-l of the Trustee under the Indenture).

               (f) You shall have received a certificate  of the Chairman of the
        Board,  President  or any Vice  President  and a principal  financial or
        accounting officer of the Company, dated the Closing Date, in which such
        officers shall state, to the best of their  knowledge  after  reasonable
        investigation,  and  relying on  opinions  of counsel to the extent that
        legal matters are involved,  that the  representations and warranties of
        the  Company in this  Agreement  are true and  correct  in all  material
        respects,  that  the  Company  has  complied  with  all  agreements  and
        satisfied all  conditions on its part to be performed or satisfied at or
        prior  to  the  Closing  Date,   that  no  stop  order   suspending  the
        effectiveness  of the  Registration  Statement  has been  issued  and no
        proceedings for that purpose have been instituted or are contemplated by
        the  Commission,  and that,  subsequent  to the date of the most  recent
        financial  statements  set forth or  incorporated  by  reference  in the
        Prospectus,  there has been no material  adverse change in the financial
        position or in the financial  results of operation of the Company except
        as set forth or contemplated in the Prospectus.

               (g) The Company  will furnish you with such  conformed  copies of
        such  opinions,  certificates,  letters and documents as you  reasonably
        request.

               In case any such condition  shall not have been  satisfied,  this
Agreement  may be terminated by you upon notice in writing or by telecopy to the
Company  without  liability  or  obligation  on the part of the  Company  or any
Purchaser, except as set forth in Section 10 hereof.

               7.     Conditions of the  Obligations  of the Company.  The
obligations  of the Company to sell and
deliver the Purchased Notes are subject to the following condition precedent:

<PAGE>
                                      -11-

                      Prior to the Closing  Date, no stop order  suspending  the
        effectiveness of the  Registration  Statement shall have been issued and
        no  proceedings  for that purpose shall have been  instituted or, to the
        knowledge  of  the  Company  or  you,  shall  be   contemplated  by  the
        Commission.

               If this condition shall not have been satisfied, then the Company
        shall be  entitled,  by notice in  writing  or by  telecopy  to you,  to
        terminate  this  Agreement  without  any  liability  on the  part of the
        Company or any Purchaser, except as set forth in Section 10 hereof.

               8.     Indemnification.
                      ---------------

               (a) The Company will  indemnify and hold harmless each  Purchaser
        and each person,  if any, who controls any Purchaser  within the meaning
        of the Act or  Exchange  Act  against  any  losses,  claims,  damages or
        liabilities,   joint  or  several,  to  which  such  Purchaser  or  such
        controlling  person  may  become  subject,  under the Act or  otherwise,
        insofar as such losses,  claims,  damages or liabilities  (or actions in
        respect  thereof) arise out of or are based upon any untrue statement or
        alleged  untrue   statement  of  any  material  fact  contained  in  the
        Registration  Statement or the  Prospectus,  or any related  preliminary
        prospectus  or arise out of or are based  upon the  omission  or alleged
        omission to state therein a material fact required to be stated  therein
        or necessary to make the  statements  therein not  misleading;  and will
        reimburse each Purchaser and each such controlling  person for any legal
        or  other  expenses  reasonably  incurred  by  such  Purchaser  or  such
        controlling  person in connection  with  investigating  or defending any
        such loss, claim, damage, liability or action;  provided,  however, that
        the Company will not be liable to such Purchaser or  controlling  person
        in any such case to the  extent  that any such  loss,  claim,  damage or
        liability  arises out of or is based upon an untrue statement or alleged
        untrue  statement  or  omission  or  alleged  omission  made in any such
        documents in reliance  upon and in conformity  with written  information
        furnished to the Company by such  Purchaser or such  controlling  person
        specifically  for  use  therein  unless  such  loss,  claim,  damage  or
        liability  arises  out of the  offer  or  sale  of the  Purchased  Notes
        occurring  after such Purchaser or  controlling  person has notified the
        Company  in  writing  that  such  information  should  no longer be used
        therein.  This indemnity  agreement will be in addition to any liability
        which the Company may otherwise have.

               (b) Each  Purchaser will indemnify and hold harmless the Company,
        each  of its  directors,  each  of its  officers  who  have  signed  the
        Registration Statement and each person, if any, who controls the Company
        within the meaning of the Act or the Exchange  Act,  against any losses,
        claims,  damages  or  liabilities  to  which  the  Company  or any  such
        director,

<PAGE>
                                      -12-

        officer or controlling  person may become subject,  under the
        Act,  or  otherwise,   insofar  as  such  losses,   claims,  damages  or
        liabilities  (or actions in respect  thereof)  arise out of or are based
        upon any untrue  statement or alleged  untrue  statement of any material
        fact contained in the Registration  Statement or the Prospectus,  or any
        related  preliminary  prospectus  or arise out of or are based  upon the
        omission  or the  alleged  omission  to state  therein a  material  fact
        required  to be  stated  therein  or  necessary  to make the  statements
        therein  not  misleading,  in each case to the  extent,  but only to the
        extent,  that such  untrue  statement  or alleged  untrue  statement  or
        omission or alleged omission was made in reliance upon and in conformity
        with  written  information  furnished  to the Company by such  Purchaser
        specifically  for use  therein;  and will  reimburse  any legal or other
        expenses  reasonably  incurred  by the  Company  or any  such  director,
        officer  or  controlling  person in  connection  with  investigating  or
        defending  any such loss,  claim,  damage,  liability  or action as such
        expenses are incurred;  provided,  however, that such Purchaser will not
        be liable to the Company,  or any such director,  officer or controlling
        person in any such case to the extent that any such loss, claim,  damage
        or  liability  arises  out of the  offer  or  sale  of  Purchased  Notes
        occurring  after such Purchaser has notified the Company in writing that
        such  information  should  no  longer be used  therein.  This  indemnity
        agreement will be in addition to any liability  which such Purchaser may
        otherwise have.

               (c) Promptly  after  receipt by an  indemnified  party under this
        Section of notice of the  commencement of any action,  such  indemnified
        party  will,  if a claim in respect  thereof is to be made  against  the
        indemnifying  party  under (a) and (b) above,  notify  the  indemnifying
        party of the  commencement  thereof;  but the  omission so to notify the
        indemnifying  party will not relieve it from any liability  which it may
        have to any indemnified party otherwise than under this Section. In case
        any such  action  is  brought  against  any  indemnified  party,  and it
        notifies  the  indemnifying  party  of  the  commencement  thereof,  the
        indemnifying  party will be entitled to participate  therein and, to the
        extent  that it may  wish,  jointly  with any other  indemnifying  party
        similarly  notified,   to  assume  the  defense  thereof,  with  counsel
        satisfactory to such indemnified party (who may, with the consent of the
        indemnified  party, be counsel to the indemnifying  party) and who shall
        not be counsel  to any other  indemnified  party who may have  interests
        conflicting with those of such indemnified  party, and after notice from
        the indemnifying  party to such indemnified  party of its election so to
        assume the defense thereof, the indemnifying party will not be liable to
        such  indemnified  party  under  this  Section  for any  legal  or other
        expenses  subsequently  incurred by such indemnified party in connection
        with the defense thereof other than reasonable costs of investigation.

<PAGE>
                                      -13-

               (d)  If   recovery   is  not   available   under  the   foregoing
        indemnification provisions of this Section, for any reason other than as
        specified therein,  the parties entitled to indemnification by the terms
        thereof shall be entitled to  contribution  to liabilities and expenses,
        except to the extent that  contribution  is not permitted  under Section
        11(f) of the Act. In determining the amount of contribution to which the
        respective parties are entitled,  there shall be considered the relative
        benefits received by each party from the offering of the Purchased Notes
        (taking  into  account  the  portion  of the  proceeds  of the  offering
        realized  by  each),  the  parties'  relative  knowledge  and  access to
        information  concerning  the matter with  respect to which the claim was
        asserted,  the  opportunity  to correct  and prevent  any  statement  or
        omission, and any other equitable  considerations  appropriate under the
        circumstances.  The  Company  and the  Purchasers  and such  controlling
        persons  agree  that it would  not be  equitable  if the  amount of such
        contribution  were determined by pro rata or per capita allocation (even
        if the  Purchasers  and such  controlling  persons  were  treated as one
        entity  for  such  purpose).  Notwithstanding  the  provisions  of  this
        subsection (d), no Purchaser or controlling  person shall be required to
        make  contribution  hereunder  which in the aggregate  exceeds the total
        public offering price of the Purchased Notes, purchased by the Purchaser
        under this  Agreement,  less the  aggregate  amount of any damages which
        such Purchaser or such controlling person has otherwise been required to
        pay in respect of the same claim or any substantially similar claim. The
        Purchasers' obligations to contribute are several in proportion to their
        respective underwriting obligations and are not joint.

               9. Default of Purchasers.  If any Purchaser or Purchasers default
in their  obligations to purchase  Purchased  Notes  hereunder and the aggregate
principal  amount  of  Purchased  Notes  which  such  defaulting   Purchaser  or
Purchasers  agreed  but failed to  purchase  is 10% of the  principal  amount of
Purchased Notes or less, you may make  arrangements  satisfactory to the Company
for the purchase of such Purchased Notes by other persons,  including any of the
Purchasers,  but if no such  arrangements  are  made  by the  Closing  Date  the
non-defaulting  Purchasers shall be obligated severally,  in proportion to their
respective  commitments  hereunder,  to purchase the Purchased  Notes which such
defaulting  Purchasers  agreed  but  failed to  purchase.  If any  Purchaser  or
Purchasers so default and the aggregate principal amount of Purchased Notes with
respect  to  which  such  default  or  defaults  occur is more  than  the  above
percentage and arrangements satisfactory to you and the Company for the purchase
of such Purchased  Notes by other persons are not made within  thirty-six  hours
after such default,  this Agreement will terminate without liability on the part
of any  non-defaulting  Purchaser or the Company,  except as provided in Section
10. In the event that any Purchaser or Purchasers default in their


<PAGE>
                                      -14-
obligation to
purchase Purchased Notes hereunder, the Company may, by prompt written notice to
the  non-defaulting  Purchasers,  postpone  the Closing Date for a period of not
more than seven  full  business  days in order to effect  whatever  changes  may
thereby be made necessary in the Registration  Statement or the Prospectus or in
any other  documents,  and the Company will promptly file any  amendments to the
Registration  Statement or supplements  to the  Prospectus  which may thereby be
made necessary.  As used in this Agreement,  the term  "Purchaser"  includes any
person  substituted  for a Purchaser  under this  Section.  Nothing  herein will
relieve a defaulting Purchaser from liability for its default.

               10.  Survival of Certain  Representations  and  Obligations.  The
respective  indemnities,  agreements,  representations,  warranties,  and  other
statements  of the Company or its  officers  and of the several  Purchasers  set
forth in or made  pursuant  to this  Agreement  will  remain  in full  force and
effect, regardless of any investigation, or statement as to the results thereof,
made by or on behalf of any  Purchaser  or the Company or any of its officers or
directors or any controlling  person,  and will survive  delivery of and payment
for the Purchased Notes. If this Agreement is terminated  pursuant to Section 6,
7 or 9 or if  for  any  reason  the  purchase  of  the  Purchased  Notes  by the
Purchasers  is not  consummated,  the Company shall remain  responsible  for the
expenses to be paid or  reimbursed  by it pursuant to Section 5(g). In addition,
in such event the  respective  obligations  of the  Company  and the  Purchasers
pursuant to Section 8 shall remain in effect;  provided,  however, that you will
use your best efforts to promptly  notify each other  Purchaser  and each dealer
and  prospective  customer  to whom  you have  delivered  a  Prospectus  for the
Purchased  Notes by telephone or telegraph,  confirmed by letter in either case,
of  such  termination  or  failure  to  consummate,  including  in  such  notice
instructions  regarding  the continued use of the  Registration  Statement,  the
Prospectus,  or any amendment or supplement  thereto, or any related preliminary
prospectus.

               11.  Notices.  All  communications  hereunder will be in writing,
and, if sent to the Purchasers  will be delivered or telecopied and confirmed to
the  address  furnished  in  writing  for the  purpose  of  such  communications
hereunder,  or, if sent to the  Company,  will be delivered  or  telecopied  and
confirmed to it,  attention of  Treasurer  at 250 W. Pratt  Street,  20th Floor,
Baltimore, Maryland 21201, telecopier (410) 783-3610;

               12. Successors. This Purchase Agreement will inure to the benefit
of and be binding upon the parties  hereto and their  respective  successors and
the officers and directors and controlling persons referred to in Section 8, and
no other person will have any right or obligation hereunder.

               13.    Construction.  This  Purchase  Agreement  shall be
governed by and  construed  in  accordance with the laws of the State of
Maryland.

               14.    Counterparts.  This  Agreement  may be  executed  in one
or more  counterparts  and it is not necessary that the signatures of all
parties appear on the same counterpart,  but such counterparts  together shall
constitute but one and the same agreement.

                               FROM DATE OF ISSUE

                      INTEREST CALCULATION AGENCY AGREEMENT


        THIS AGREEMENT dated as of May_____,  2000 between  Constellation Energy
        Group,  Inc.  (hereinafter  called the  "Issuer"),  having its principal
        office at 250 W. Pratt Street,  20th Floor,  Baltimore,  Maryland 21201,
        and The Bank of New York,  a New York banking  corporation  (hereinafter
        sometimes  called the  "Calculation  Agent or Paying  Agent" which terms
        shall,   unless  the  context  shall  otherwise  require,   include  its
        successors and assigns),  having its principal corporate trust office at
        101  Barclay  Street,  Floor 21 West,  New York,  New York  10286  Attn:
        Corporate Trust Administration.


                             Recitals of the Issuer

         The  Issuer  proposes  to issue  from  time to time up to  $500,000,000
aggregate principal amount of Medium-Term Notes, Series B (the "Notes") under an
indenture dated as of March 24, 1999 (the  "Indenture"),  between the Issuer and
The Bank of New York (the "Trustee"), as Trustee. Capitalized terms used in this
Agreement and not otherwise defined herein are used as defined in the Indenture.
Certain  of the  Notes  may bear  interest  at a

<PAGE>

floating  rate  determined  by reference to an interest rate formula (the
"Floating Rate Notes") and the Issuer desires  to  engage  the  Calculation
Agent  to  perform  certain  services  in connection therewith.

                  NOW IT IS HEREBY AGREED THAT:

        1. The Issuer hereby appoints The Bank of New York as Calculation  Agent
for the Floating Rate Notes, upon the terms and subject to the conditions herein
mentioned,  and The  Bank of New  York  hereby  accepts  such  appointment.  The
Calculation  Agent  shall  act as an  agent of the  Issuer  for the  purpose  of
determining the interest rate or rates of the Floating Rate Notes.

        2. The Issuer agrees to deliver to the Calculation  Agent,  prior to the
issuance of any Floating Rate Notes, copies of the proposed forms of such Notes,
including  copies of all terms and conditions  relating to the  determination of
the interest rate thereunder.  The Issuer shall not issue any Floating Rate Note
prior  to  the  receipt  of  confirmation  from  the  Calculation  Agent  of its
acceptance  of the  proposed  form of such Note.  The  Calculation  Agent hereby
acknowledges  its  acceptance  of  the  proposed  form  of  Floating  Rate  Note
previously delivered to it.

                                       2

<PAGE>

        3. The Issuer shall notify the Calculation  Agent of the issuance of any
Floating  Rate Notes  prior to the  issuance  thereof  and,  at the time of such
issuance,  shall deliver to the Calculation Agent the information required to be
provided by the Company for the  calculation  of the  applicable  interest rates
thereunder.  The Calculation Agent shall calculate the applicable interest rates
for  Floating  Rate  Notes in  accordance  with the  terms  of such  Notes,  the
Indenture and the provisions of this Agreement.

        4. Promptly  following the  determination of each change to the interest
rate applicable to any Floating Rate Note, the  Calculation  Agent will cause to
be  forwarded  to the  Issuer,  the  Trustee  and  the  principal  Paying  Agent
information  regarding  the interest  rate then in effect for such Floating Rate
Note.

        5. The Issuer  will pay such  compensation  as shall be agreed upon with
the Calculation Agent and the expenses,  including  reasonable  counsel fees and
expenses,  incurred  by the  Calculation  Agent in  connection  with its  duties
hereunder, upon receipt of such invoices as the Issuer shall reasonably require.

        6.  Notwithstanding  any  satisfaction  or discharge of the Notes or the
Indenture,  the Issuer will indemnify the Calculation  Agent against any losses,
liabilities,  costs, claims, actions or demands which it may incur or sustain or
which may be made against it in connection  with its appointment or the

                                       3

<PAGE>

exercise of its powers and duties  hereunder  as well as the  reasonable  costs,
including  the expenses and fees of counsel in  defending  any claim,  action or
demand,  except such as may result from the negligence or willful  misconduct of
the Calculation Agent or any of its employees. The Calculation Agent shall incur
no liability and shall be indemnified and held harmless by the Issuer for, or in
respect  of,  any  actions  taken or  suffered  to be taken in good faith by the
Calculation Agent in reliance upon written instructions from the Issuer. In case
any action is brought  against the  Calculation  Agent with respect to which the
Calculation  Agent intends to seek  indemnification  from the Issuer pursuant to
this paragraph 6, the Calculation Agent will notify the Issuer in writing of the
commencement thereof, and the Issuer will be entitled to participate therein and
to assume the defense  thereof,  with counsel  satisfactory  to the  Calculation
Agent; provided, however, that if the defendants in any such action include both
the  Issuer  and the  Calculation  Agent and the  Calculation  Agent  shall have
reasonably  concluded,  after  consultation  with legal counsel of its choosing,
that there may be legal  defenses  available to it which are  different  from or
additional to those available to the Issuer,  the  Calculation  Agent shall have
the right to select separate counsel to assert such legal defenses and otherwise
to participate in the defense of such action on behalf of the Calculation Agent,
and in such event the Issuer will  indemnify the  Calculation  Agent against the
reasonable compensation and expenses and disbursements of such separate counsel.

                                       4

<PAGE>

          7. The Calculation  Agent may consult with counsel of its ow selection
(and notify the Issuer of such  consultation)  and the advice of such counsel or
any opinion of counsel shall be full and complete  authorization  and protection
in respect of any action  taken,  suffered  or omitted by it  hereunder  in good
faith and in reliance thereon.

          8. The Calculation Agent accepts its obligations herein set forth upon
the terms and conditions  hereof,  including the following,  to all of which the
Issuer agrees:

                (i) in acting under this  Agreement and in  connection  with the
 Notes,  the  Calculation  Agent,  acting as agent for the Issuer,  does not
assume any obligation  towards,  or any  relationship of agency or trust for o

               (ii) unless herein otherwise  specifically  provided,  any order,
certificate,  notice,  request or  communication  from the Issuer  made or given
under any  provision  of this  Agreement  shall be  sufficient  if signed by any
person whom the Calculation  Agent  reasonably  believes to be a duly authorized
officer or attorney-in-fact of the Issuer;

              (iii) the  Calculation  Agent shall be  obligated  to perform only
such  duties  as are set  forth  specifically  herein  and any duties

<PAGE>

                           (iv) the  Calculation  Agent shall be  protected  and
                  shall incur no liability for or in respect of any action taken
                  or omitted to be taken or  anything  suffered in good faith by
                  it in reliance  upon  anything  contained  in a Floating  Rate
                  Note, the Indenture or any  information  supplied to it by the
                  Issuer pursuant to this  Agreement,  including the information
                  to be supplied pursuant to paragraph 3 above;

                           (v) the Calculation Agent,  whether acting for itself
                  or in any other  capacity,  may become the owner or pledgee of
                  Notes with the same rights as it would have had if it were not
                  acting hereunder as Calculation Agent; and

                           (vi) the  Calculation  Agent shall incur no liability
                  hereunder   except  for  loss   sustained  by  reason  of  its
                  negligence or willful misconduct or bad faith.

                  9. (a) The Issuer  agrees to notify the  Calculation  Agent at
least 3 business  days prior to the issuance of any  Floating  Rate Note with an
interest rate to be determined  by reference to London  interbank  offered rates
(LIBOR) or any other formula that would require the Calculation  Agent to select
banks or other financial  institutions  (the "Reference  Banks") for purposes of
quoting rates.  The Calculation  Agent shall not be responsible to the Issuer or
any third party for any failure of the  Reference  Banks to fulfill their duties
or meet their  obligations as Reference  Banks or as a result of the Calculation

Agent having acted (except in the event of negligence or willful  misconduct) on
any  quotation  or  other   information   given  by  any  Reference  Bank  which
subsequently may be found to be incorrect.

                           (b)      Except as provided  below,  the  Calculation
Agent may at any time resign as  Calculation  Agent by giving  written notice to
the Issuer and the Trustee of such intention on its part, specifying the date on
which its desired resignation shall become effective,  provided that such notice
shall be given not less than 60 days prior to the said effective date unless the
Issuer and the Trustee otherwise agree in writing. Except as provided below, the
Calculation  Agent may be removed by the  filing  with it and the  Trustee of an
instrument in writing signed by the Issuer  specifying such removal and the date
when it shall become effective (such effective date being at least 15 days after
said filing). Any such resignation or removal shall take effect upon:

                           (i)      the appointment by the Issuer as hereinafte
provided of a successor Calculation Agent; and
                           (ii)     the acceptance of such appointment by such
successor Calculation Agent;

provided,  however,  that in the event the Calculation  Agent has given not less
than 60 days' prior notice of its desired  resignation,  and during such 60 days
there  has  not  been  acceptance  by  a  successor  Calculation  Agent  of  its
appointment as successor  Calculation  Agent, the Calculation Agent so resigning
may  petition  any court of  competent  jurisdiction  for the  appointment  of a
successor  Calculation  Agent.  The  Issuer

                                       7

<PAGE>

covenants  that it  shall  appoint  a  successor  Calculation  Agent  as soon as
practicable  after  receipt of any  notice of  resignation  hereunder.  Upon its
resignation or removal becoming effective,  the retiring Calculation Agent shall
be entitled  to the payment of its  compensation  and the  reimbursement  of all
reasonable expenses (including reasonable counsel fees and expenses) incurred by
such retiring Calculation Agent pursuant to paragraph 5 hereof.

                           (c)      If at any time the  Calculation  Agent shall
esign or be removed,  or shall  become  incapable of acting or shall be adjudged
bankrupt or insolvent,  or  liquidated  or dissolved,  or an order is made or an
effective  resolution  is passed  to wind up the  Calculation  Agent,  or if the
Calculation  Agent shall file a  voluntary  petition  in  bankruptcy  or make an
assignment for the benefit of its creditors, or shall consent to the appointment
of a receiver, administrator or other similar official of all or any substantial
part of its property, or shall admit in writing its inability to pay or meet its
debts as they mature, or if a receiver,  administrator or other similar official
of the Calculation Agent or of all or any substantial part of its property shall
be  appointed,  or if any  order of any court  shall be  entered  approving  any
petition filed by or against the  Calculation  Agent under the provisions of any
applicable  bankruptcy  or insolvency  law, or if any public  officer shall take
charge or control of the  Calculation  Agent or its  property or affairs for the
purpose  of  rehabilitation,  conservation  or  liquidation,  then  a  successor
Calculation  Agent shall be

                                       8

<PAGE>

appointed by the Issuer by an  instrument  in writing  filed with the  successor
Calculation  Agent and the  Trustee.  Upon the  appointment  as  aforesaid  of a
successor Calculation Agent and acceptance by the latter of such appointment the
former Calculation Agent shall cease to be Calculation Agent hereunder.

                           (d)      Any successor  Calculation Agent appointed
hereunder  shall  execute  and  deliver to its  predecessor,  the Issuer and the
Trustee and instrument accepting such appointment hereunder,  and thereupon such
successor Calculation Agent, without any further act, deed or conveyance,  shall
become vested with all the authority,  rights,  powers,  immunities,  duties and
obligations of such  predecessor  with like effect as if originally named as the
Calculation  Agent  hereunder,  and  such  predecessor,   upon  payment  of  its
reasonable compensation,  charges and disbursements then unpaid, shall thereupon
become  obliged to transfer and deliver,  and such successor  Calculation  Agent
shall be entitled to receive,  copies of any relevant records maintained by such
predecessor Calculation Agent.

                           (e)      Any  corporation  into which the
Calculation  Agent may be merged or converted or any corporation  with which the
Calculation  Agent may be  consolidated  or any  corporation  resulting from any
merger,  conversion or consolidation  to which the Calculation  Agent shall be a
party  shall,  to the extent  permitted  by  applicable  law,  be the  successor
Calculation  Agent under this  Agreement  without the execution or filing of any
paper or any further act on the part of any of the parties hereto.

Notice of any such merger,  conversion or consolidation shall forthwith be given
to the Issuer and the Trustee.

                           (f)      The provisions of paragraph 6 hereof shall
survive any resignation or removal hereunder.

                  10.  Any  notice  required  to be  given  hereunder  shall  be
delivered in person,  by overnight mail or sent by facsimile or  communicated by

dispatched within two business days by letter or facsimile),  in the case of the
Issuer,  to it at the  address  set  forth  in the  heading  of this  Agreement,
Attention: Treasurer; in the case of the Trustee or the Calculation Agent, to it
at the address set forth in the heading of this  Agreement;  or, in any case, to
any other  address of which the party  receiving  notice shall have notified the

                  11.      This  Agreement may be amended only by a writing duly

                        CONSTELLATION ENERGY GROUP, INC.

                           MEDIUM-TERM NOTE, SERIES B
                                  (FIXED RATE)

               This Note is one of a duly  authorized  issue of debt  securities
(the  "Securities")  of the Company,  of a series  designated as its Medium-Term
Notes,  Series B (herein  called the  "Notes"),  limited  (except  as  otherwise
provided in the Indenture) in aggregate principal amount to $500,000,000, issued
and to be issued  under  the  Indenture,  to which  Indenture  and all  relevant
indentures  supplemental thereto reference is hereby made for a statement of the
respective rights, obligations, duties and immunities thereunder of the Company,
the Trustee, the Bank and the Securityholders and the terms upon which the Notes
are, and are to be,  authenticated and delivered.  The Securities,  of which the
Notes constitute a series, may be issued in one or more series,  which different
series  may be issued in  various  aggregate  principal  amounts,  may mature at
different  times,  may bear  interest  at  different  rates,  may be  subject to
different  covenants  and Events of  Default  and may  otherwise  vary as in the
Indenture  provided.  All capitalized  terms not otherwise  defined herein shall
have the definitions assigned to them in the Indenture.

               This  Note may not be  redeemed  by the  Company  prior to Stated
Maturity unless otherwise set forth on the face hereof.  Notwithstanding Section
4.03 of the Indenture,  pursuant to Section 4.01 thereof, and if so indicated on
the face of this Note, this Note may be redeemed at the option of the Company on
any date on or after the date set  forth on the face  hereof in whole or in part
in increments of $1,000,  at a redemption price or prices designated on the face
hereof to be redeemed  together with interest  thereon payable to the date fixed
for redemption.  This Note may be so redeemed in whole or in part whether or not
other Notes of the same series are redeemed.

               Notice of  redemption by the Company will be given by the Company
by mail to holders of the Notes to be  redeemed,  not less than 30 nor more than
60  days  prior  to the  date  fixed  for  redemption,  all as  provided  in the
Indenture.  The Bank may carry out the  responsibilities  to be performed by the
Trustee required by Article Four of the Indenture.

        The Company is not required to  repurchase  Notes from holders  prior to
Stated Maturity unless  otherwise set forth on the face hereof.  If so indicated
on the face hereof, this Note may be repurchased by the Company at the option of
the holder on the dates and at the  prices  designated  thereon,  in whole or in
part in increments of $1,000,  together with interest  payable to the repurchase
date. For book-entry notes, unless otherwise specified on the face of this Note,
holders  must deliver  written  notice to the Bank at least 30, but no more than
60, days prior to the date

                                      -4-

<PAGE>

     of  repurchase,  but no later than 5:00 p.m. New York City time on the last
     day for giving notice. The written notice must specify the principal amount
     to be repurchased  and must be signed by a duly  authorized  officer of the
     Depositary participant (signature guaranteed). For definitive notes, unless
     otherwise  specified on the face of this Note,  holders  must  complete the
     "Option to Elect  Repayment"  on the reverse of this Note and then  deliver
     this Note to the Bank at least 30,  but no more than 45,  days prior to the
     date of  repurchase,  but no later than 5:00 p.m. New York City time on the
     last day for giving notice. All notices are irrevocable.

               In the event of  redemption  or  repurchase  of this Note in part
only,  a new Note or Notes of this  series,  having  the same  Stated  Maturity,
optional redemption or repurchase provisions,  Interest Rate and other terms and
provisions of this Note, in authorized  denominations in an aggregate  principal
amount equal to the unredeemed  portion hereof will be issued in the name of the
holder hereof upon the surrender hereof.

[Remarketing provisions, if any, to be included here]

               The Notes will not be subject to conversion,  amortization or any
sinking fund.

               As provided in the Indenture  and subject to certain  limitations
herein and therein set forth, the transfer of this Note may be registered on the
register of the Notes,  upon surrender of this Note for registration of transfer
at the Bank,  or at such other  agencies  as may be  designated  pursuant to the
Indenture,  duly endorsed by, or accompanied by a written instrument of transfer
in form  satisfactory  to the Trustee or the Bank duly  executed  by, the holder
hereof or his attorney duly authorized in writing, and thereupon one or more new
Notes, of authorized  denominations and for the same aggregate principal amount,
will be issued to the designated transferee or transferees.

               The Notes are issuable only as registered  Notes without  coupons
in  denominations  of $1,000 or any amount in excess thereof that is an integral
multiple  of  $1,000.  As  provided  in the  Indenture,  and  subject to certain
limitations  herein and therein set forth, the Notes are exchangeable for a like
aggregate principal amount of Notes of other authorized denominations having the
same  interest  rate,  Stated  Maturity,   optional   redemption  or  repurchase
provisions,  if any, and Original Issue Date, as requested by the Securityholder
surrendering the same.

               No  service  charge  will be made  for any such  registration  of
transfer or exchange, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

               The Company,  the Trustee,  the Bank, the Security  registrar and
any agent of the Company,  the Trustee,  the Bank, or the Security registrar may
treat the  Securityholder  in whose name this Note is registered as the absolute
owner hereof for the

                                      -5-

<PAGE>

     purpose of receiving payment as herein provided and for all other purposes,
     whether or not this Note is overdue,  and neither the Company, the Trustee,
     the Bank,  the Security  registrar  nor any such agent shall be affected by
     notice to the contrary.

               If an Event of Default (as defined in the Indenture) with respect
to the Notes shall occur and be  continuing,  the principal of all the Notes may
be declared  due and  payable in the manner and with the effect  provided in the
Indenture.

               The  Indenture  permits,   with  certain  exceptions  as  therein
provided,  the  amendment  thereof  and  the  modification  of  the  rights  and
obligations  of the Company and the rights of the holders of the  Securities  of
any series  under the  Indenture  at any time by the Company with the consent of
the  holders  of not less  than 66 2/3% in  aggregate  principal  amount  of the
Securities at the time  Outstanding  to be affected  (voting as one class).  The
Indenture  also  permits the Company and the Trustee to enter into  supplemental
indentures  without the consent of the holders of  Securities  of any series for
certain purposes specified in the Indenture,  including the making of such other
provisions  in regard to matters  arising  under the  Indenture  which shall not
adversely affect the interest of the holders of such  Securities.  The Indenture
also contains  provisions  permitting  the holders of specified  percentages  in
aggregate  principal  amount  of the  Securities  of  any  series  at  the  time
Outstanding,  on behalf of the holders of all the Securities of such series,  to
waive  compliance  by the Company with certain  provisions  of the Indenture and
certain past  defaults  under the  Indenture  and their  consequences.  Any such
consent  or waiver by the holder of this Note shall be  conclusive  and  binding
upon such holder and upon all future holders of this Note and of any Note issued
upon the  registration  of  transfer  hereof or in  exchange  herefor or in lieu
hereof whether or not notation of such consent or waiver is made upon this Note.

               The  Indenture  provides  that no holder of any  Security  of any
series may enforce any remedy with  respect to such series  under the  Indenture
except in the case of refusal or neglect of the Trustee to act after notice of a
continuing Event of Default and after written request by the holders of not less
than 33% in aggregate  principal  amount of the  Outstanding  Securities of such
series and the offer to the Trustee of reasonable indemnity;  provided, however,
that such provision  shall not prevent the holder hereof from enforcing  payment
of the principal of or interest on this Note.

               No  reference  herein to the  Indenture  and no provision of this
Note or of the  Indenture  shall alter or impair the  obligation of the Company,
which is absolute  and  unconditional,  to pay the  principal of and interest on
this Note at the  times,  place and rate,  and in the coin or  currency,  herein
prescribed.

               No recourse  shall be had for the payment of the  principal of or
the  interest  on this Note,  or for any claim based  hereon,  or  otherwise  in
respect  hereof,  or based on or in respect of the  Indenture  or any  indenture
supplemental  thereto,  against  any  incorporator,   stockholder,   officer  or
director, as such,

past, present or future, of the Company or any predecessor or
successor corporation, whether by virtue of any constitution, statute or rule of
law, or by the  enforcement of any assessment or penalty or otherwise,  all such
liability being, by the acceptance  hereof and as part of the  consideration for
the issue hereof, expressly waived and released.

               This Note shall be governed by and construed in  accordance  with
the laws of the State of New York.

& Co. or its  registered  assigns,  the  principal  sum of DOLLARS on the Stated
Maturity shown above and to pay interest on said principal sum from the Original
Issue Date shown  above if  interest  has not been paid on this Note or from the
most  recent  Interest  Payment  Date for which  interest  has been paid or duly
provided  for until  Stated  Maturity  or, if  applicable,  upon  redemption  or
repurchase at the rate per annum determined in accordance with the provisions on
the reverse  hereof,  depending on the Interest Rate Basis and the Spread and/or

an Interest  Payment  Date or on an Interest  Payment  Date,  the first day that
interest  shall be payable will be on the Interest  Payment Date  following  the
next  succeeding  Record  Date.  In the event of a  default  in the  payment  of
interest,  interest will be payable as provided in that certain Indenture, dated
as of March 24, 1999 (the "Indenture"),  by and between the Company and The Bank

               The  interest  so  payable  on the dates  specified  above  will,
subject to certain exceptions  provided in the Indenture,  be paid to the person
in whose name this Note is  registered  at the close of  business  on the Record
Date for such Interest  Payment  Date,  which shall be the date 15 calendar days
prior to each Interest  Payment Date whether or not such day shall be a Business
Day;  provided,  however,  that  interest  payable  at  Stated  Maturity  or, if
applicable,  upon  redemption or  repurchase,  shall be payable to the person to
whom  principal  shall be payable.  Payment of the  principal of and interest on
this  Note will be made at the Bank in U.S.  dollars;  provided,  however,  that
payments of interest (other than any interest payable at Stated Maturity or upon
redemption or repurchase) may be made at the option of the Company (i) by checks
mailed to the addresses of the persons  entitled thereto as such addresses shall
appear in the register of the Notes or (ii) by wire  transfer to persons who are
holders of record at such other  addresses that have been filed with the Bank on
or prior to the Record Date.

                              (FLOATING RATE NOTE)

               This Note is one of a duly  authorized  issue of debt  securities
(the  "Securities")  of the Company,  of a series  designated as its Medium-Term
Notes,  Series B (herein  called the  "Notes"),  limited  (except  as  otherwise
provided in the Indenture) in aggregate principal amount to $500,000,000, issued
and to be issued  under  the  Indenture,  to which  Indenture  and all  relevant
indentures  supplemental thereto reference is hereby made for a statement of the
respective rights, obligations, duties and immunities thereunder of the Company,
the Trustee,  the Bank and the Securityholder and the terms upon which the Notes
are, and are to be,  authenticated and delivered.  The Securities,  of which the
Notes constitute a series, may be issued in one or more series,  which different
series  may be issued in  various  aggregate  principal  amounts,  may mature at
different  times,  may bear  interest  at  different  rates,  may be  subject to
different  covenants  and Events of  Default  and may  otherwise  vary as in the
Indenture  provided.  All capitalized  terms not otherwise  defined herein shall
have the definitions assigned to them in the Indenture.

         Commencing with the applicable  Interest Reset Date first following the
Original Issue Date specified on the face hereof,  the rate at which interest on
this  Note  is  payable  shall  be  reset  daily,  weekly,  monthly,  quarterly,
semi-annually  or annually as shown on the face hereof.  The  interest  rate per
annum for each  interest  reset period  shall be  calculated  on the  applicable
Interest  Determination  Date  specified  on the face  hereof  and  shall be the
Interest Rate Basis specified on the face hereof,  determined in accordance with
the  provisions  of  the  applicable  heading  below,   adjusted  by  adding  or
subtracting a Spread and/or multiplying by a Spread Multiplier,  as the case may
be, specified on the face hereof; provided,  however, that (i) the interest rate
in effect from the  Original  Issue Date to the first  Interest  Reset Date with
respect to this Note will be the Initial  Interest  Rate  specified  on the face
hereof and (ii) the interest rate in effect for the ten days  immediately  prior
to the Stated Maturity or redemption or repurchase will be that in effect on the
tenth day preceding such Stated Maturity or redemption or repurchase.  Each such
adjusted rate shall be applicable on and after the Interest  Reset Date to which
it relates,  to, but not including,  the next succeeding  Interest Reset Date or
until the Stated Maturity, or the date of redemption or repurchase,  as the case
may be.  If any  Interest  Reset  Date  would  otherwise  be a day that is not a
Business Day, such Interest Reset Date shall be postponed to the next succeeding
day that is a Business Day (as defined below),  except that if the Interest Rate
Basis specified on the face hereof is LIBOR,  and if such Business Day is in the
next  succeeding   calendar  month,  such  Interest  Reset  Date  shall  be  the
immediately  preceding Business Day. Subject to provisions of applicable law and
except as specified  herein, on each Interest

                                      -5-

<PAGE>

     Reset Date the rate of interest  on this Note shall be the rate  determined
     in accordance with the provisions of the applicable heading below.

         All  percentages  resulting  from any  calculation on this Note will be
rounded,  if necessary,  to the nearest one  hundred-thousandth  of a percentage
point,  with five  one-millionths  of a percentage  point rounded  upward (e.g.,
9.876545% (or .09876545)  would be rounded to 9.87655% (or  .0987655)),  and all
dollar amounts used in or resulting from such calculation will be rounded to the
nearest cent with one-half cent being rounded upward.

DETERMINATION OF CD RATE.

         If the  Interest  Rate  Basis on this Note is the CD Rate,  the CD Rate
with  respect to this Note shall equal the rate on each  Interest  Determination
Date designated on the face hereof for negotiable certificates of deposit having
the Index Maturity designated on the face hereof as published in H.15(519) under
the  heading  "CDs  (Secondary  Market)."  In the  event  that  such rate is not
published  prior to 9:00  A.M.,  New York City  time,  on the  Calculation  Date
designated on the face hereof  pertaining to such Interest  Determination  Date,
then  the CD Rate  will be the  rate on such  Interest  Determination  Date  for
negotiable  certificates  of deposit  having the Index  Maturity as published in
Composite  Quotations under the heading  "Certificates of Deposit." If such rate
was neither  published in H.15(519)  by 9:00 A.M.,  New York City time,  on such
Calculation  Date nor in Composite  Quotations by 3:00 P.M., New York City time,
on such  date,  the CD Rate for that CD  Interest  Determination  Date  shall be
calculated  by the  Calculation  Agent and shall be the  arithmetic  mean of the
secondary  market offered  rates,  as of 10:00 A.M., New York City time, on that
Interest Determination Date, of three leading nonbank dealers of negotiable U.S.
dollar  certificates  of  deposit  in The  City  of  New  York  selected  by the
Calculation Agent for negotiable  certificates of deposit of major United States
money market banks with a remaining  maturity closest to the Index Maturity in a
denomination of $5,000,000;  provided, however, that if fewer than three dealers
selected as aforesaid by the Calculation  Agent are quoting as mentioned in this
sentence,  the rate of interest in effect for the applicable  period will be the
same as the CD Rate as adjusted for the Spread and/or Spread Multiplier,  as the
case may be, for the immediately preceding interest reset period.

         The CD Rate determined with respect to any Interest  Determination Date
will become effective on and as of the applicable  Interest Reset Date specified
on the face hereof; provided,  however, that (i) the interest rate in effect for
the period from the Original Issue Date to first Interest Reset Date will be the
Initial  Interest Rate specified on the face hereof,  and (ii) the interest rate
in  effect  for the ten  days  immediately  preceding  the  Stated  Maturity  or
redemption  will be that in  effect  on the  tenth  day  preceding  such  Stated
Maturity or redemption.

DETERMINATION OF COMMERCIAL PAPER RATE.

         If the Interest Rate Basis on this Note is the  Commercial  Paper Rate,
the Commercial Paper Rate with respect to this Note shall equal the Money Market
Yield (calculated as described

                                      -6-

     below) of the rate on each Interest  Determination  Date  designated on the
     face hereof for commercial  paper having the Index  Maturity  designated on
     the face hereof as  published in  H.15(519)  under the heading  "Commercial
     Paper."  In the event that such rate is not  published  prior to 9:00 A.M.,
     New York City time, on the  Calculation  Date designated on the face hereof
     pertaining to such Interest  Determination  Date, then the Commercial Paper
     Rate  will  be  the  Money  Market  Yield  of the  rate  on  such  Interest
     Determination  Date for  commercial  paper  having  the Index  Maturity  as
     published in Composite  Quotations under the heading "Commercial Paper." If
     such rate was neither  published in  H.15(519) by 9:00 A.M.,  New York City
     time, on such  Calculation  Date nor in Composite  Quotations by 3:00 P.M.,
     New York City  time,  on such  date,  the  Commercial  Paper  Rate for that
     Interest Determination Date will be calculated by the Calculation Agent and
     will be the Money Market Yield of the arithmetic mean of the offered rates,
     as of 11:00 A.M., New York City time, on that Interest  Determination Date,
     of  three  leading  dealers  of  commercial  paper  in The City of New York
     selected by the  Calculation  Agent for  commercial  paper having the Index
     Maturity  designated  on the face hereof  placed for an  industrial  issuer
     whose bond rating is "AA," or the equivalent,  from a nationally recognized
     rating agency; provided, however, that if fewer than three dealers selected
     as  aforesaid  by the  Calculation  Agent are quoting as  mentioned in this
     sentence,  the rate of interest in effect for the applicable period will be
     the same as the  Commercial  Paper Rate as adjusted  for the Spread  and/or
     Spread  Multiplier,  as the  case  may be,  for the  immediately  preceding
     interest reset period.

         "Money  Market  Yield"  shall  be a yield  (expressed  as a  percentage
rounded upwards,  if necessary,  to the next higher one-hundred  thousandth of a
percentage point) calculated in accordance with the following formula:

              Money Market Yield =              D x 360
                                             --------------          x 100
                                             360 - (D x M)

where "D" refers to the per annum  rate for  commercial  paper  quoted on a bank
discount  basis and expressed as a decimal;  and "M" refers to the actual number
of days in the period for which interest is being calculated.

         The  Commercial  Paper Rate  determined  with  respect to any  Interest
Determination  Date will become  effective on and as of the applicable  Interest
Reset  Date  specified  on the  face  hereof;  provided,  however,  that (i) the
interest rate in effect for the period from the Original Issue Date to the first
Interest  Reset Date will be the Initial  Interest  Rate  specified  on the face
hereof;  and (ii)  the  interest  rate in  effect  for the ten days  immediately
preceding the Stated  Maturity or redemption will be that in effect on the tenth
day preceding such Stated Maturity or redemption.

DETERMINATION OF LIBOR.

         If the Interest Rate Basis on this Note is LIBOR, LIBOR with respect to
this Note will be determined  by the  Calculation  Agent in accordance  with the
following provisions:

                                      -7-

<PAGE>

         (a) With  respect to any  Interest  Determination  Date,  LIBOR will be
determined by either (i) the  arithmetic  mean of the offered rates for deposits
in U.S.  dollars  having  the  Index  Maturity  designated  on the face  hereof,
commencing  on the second  Business  Day  immediately  following  such  Interest
Determination  Date,  which  appear on the Reuters  Screen LIBO Page as of 11:00
A.M.,  London time,  on that Interest  Determination  Date, if at least two such
offered  rates  appear on the  Reuters  Screen  LIBO Page,  or (ii) the rate for
deposits  in U.S.  dollars  having  the Index  Maturity  designated  on the face
hereof,  commencing  on the  second  Business  Day  immediately  following  such
Interest  Determination Date, that appears on the Telerate Page 3750 as of 11:00
a.m.,  London time, on such  Interest  Determination  Date.  If neither  Reuters
Screen LIBO Page nor Telerate  Page 3750 is specified on the face hereof,  LIBOR
will be determined as if Telerate Page 3750 had been specified.

         (b) With respect to an Interest  Determination Date on which fewer than
two offered  rates appear on the Reuters  Screen LIBO Page or no rate appears on
Telerate Page 3750 for the applicable  Index Maturity as described in (a) above,
LIBOR will be determined on the basis of the rates at approximately  11:00 A.M.,
London  time,  on such  Interest  Determination  Date at which  deposits in U.S.
dollars having the Index  Maturity  designated on the face hereof are offered to
prime  banks in the London  interbank  market by four major  banks in the London
interbank  market  selected by the  Calculation  Agent  commencing on the second
Business Day  immediately  following such Interest  Determination  Date and in a
principal  amount  not less  than  $1,000,000  that in the  Calculation  Agent's
judgment is representative  for a single transaction in such market at such time
(a  "Representative  Amount").  The Calculation Agent will request the principal
London  office of each of such banks to provide a quotation  of its rate.  If at
least two such  quotations are provided,  LIBOR for such Interest  Determination
Date  will  be the  arithmetic  mean of  such  quotations.  If  fewer  than  two
quotations are provided,  LIBOR for such Interest Determination Date will be the
arithmetic mean of the rates quoted at  approximately  11:00 A.M., New York City
time,  on such Interest  Determination  Date by three major banks in The City of
New York,  selected  by the  Calculation  Agent,  for loans in U.S.  dollars  to
leading  European banks having the specified  Index  Maturity  commencing on the
second Business Day immediately  following such Interest  Determination Date and
in a Representative  Amount;  provided,  however, that if fewer than three banks
selected as aforesaid by the Calculation  Agent are quoting as mentioned in this
sentence,  the rate of interest in effect for the applicable  period will be the
same as LIBOR as adjusted for the Spread and/or Spread  Multiplier,  as the case
may be, for the immediately preceding interest reset period.

         LIBOR determined with respect to any Interest  Determination  Date will
become  effective on and as of the  applicable  Interest Reset Date specified on
the face hereof; provided, however, that (i) the interest rate in effect for the
period from the Original Issue Date to the first Interest Reset Date will be the
Initial Interest Rate specified on the face hereof and (ii) the interest rate in
effect for the ten days immediately  preceding the Stated Maturity or redemption
will be that in effect  on the  tenth day  preceding  such  Stated  Maturity  or
redemption.

DETERMINATION OF FEDERAL FUNDS EFFECTIVE RATE.

                                      -8-

<PAGE>

         If the Interest Rate Basis on this Note is the Federal Funds  Effective
Rate,  the Federal  Funds  Effective  Rate with respect to this Note shall equal
with respect to each Interest  Determination  Date designated on the face hereof
the rate on such date for Federal  Funds as  published  in  H.15(519)  under the
heading "Federal Funds (Effective)" or, if not so published prior to 11:00 A.M.,
New York City  time,  on the  Calculation  Date  designated  on the face  hereof
pertaining to such Interest Determination Date, then the Federal Funds Effective
Rate  will be the  rate on such  Interest  Determination  Date as  published  in
Composite Quotations under the heading "Federal  Funds/Effective  Rate." If such
rate was neither  published in H.15(519) by 11:00 A.M.,  New York City time,  on
such  Calculation  Date nor in Composite  Quotations by 3:00 P.M., New York City
time,  on such  date,  the  Federal  Funds  Effective  Rate  for  such  Interest
Determination  Date will be calculated by the Calculation  Agent and will be the
arithmetic  mean of the rates,  as of 11:00  A.M.,  New York City time,  on that
Interest Determination Date, for the last transaction in overnight Federal Funds
arranged by three leading  brokers of Federal Funds  transactions in The City of
New York selected by the Calculation  Agent;  provided,  however,  that if fewer
than three brokers selected as aforesaid by the Calculation Agent are quoting as
mentioned in this  sentence,  the rate of interest in effect for the  applicable
period will be the same as the Federal Funds  Effective Rate as adjusted for the
Spread  and/or  Spread  Multiplier,  as the  case  may be,  for the  immediately
preceding interest reset period.

         The  Federal  Funds  Effective  Rate  determined  with  respect  to any
Interest  Determination  Date will become  effective on and as of the applicable
Interest Reset Date specified on the face hereof;  provided,  however,  that (i)
the interest  rate in effect for the period from the Original  Issue Date to the
first  Interest  Reset Date will be the Initial  Interest Rate  specified on the
face hereof;  and (ii) the interest rate in effect for the ten days  immediately
preceding the Stated  Maturity or redemption will be that in effect on the tenth
day preceding such Stated Maturity or redemption.

DETERMINATION OF PRIME RATE.

         If the  Interest  Rate Basis on this Note is the Prime Rate,  the Prime
Rate  with  respect  to the Note  shall  equal  with  respect  to each  Interest
Determination Date designated on the face hereof the rate set forth on such date
in H.15(519) under the heading "Bank Prime Loan." In the event that such rate is
not published  prior to 9:00 A.M., New York City time, on the  Calculation  Date
designated on the face hereof  pertaining to such Interest  Determination  Date,
then the Prime Rate will be the arithmetic mean (rounded upwards,  if necessary,
to the next higher one-hundred thousandth of a percentage point) of the rates of
interest  publicly  announced  by each bank that  appear on the  Reuters  Screen
USPRIMEONE  Page as such bank's prime rate or base lending rate as in effect for
that  Interest  Determination  Date. If fewer than four such rates but more than
one such rate  appear on the Reuters  Screen  USPRIMEONE  Page for the  Interest
Determination  Date,  the Prime  Rate will be the  arithmetic  mean of the prime
rates (quoted on the basis of the actual number of days in the year divided by a
360-day year) as of the close of business on such Interest Determination Date by
four  major  money  center  banks  in The  City  of  New  York  selected  by the
Calculation

                                      -9-
<PAGE>

Agent.  If fewer than two quotations  are provided,  the Prime Rate
shall be determined on the basis of the rates  furnished in The City of New York
by the appropriate  number of substitute banks or trust companies  organized and
doing business under the laws of the United States, or any State thereof, having
total equity  capital of at least $500 million and being subject to  supervision
or  examination  by a Federal or State  authority,  selected by the  Calculation
Agent to  provide  such  rate or  rates;  provided,  however,  that if the banks
selected as aforesaid by the  Calculation  Agent are not quoting as mentioned in
this sentence,  the rate of interest in effect for the applicable period will be
the same as the Prime Rate as adjusted for the Spread and/or Spread  Multiplier,
as the case may be, for the immediately preceding interest reset period.

         The Prime Rate  determined  with respect to any Interest  Determination
Date will  become  effective  on and as of the  applicable  Interest  Reset Date
specified on the face hereof;  provided,  however, that (i) the interest rate in
effect for the period from the Original  Issue Date to the first  Interest Reset
Date will be the Initial  Interest Rate  specified on the face hereof;  and (ii)
the interest  rate in effect for the ten days  immediately  preceding the Stated
Maturity or redemption  will be that in effect on the tenth day  preceding  such
Stated Maturity or redemption.

DETERMINATION OF TREASURY RATE.

         If the  Interest  Rate  Basis on this Note is the  Treasury  Rate,  the
Treasury  Rate with  respect  to this Note  shall  equal  with  respect  to each
Interest  Determination Date designated on the face hereof the rate for the most
recent  auction of direct  obligations of the United States  ("Treasury  bills")
having  the  Index  Maturity  designated  on the face  hereof  as  published  in
H.15(519) under the heading, "U.S. Government Securities/Treasury  Bills/Auction
Average  (Investment)" or, if not so published by 9:00 A.M., New York City time,
on the  Calculation  Date  designated  on the  face  hereof  pertaining  to such
Interest  Determination  Date,  the auction  average rate  (expressed  as a bond
equivalent,  on the  basis  of a year of 365 or 366  days,  as  applicable,  and
applied on a daily basis) for such auction as otherwise  announced by the United
States Department of the Treasury.  In the event that the results of the auction
of Treasury  bills having the Index  Maturity  designated on the face hereof are
neither  published  in  H.15(519)  by 9:00  A.M.,  New York City  time,  on such
Calculation Date, nor otherwise  published or reported as provided above by 3:00
P.M.,  New York  City  time on such  date,  or if no such  auction  is held in a
particular  week,  then the Treasury Rate shall be calculated by the Calculation
Agent and shall be a yield to maturity  (expressed as a bond equivalent,  on the
basis of a year of 365 or 366 days, as applicable, and applied on a daily basis)
of the  arithmetic  mean of the secondary  market bid rates as of  approximately
3:30 P.M.,  New York City time,  on such Interest  Determination  Date, of three
leading primary United States government  securities  dealers in The City of New
York selected by the Calculation  Agent,  for the issue of Treasury bills with a
remaining maturity closest to the specified Index Maturity;  provided,  however,
that if fewer than three dealers selected as aforesaid by the Calculation  Agent
are quoting as  mentioned in this  sentence,  the rate of interest in effect for
the applicable  period will be the same as the Treasury Rate as adjusted for the
Spread  and/or  Spread  Multiplier,  as the  case  may be,  for the  immediately
preceding interest reset period.

                                      -10-
<PAGE>

         The Treasury Rate determined with respect to any Interest Determination
Date will  become  effective  on and as of the  applicable  Interest  Reset Date
specified on the face hereof;  provided,  however, that (i) the interest rate in
effect for the period from the Original  Issue Date to the first  Interest Reset
Date will be the Initial  Interest Rate  specified on the face hereof;  and (ii)
the interest  rate in effect for the ten days  immediately  preceding the Stated
Maturity or redemption  will be that in effect on the tenth day  preceding  such
Stated Maturity or redemption.

Determination of CMT Rate

         If the Interest  Rate Basis on this Note is the CMT Rate,  the CMT Rate
with  respect  to  this  Note  shall  equal  with   respect  to  each   Interest
Determination  Date  designated  on the face  hereof the rate  displayed  on the
Designated   CMT  Telerate   Page  under  the  caption   "...Treasury   Constant
Maturities..  Federal Reserve Board Release H.15...  Mondays  Approximately 3:45
P.M.," under the column for the Index Maturity designated on the face hereof (i)
if the  Designated  CMT  Telerate  Page is 7055,  the  rate  for the  applicable
Interest  Determination  Date and (ii) if the  Designated  CMT Telerate  Page is
7052, the week, or the month,  as applicable,  ended  immediately  preceding the
week in which the Interest Determination Date occurs. If no page is specified on
the face hereof,  the  Designated  CMT Telerate Page shall be 7052, for the most
recent week. If such rate is no longer displayed on the relevant page, or if not
displayed by 3:00 P.M.,  New York City time,  on the related  Calculation  Date,
then the CMT Rate for such  Interest  Determination  Date will be such  Treasury
Constant  Maturity rate for the Index Maturity  designated on the face hereof as
published in the relevant H.15 (519). If such rate is no longer published, or if
not published by 3:00 P.M., New York City time, on the related Calculation Date,
then the CMT Rate for such  Interest  Determination  Date will be such  Treasury
Constant  Maturity  rate for the Index  Maturity  on the face  hereof  (or other
United  States   Treasury  rate  for  such  Index  Maturity  for  that  Interest
Determination  Date with  respect to such  Interest  Reset  Date) as may then be
published by either the Federal Reserve Board or the United States Department of
the Treasury that the Calculation  Agent determines to be comparable to the rate
formerly  displayed on the  Designated  CMT Telerate  Page and  published in the
relevant  H.15(519).  If such information is not provided by 3:00 P.M., New York
City time, on the related  Calculation Date, then the CMT Rate for that Interest
Determination  Date will be  calculated by the  Calculation  Agent and will be a
yield to maturity,  based on the arithmetic mean of the secondary market closing
offer side  prices as of  approximately  3:30 P.M.  (New York City time) on that
Interest  Determination  Date reported,  according to their written records,  by
three leading  primary  United States  government  securities  dealers  (each, a
"Reference  Dealer") in The City of New York selected by the  Calculation  Agent
(from  five  such  Reference  Dealers  selected  by the  Calculation  Agent  and
eliminating  the highest  quotation  (or, in the event of  equality,  one of the
highest)  and the lowest  quotation  (or, in the event of  equality,  one of the
lowest)), for the most recently issued direct noncallable fixed rate obligations
of  the  United  States   ("Treasury   Note")  with  an  original   maturity  of
approximately  the Index Maturity  designated on the face hereof and a remaining
term to maturity  of not less than such Index  Maturity  minus one year.  If two
Treasury Notes with an original maturity as described in

                                      -11-

<PAGE>

the preceding  sentence
have remaining terms to maturity equally close to the Index Maturity  designated
on the face hereof,  the quotes for the Treasury Note with the shorter remaining
term to maturity will be used. If the Calculation Agent cannot obtain three such
Treasury Note quotations, the CMT Rate for that Interest Determination Date will
be calculated by the Calculation  Agent and will be a yield to maturity based on
the  arithmetic   mean  of  the  secondary   market  offer  side  prices  as  of
approximately 3:30 P.M. (New York City time) on that Interest Determination Date
of three  Reference  Dealers in The City of New York  (from five such  Reference
Dealers selected by the Calculation  Agent and eliminating the highest quotation
(or, in the event of equality, one of the highest) and the lowest quotation (or,
in the event of  equality,  one of the  lowest)),  for  Treasury  Notes  with an
original  maturity of the number of years that is the next  highest to the Index
Maturity  designated on the face hereof and a remaining term to maturity closest
to such Index  Maturity and in an amount of at least $100  million.  If three or
four (and not five) of such  Reference  Dealers are quoting as described  above,
then the CMT  Rate  will be based on the  arithmetic  mean of the  offer  prices
obtained  and  neither  the  highest  nor  the  lowest  of such  quotes  will be
eliminated;  provided,  however,  that if fewer  than  three  Reference  Dealers
selected by the Calculation Agent are quoting as described  herein,  the rate of
interest in effect for the applicable period will be the same as the CMT Rate as
adjusted for the Spread  and/or Spread  Multiplier,  as the case may be, for the
immediately preceding Interest Reset Period.

         The CMT Rate determined with respect to any Interest Determination Date
will become effective on and as of the applicable  Interest Reset Date specified
on the face hereof; provided,  however, that (i) the interest rate in effect for
the period from the Original Issue Date to the first Interest Reset Date will be
the Initial  Interest Rate  specified on the face hereof;  and (ii) the interest
rate, in effect for the ten days  immediately  preceding the Stated  Maturity or
redemption  will be that in  effect  on the  tenth  day  preceding  such  Stated
Maturity or redemption.

         Notwithstanding  the  foregoing,  the interest rate hereon shall not be
greater  than the  Maximum  Interest  Rate,  if any,  or less  than the  Minimum
Interest Rate, if any,  shown on the face hereof.  The  Calculation  Agent shall
calculate  the interest  rate on this Note in  accordance  with the foregoing on
each Interest Determination Date.

         The  Interest  Rate on this Note  will in no event be  higher  than the
maximum rate permitted by Maryland law as the same may be modified by the United
States law of general applicability.

         The Calculation Agent will, upon the request of the Holder of this Note
provide  to such  Holder  the  interest  rate  hereon  then in  effect  and,  if
different,  the  interest  rate  which  will  become  effective  as of the  next
applicable Interest Reset Date.

         If any  Interest  Payment  Date  specified  on the  face  hereof  would
otherwise be a day that is not a Business  Day, the Interest  Payment Date shall
be postponed to the next day that is a Business Day, except that if (i) the rate
of interest on this Note shall be determined in accordance  with the  provisions
of the heading  "Determination of LIBOR" above, and (ii) such Business

                                      -12-
<PAGE>

Day is in
the next  succeeding  calendar  month,  such Interest  Payment Date shall be the
immediately  preceding  Business Day.  "Business Day" means any day other than a
Saturday or Sunday that (a) is not a day on which  banking  institutions  in the
state of Maryland,  or in New York, New York, are authorized or obligated by law
or executive order to be closed,  and (b) with respect to LIBOR Notes only, is a
day on which  dealings in deposits in U.S.  dollars are transacted in the London
interbank market.

        Interest  payments  for this Note will include  interest  accrued to but
excluding the Interest Payment Dates;  provided,  however,  that if the Interest
Reset Dates with respect to this Note are daily or weekly,  interest  payable on
any Interest  Payment  Date,  other than  interest  payable on any date on which
principal hereof is payable,  will include interest accrued to and including the
Record Date next preceding such Interest  Payment Date.  Accrued interest hereon
from the Original Issue Date or from the last date to which interest  hereon has
been paid, as the case may be, shall be an amount  calculated by multiplying the
face amount hereof by an accrued interest  factor.  Such accrued interest factor
shall be computed by adding the interest factor calculated for each day from the
Original  Issue  Date or from the last date to which  interest  shall  have been
paid,  as the case  may be,  to the date for  which  accrued  interest  is being
calculated.  The interest  factor  (expressed as a decimal rounded  upwards,  if
necessary,  to the next higher one hundred-thousandth of a percentage point) for
each such day shall be computed by dividing the interest  rate  (expressed  as a
decimal,   rounded   upwards,   if   necessary,   to   the   next   higher   one
hundred-thousandth of a percentage point) applicable to each such day by 360, in
the case of the Commercial Paper Rate, CD Rate,  LIBOR,  Federal Funds Effective
Rate or Prime Rate,  or by the actual  number of days in the year in the case of
the Treasury Rate or the CMT Rate.

               This  Note may not be  redeemed  by the  Company  prior to Stated
Maturity unless otherwise set forth on the face hereof.  Notwithstanding Section
4.03 of the Indenture,  pursuant to Section 4.01 thereof, and if so indicated on
the face of this Note,  this Note may be redeemed at the option of the  Company,
on any date on or after  the date set  forth on the face  hereof  in whole or in
part in increments of $1,000,  at a redemption price or prices designated on the
face hereof to be redeemed  together with interest  thereon  payable to the date
fixed for  redemption.  This Note may be so redeemed in whole or in part whether
or not other Notes of the same series are redeemed.

               Notice of redemption  or repurchase  will be given by the Company
by mail to holders of the Notes to be  redeemed,  not less than 30 nor more than
60  days  prior  to the  date  fixed  for  redemption,  all as  provided  in the
Indenture.  The Bank may carry out the  responsibilities  to be performed by the
Trustee required by Article Four of the Indenture.

        The Company is not required to  repurchase  Notes from holders  prior to
Stated Maturity unless  otherwise set forth on the face hereof.  If so indicated
on the face hereof, this Note may be repurchased by the Company at the option of
the holder on the dates and at the  prices  designated  thereon,  in whole or in
part in increments of $1,000,  together with interest  payable to the

date. For book-entry notes, unless otherwise specified on the face of this Note,
holders  must deliver  written  notice to the Bank at least 30, but no more than
60, days prior to the date of  repurchase,  but no later than 5:00 p.m. New York
City time on the last day for giving notice. The written notice must specify the
principal  amount to be  repurchased  and must be  signed  by a duly  authorized
officer of the Depositary  participant  (signature  guaranteed).  For definitive
notes,  unless  otherwise  specified  on the  face of this  Note,  holders  must
complete  the "Option to Elect  Repayment"  on the reverse of this Note and then
deliver  this Note to the Bank at least 30,  but no more than 45,  days prior to
the date of  repurchase,  but no later than 5:00 p.m.  New York City time on the
last day for giving notice. All notices are irrevocable.

               In the event of  redemption  or  repurchase  of this Note in part
only,  a new Note or Notes of this  series,  having  the same  Stated  Maturity,
optional redemption or repurchase provisions,  Interest Rate and other terms and
provisions of this Note, in authorized  denominations in an aggregate  principal
amount equal to the unredeemed  portion hereof will be issued in the name of the
holder hereof upon the surrender hereof.

[Remarketing provisions, if any, to be included here]

               The Notes will not be subject to conversion,  amortization or any
sinking fund.

               As provided in the Indenture  and subject to certain  limitations
herein and therein set forth, the transfer of this Note may be registered on the
register of the Notes,  upon surrender of this Note for registration of transfer
at the Bank,  or at such other  agencies  as may be  designated  pursuant to the
Indenture,  duly endorsed by, or accompanied by a written instrument of transfer
in form  satisfactory  to the Trustee or the Bank duly  executed  by, the holder
hereof or his attorney duly authorized in writing, and thereupon one or more new
Notes, of authorized  denominations and for the same aggregate principal amount,
will be issued to the designated transferee or transferees.

               The Notes are issuable only as registered  Notes without  coupons
in  denominations  of $1,000 or any amount in excess thereof that is an integral
multiple  of  $1,000.  As  provided  in the  Indenture,  and  subject to certain
limitations  herein and therein set forth, the Notes are exchangeable for a like
aggregate principal amount of Notes of other authorized denominations having the
same  Interest  Rate,  Stated  Maturity,   optional   redemption  or  repurchase
provisions,  if any, and Original Issue Date, as requested by the Securityholder
surrendering the same.

               No  service  charge  will be made  for any such  registration  of
transfer or exchange, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

               The Company,  the Trustee,  the Bank, the Security  registrar and
any agent of the Company,  the Trustee,  the Bank, or the Security registrar may
treat the  Securityholder  in whose name this Note is registered as the absolute
owner hereof for the purpose of receiving payment as herein provided and for all
other  purposes,  whether or not this Note is overdue,  and neither the Company,
the  Trustee,  the Bank,  the  Security  registrar  nor any such agent  shall be
affected by notice to the contrary.

               If an Event of Default (as defined in the Indenture) with respect
to the Notes shall occur and be  continuing,  the principal of all the Notes may
be declared  due and  payable in the manner and with the effect  provided in the
Indenture.

               The  Indenture  permits,   with  certain  exceptions  as  therein
provided,  the  amendment  thereof  and  the  modification  of  the  rights  and
obligations  of the Company and the rights of the holders of the  Securities  of
any series  under the  Indenture  at any time by the Company with the consent of
the  holders  of not less  than 66 2/3% in  aggregate  principal  amount  of the
Securities at the time  outstanding  to be affected  (voting as one class).  The
Indenture  also  permits the Company and the Trustee to enter into  supplemental
indentures  without the consent of the holders of  Securities  of any series for
certain purposes specified in the Indenture,  including the making of such other
provisions  in regard to matters  arising  under the  Indenture  which shall not
adversely affect the interest of the holders of such  Securities.  The Indenture
also contains  provisions  permitting  the holders of specified  percentages  in
aggregate  principal  amount  of the  Securities  of  any  series  at  the  time
outstanding,  on behalf of the holders of all the Securities of such series,  to
waive  compliance  by the Company with certain  provisions  of the Indenture and
certain past  defaults  under the  Indenture  and their  consequences.  Any such
consent  or waiver by the holder of this Note shall be  conclusive  and  binding
upon such holder and upon all future holders of this Note and of any Note issued
upon the  registration  of  transfer  hereof or in  exchange  herefor or in lieu
hereof whether or not notation of such consent or waiver is made upon this Note.

               The  Indenture  provides  that no holder of any  Security  of any
series may enforce any remedy with  respect to such series  under the  Indenture
except in the case of refusal or neglect of the Trustee to act after notice of a
continuing Event of Default and after written request by the holders of not less
than 33% in aggregate  principal  amount of the  outstanding  Securities of such
series and the offer to the Trustee of reasonable indemnity;  provided, however,
that such provision  shall not prevent the holder hereof from enforcing  payment
of the principal of or interest on this Note.

               No  reference  herein to the  Indenture  and no provision of this
Note or of the  Indenture  shall alter or impair the  obligation of the Company,
which is absolute  and  unconditional,  to pay the  principal of and interest on
this Note at the  times,  place and rate,  and in the coin or  currency,  herein
prescribed.

               No recourse  shall be had for the payment of the  principal of or
the  interest  on this Note,  or for any claim based  hereon,  or  otherwise  in
respect  hereof,  or based on or in respect of the  Indenture  or any  indenture
supplemental  thereto,  against  any  incorporator,   stockholder,   officer  or
director, as such, past, present or future, of the Company or any predecessor or

Constellation Energy Group, Inc.
c/o David A. Brune
250 W. Pratt Street, 20th Floor
Baltimore, Maryland 21201-2437

Gentlemen:

         This opinion is provided in connection with the registration  statement
(the  "Registration  Statement")  being  filed by  Constellation  Energy  Group,
("Constellation  Energy") with the  Securities and Exchange  Commission  ("SEC")
under the  Securities  Act of 1933,  regarding  the  proposed  issuance of up to
$500,000,000 principal amount of Medium Term Notes, Series B (the "Notes").

         I am an  attorney  in  the  Corporate  Unit  of  Constellation  Energy.
Constellation Energy is a Maryland corporation.  In connection with this opinion
I, together with other  attorneys  assisting  me, have  considered,  among other
things:  (1) the amended and restated articles of incorporation of Constellation
Energy as further  amended by  Articles  Supplementary  dated July 19,  1999 and
Certificate  of Correction  dated  September 13, 1999 (the  "Charter");  (2) the
by-laws of Constellation  Energy (the "By-Laws");  (3) the Indenture dated as of
March 24, 1999 from Constellation Energy to The Bank of New York under which the
Notes  will be  issued;  (4) the  corporate  proceedings  for the  approval  and
issuance of the Notes; (5) the Registration Statement;  (6) the agency agreement
(including  the  standard  purchase  provisions)  filed  as an  exhibit  to  the
Registration  Statement  (the "Purchase  Agreement");  (7) the provisions of the
Public Utility Holding Company Act of 1935 (the "1935 Act");  and (8) such other
documents,  transactions,  and matters of law as we deemed necessary in order to
render this opinion.

         This  opinion is subject to: (1) the  Registration  Statement  becoming
effective  under  the  Securities  Act  of  1933;  (2)  the  proper   execution,
authentication,  and delivery of the Notes upon  receipt of the  purchase  price
pursuant to the Purchase  Agreement;  and (3) the qualification of the Indenture
under the Trust Indenture Act of 1939.

         It is  my  opinion  that  when  there  has  been  compliance  with  the
Securities Act of 1933 and the applicable state securities laws, the Notes, when
issued and delivered pursuant to the Purchase Agreement, will constitute legally
issued and binding obligations of Constellation Energy.

         The  opinion  expressed  herein  concerns  only the  effect  of the law
(excluding  the principles of conflicts of law) of the State of Maryland and the
United States of America as currently in effect.

         This opinion is provided  solely for your benefit and may not be relied
upon by, or quoted to, any other person or entity, in whole or in part,  without
my prior written consent.

         I hereby  consent  to the  filing of this  opinion as an exhibit to the
Registration  Statement.  I am the  attorney  referred  to in  the  Registration
Statement and I consent to the  references to me in the  Registration  Statement
(and  any  amendments  thereto)  or the  prospectus  constituting  a part of the
Registration Statement (and any amendments or supplements thereto). In so doing,
I do not admit that I am in the  category of persons  whose  consent is required
under Section 7 of the  Securities  Act of 1933 or the rules and  regulations of
the SEC promulgated thereunder.

                                                              Very truly yours,
