PRICING SUPPLEMENT

The pricing supplement for each offering of notes will contain the specific
information and terms for that offering. The pricing supplement may 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  principally  relating to our
diversified energy-services 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. If you would like more information on these
provisions, review the indenture and its supplements that we filed with the SEC.
See Where You Can Find More Information on 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 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
is 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.

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.

                                       5

<PAGE>

                                     
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 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:

- -   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

- -   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.

                                       6

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:

 -   the note,  with the section  entitled  "Option to Elect  Repayment"  on the
     reverse of the note completed; or

- -    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

- -    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

We have provided a Glossary at the end of this prospectus to define the
capitalized words used in discussing the interest rates payable on the notes.

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,

                                       7

<PAGE>

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.

         Floating Rate Notes

         General

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

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

The applicable pricing supplement will also indicate the Spread and/or Spread
Multiplier, if any. In addition, any floating rate note may have a maximum or
minimum interest rate limitation.

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.

         Date of Interest Rate Change

The interest rate on each floating rate note may be reset daily, weekly,
monthly, quarterly, semi-annually, or annually. The Interest Reset Date will be:

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

         When Interest Is Paid

Interest is paid as follows:

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

                                       9

<PAGE>

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."

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."

(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

                                       10

<PAGE>

that Prime Rate Interest Determination Date.

(b) If fewer than four, but more than one, rates appear on the Reuters Screen
USPRIMEONE 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 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)."


                                       11

<PAGE>

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
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

                                       12

<PAGE>

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 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:


                                       13

<PAGE>

        (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 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

                                       14

<PAGE>

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:

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

- -  failure to pay for 30 days any interest on any note of any series;

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

- -  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, 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:

- -    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

- -    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.

By Agents

Notes may be sold on a continuing basis through agents designated by us. The
agents agree to use their reasonable efforts to solicit purchases for the period
of their 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 depends on the maturity of the note
they sell.

                          Per Note
                          --------

Public Offering Price     100%
Agents' Commissions       0.125% - 0.75%
Proceeds to BGE           --------------
 (before expenses)        99.875% - 99.25%

                          Total
                          ------
Public Offering Price     $500,000,000
Agents' Commissions       $625,000 - $3,750,000
                        ---------------------
Proceeds to BGE
  (before expenses)      $499,375,000 - $496,250,000


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.


                                       16

<PAGE>

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.

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.

connection with the notes offered pursuant to this prospectus. Cahill Gordon &
Reindel (a partnership including a professional corporation), New York, NY will
issue an opinion for any underwriters, dealers or agents. Cahill Gordon &

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 action or 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

                                      II-1

<PAGE>

improperly   received.   Notwithstanding  the  above  provisions,   a  court  of
appropriate jurisdiction, upon application of the Director or officer, may order
indemnification if it determines that in view of all the relevant circumstances,
the Director or officer is fairly and  reasonably  entitled to  indemnification;
however,  indemnification  with respect to any  Proceeding by or in the right of
the  corporation  or in which  liability was adjudged on the basis that personal
benefit was improperly received shall be limited to expenses.  A corporation may
advance reasonable expenses to a Director under certain circumstances, including
a written undertaking by or on behalf of such Director to repay the amount if it
shall  ultimately  be  determined  that the  standard of conduct  necessary  for
indemnification by the corporation has not been met.

     A  corporation  may  indemnify  and  advance  expenses to an officer of the
corporation  to the  same  extent  that it may  indemnify  Directors  under  the
statute.

     The  indemnification  and advancement of expenses provided or authorized by
this statute may not be deemed exclusive of any other rights, by indemnification
or otherwise,  to which a Director or officer may be entitled under the charter,
by-laws, a resolution of shareholders or directors, an agreement or otherwise.

     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

                                      II-2

<PAGE>

be permitted by law. No amendment of the Charter of the Corporation 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."

     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

                                      II-4

<PAGE>

         the Securities Exchange Act of 1934 that are incorporated by reference
         in the Registration Statement.

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

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

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

(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, Lehman Brothers
Inc., and Goldman, Sachs & Co. (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 A
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 _____,
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:

              (a) A registration statement on Form S-3 (No. 333-_____), which
also serves as a post-effective amendment to the registration statement on Form
S-3 (No. 333-24855), 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

<PAGE>

including (i) the prospectus included therein dated ___________, 1999 (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 light of the
circumstances under which they were made, not misleading.

      3. Appointment as Agent; Solicitations as Agent.


                                      - 2 -

<PAGE>

              (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 City of Baltimore
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.

              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.


                                     - 3 -

<PAGE>

              (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 _________(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, 39 W. Lexington Street,
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 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

                                     - 4 -

<PAGE>

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 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

                                     - 5 -

<PAGE>

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:

              (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.

                                     - 6 -

<PAGE>

            (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;

                     (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

                                     - 7 -

<PAGE>

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


                                     - 8 -

<PAGE>

                     (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, Vice
Chairman, 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 investigation and relying upon opinions of counsel to
the extent legal matters 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, except as set forth or contemplated in the
Prospectus or as described in such certificate.

              (f) At the Closing Date, the Agents shall have received a letter,
dated the Closing Date, of PricewaterhouseCoopers LLP, 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
              BGE'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 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

                                     - 10 -

<PAGE>

              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
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

                                     - 11 -

<PAGE>

contained in the Registration Statement and Prospectus (except as to the matters
referred to in their opinion rendered pursuant to subheading (ix) 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 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

                                     - 12 -

<PAGE>

requested by the Agents) with a certificate of the Chairman, Vice 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 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

                                     - 13 -

<PAGE>

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, 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 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 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,

                                     - 15 -
<PAGE>

                                    


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 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),

                                     - 16 -

<PAGE>

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 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

                                     - 17 -

<PAGE>

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
telecommunication. Notices to Lehman Brothers Inc. shall be delivered or

                                                                      Exhibit B

                            ADMINISTRATIVE PROCEDURES


      The Medium-Term Notes, Series A 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. and
Goldman, Sachs & Co. 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 ____________ (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 __________, 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 __________.

              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.


I.    GENERAL PROCEDURES


  Aggregate
  Principal Amount          $500,000,000


 Issue Date                 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

<PAGE>

                            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
                            mature on an Interest Payment Date (as defined
                            below).

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


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 to 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.

                            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

                            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

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

                            confirmations and settlements may resume, subject to
                            the provisions of "Delivery of Prospectus" below.

                            Outdated stickers, and copies of the Prospectus to

                            for files), will be destroyed.

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  
                            purchaser prior to or together  with the earlier of

                            purchaser.  The Company  shall ensure  that the 
                            Presenting Agent  receives  copies of the Prospectus
                            and each amendment or  supplemen  thereto (including
                            appropriate  pricing  stickers) in such quantities
                            and within  such  time  limits  as  will  enabl  the

                            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

                            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

                            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 hereof),  its original 
                            issuance date and (ii) with respect to any Globa
                            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, th 
                            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.

                            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

                            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  $200,000,000 in 
                            aggregate principal  amount,  one Global Security
                            will be  authenticated  and issued to represent
                            each  $200,000,000  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
                            $200,000,000.

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

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 to the Company. The CUSIP number assigned 
                            to such Global  Security  shall, in  accordance with
                            CUSIP  Service  Bureau procedures,  be canceled  and
                            not  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.

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 A ("Notes") registered under the
registration statement referred to in Section 2(a). The Notes will be issued
under an Indenture, dated as of __________, 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-_____),which  also
     serves as a  Post-effective  amendment to the  registration  statement (No.
     333-24855),  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
     

<PAGE>


     Purchaser  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 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 payment of the
purchase price by certified or official bank check or checks in same day or New
York or Baltimore Clearing House funds drawn to the order of the Company, at the
office of the Company, 39 W. Lexington Street, Baltimore, Maryland, at the time
set forth in this Agreement or at such other time not later than seven full
business days thereafter as you and the Company determine, such time being
herein referred to as the "Closing Date." The Purchased Notes so to be delivered
will be in definitive fully registered form registered in such denominations, of
$1,000 or multiples thereof, and in such 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, unless prevented from doing so by
circumstances beyond its control, 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,
records maintained by the Depositary's participants.

               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
        Commission as required by Rule 424.

               (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 delivered under the Act, all

                                     - 3 -

<PAGE>

        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

Company of its obligations hereunder and to the following additional conditions
precedent:

               (a) Subsequent to the signing of this Agreement, you shall have
        received a letter of PricewaterhouseCoopers LLP, dated the Closing Date,
        confirming that they are independent public 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 schedule audited by them which are
               included in Baltimore Gas and Electric Company's (BGE) 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
               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

               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

               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

               specified date not more than five days prior to the Closing Date,

               period of the previous year, in operating revenues, operating
               income, net income or in earnings applicable to common stock,]
               except in all cases for changes or decreases which 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

               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.

               (b) 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.

               (c) Subsequent to the date of this Agreement, (i) there shall not
        have occurred any change or any development involving a prospective
        change not contemplated by the Prospectus in or affecting particularly

<PAGE>

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

        Federal authorities and there shall not have occurred an outbreak 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

                                     - 7 -

<PAGE>

               Indenture, which fact counsel need not verify by an inspection of
               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 this Agreement) 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

                                     - 8 -

<PAGE>

               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 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, the Interest Calculation
               Agency Agreement and the Letter of Representations 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 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
Statement and the Prospectus and related matters were discussed;  and,  although

                                     - 9 -

<PAGE>

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 (ix) 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,Vice Chairman, 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 or as described in such
        certificate.

               (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:

                      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

                                      -11-

        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 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

                                     - 12-

<PAGE>

        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
        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

                                     - 13 -

<PAGE>

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 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 39 W. Lexington Street, Baltimore,
Maryland 21201, telecopier (410) 234-5367;

               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

                                     - 14 -

<PAGE>

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.

13 of the Agency Agreement, the first and last sentences of Section 9 thereof
and, to the extent applicable, the Procedures. You and we agree to perform, to

provided to be performed by each of us in the Procedures.

               Our obligation to purchase Notes hereunder is subject to the
accuracy on the above Settlement Date of your representations and warranties
contained in Section 2 of the Agency Agreement (it being understood that such
representations and warranties shall relate to the Registration Statement and
the Prospectus as amended at such Settlement Date) and to your performance and
observance of all covenants and agreements contained in Sections 4 and 6
thereof. Our obligation hereunder is also subject to the following conditions:


                                     

<PAGE>

               (a) the satisfaction, at such Settlement Date, of each of the
conditions set forth in subsections (a), (b) and (d) through (g) of Section 5 of
the Agency Agreement (it being understood that each document so required to be
delivered shall be dated such Settlement Date and that each such condition and
the statements contained in each such document that relate to the Registration
Statement or the Prospectus shall be deemed to relate to the Registration
Statement or the Prospectus, as the case may be, as amended or supplemented at
the time of settlement on such Settlement Date and except that the opinion
described in Section 5(d) of the Agency Agreement shall be modified so as to
state that the Notes being sold 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 clause (ii)
of Section 5(d) of the Agency Agreement, and will conform to the description
thereof contained in the Prospectus as amended or supplemented at such
Settlement Date); and

               (b) there shall not have occurred (i) any change, or any
development involving a prospective change not contemplated by the Prospectus,
in or affecting particularly the business or properties of the Company which, in
our judgment, materially impairs the investment quality of the Notes, (ii) any
downgrading in the rating of the Company's debt securities by any "nationally
recognized statistical rating organization" (as defined for purposes of Rule
436(g) under the Act); (iii) any suspension or limitation of trading, other than
a temporary suspension in trading to provide for an orderly market, in
securities generally on the New York Stock Exchange, 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;
(iv) any banking moratorium declared by Federal or New York authorities; or (v)
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 our judgment, the effect of any
such outbreak, escalation, declaration, calamity or emergency makes it
impractical or inadvisable to proceed with completion of the sale of and payment
for the Notes.

               In further consideration of our agreement hereunder, you agree
that between the date hereof and the above Settlement Date, you will not offer
or sell, or enter into any agreement to sell, any debt securities of the Company
in the United States, other than sales of Notes, borrowings under your revolving

consummated, you shall remain responsible for the expenses to be paid or
reimbursed by you pursuant to Section 4 of the Agency Agreement and the
respective obligations of you and the undersigned pursuant to Section 7 shall
remain in effect. If for any reason our purchase of the above Notes is not
consummated other than because of our default or a failure to satisfy a
condition set forth in clause (iii), (iv) or (v) of paragraph (b) above, you
shall reimburse us, severally, for all out-of-pocket expenses reasonably
incurred by us in connection with the offering of the above Notes and not
otherwise required to be reimbursed pursuant to Section 4 of the Agency
Agreement.

                  FORM OF INTEREST CALCULATION AGENCY AGREEMENT

                    THIS   AGREEMENT   dated  as  of  March____,   1999  between
               Constellation   Energy  Group,  Inc.   (hereinafter   called  the
               "Issuer"), having its principal office at 39 W. Lexington Street,
               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, New York, New York 10286.

                             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 A (the "Notes") under an indenture
dated as of March____,  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  floating  rate  determined  by
reference to an interest rate formula (the "Floating

<PAGE>

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.

     3. The Issuer shall notify the Calculation Agent of the
issuance of any Floating Rate Notes prior to the issuance thereof and, at the

                                       2

<PAGE>

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, 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 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

                                       3
<PAGE>

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 own 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 or with, any of the Holders of the Notes;

                    (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 necessarily incidental thereto;

                    (iv) the  Calculation  Agent  shall be  protected  and shall
               incur no liability for or in respect of any action taken

                                       5

                  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, 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

                                       6

<PAGE>

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 hereinafter 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
               covenants that it shall appoint a successor  Calculation Agent as

                                       7

<PAGE>

               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)  incurred by such
               retiring Calculation Agent pursuant to paragraph 5 hereof.

                    (c) If at any time the Calculation  Agent shall resign 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
               appointed by the Issuer by an  instrument  in writing  filed with
               the  successor  Calculation  Agent  and  the  Trustee.  Upon  the

                                        8

<PAGE>

               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.

               of the  Corporation,  if such  Securities  are to be  subject  to
               redemption;

               of the principal  amount of Securities of that series which shall

               such global  Security may exchange such  interests for Securities

               and  denomination,  and the  circumstances  under  which any such

               Section 3.04 hereof,  and (iii) the name of the  Depositary  with
               respect to any global Security,  provided that a Depositary must,

                                       8

<PAGE>

               at the time of its  designation  and at all times while it serves
               as  Depositary,   be  a  clearing  agency  registered  under  the
               Securities  Exchange  Act of  1934,  as  amended,  and any  other
               applicable statute or regulation; and

                  (11) any other terms of that series.

     SECTION 3.02. Denominations,  Dates, Interest Payment and Record Dates, and
Place of Payment.  In the absence of any  provision to the contrary with respect
to the Securities of any particular  series, the Securities shall be issuable as
registered  Securities  without coupons in the  denominations  of $1,000 and any
multiple of $1,000. Every Security shall be dated the date of its authentication
and shall bear interest, if any, from the date specified in the Board Resolution
authorizing the issuance thereof.

     The  person  in whose  name any  Security  is  registered  at the  close of
business on any record date (as  hereinafter  in this Section 3.02 defined) with
respect to any  interest  payment date shall be entitled to receive the interest
payable on such interest payment date  notwithstanding  the cancellation of such
Security upon any registration of transfer or exchange  subsequent to the record
date and prior to such interest payment date; provided,  however, that if and to
the extent the  Corporation  shall default in the payment of the interest due on
such interest payment date, such defaulted interest shall be paid to the persons
in whose names outstanding Securities are registered at the close of business on
a subsequent  record date established by notice given by mail by or on behalf of
the  Corporation  to the holders of Securities  not less than 15 days  preceding
such  subsequent  record  date,  such  record date to be not less than five days
preceding  the  date of  payment  of such  defaulted  interest.  As used in this
Section 3.02, the term "record date" for the interest payable on any Security on
any interest  payment  date  (except a date for payment of  defaulted  interest)
shall mean the date, if any, specified in such Security as the "record date" for
the  interest  payable on such  Security on any  interest  payment date for such
Security (except a date for payment of defaulted interest on such Security).

     In the  absence  of any  provision  to the  contrary  with  respect  to the
Securities of any particular  series,  payment of principal of (and premium,  if
any) and interest,  if any, on the Securities of all series shall be made at the
Principal  Office  of the  Trustee,  or at any  agency to be  maintained  by the
Corporation for such purpose;  provided,  however, that payments of installments
of  interest,  if any,  on such  Securities  may be  made at the  option  of the
Corporation by check mailed to the addresses of the persons  entitled thereto as
such addresses appear in the Security register provided for in Section 3.04.

                                       9

     SECTION 3.03.  Execution of Securities.  The Securities  shall be signed in
facsimile  in the name and on behalf of the  Corporation  by the Chairman of the
Board, Chief Executive Officer,  Vice Chairman,  President or any Vice President
of the Corporation,  under its corporate seal (which may be printed, engraved or
otherwise  reproduced  thereon,  by  facsimile  or  otherwise),  attested by its
Secretary or an Assistant Secretary.  Only such Securities as shall bear thereon
a certificate of  authentication  substantially in the form set forth in Section
2.02,  executed  by the  Trustee,  shall be  entitled  to the  benefits  of this
Indenture or be valid or obligatory  for any purpose.  Such  certificate  by the
Trustee  upon any  Security  executed  by the  Corporation  shall be  conclusive
evidence  that the Security so  authenticated  has been duly  authenticated  and
delivered  hereunder  and that the holder is  entitled  to the  benefits of this
Indenture.

     In case any  officer of the  Corporation  who shall have  signed any of the
Securities, shall cease to be such officer before the Securities so signed shall
have been  authenticated  and  delivered by the  Trustee,  or disposed of by the
Corporation,  such Securities nevertheless may be authenticated and delivered or
disposed of as though the person who signed such Securities had not ceased to be
such officer of the Corporation; and any Security may be signed on behalf of the
Corporation  by such  persons  as, at the actual date of the  execution  of such
Security shall be the proper officers of the  Corporation,  although at the date
of the execution of this Indenture any such person was not such an officer.

     SECTION  3.04.   Exchange  and  Registration  of  Transfer  of  Securities.
Securities  of any  series may be  exchanged  for an equal  aggregate  principal
amount of  Securities  of other  authorized  denominations  of the same  series.
Securities to be exchanged  shall be surrendered at the Principal  Office of the
Trustee or at any agency to be maintained by the  Corporation  for such purpose,
as provided in Section 5.02, and the Corporation shall execute and register, and
the Trustee shall  authenticate and deliver in exchange therefor the Security or
Securities  which the  Securityholder  making the exchange  shall be entitled to
receive.

     The  Corporation  shall  keep at the  Principal  Office  of the  Trustee  a
register in which,  subject to such reasonable  regulations as it may prescribe,
the Corporation shall provide for registration of Securities and registration of
transfers of Securities as in this Article Three  provided.  Such register shall
be in written form or in any other form capable of being  converted into written
form within a reasonable  time. At all reasonable  times with  reasonable  prior
notice  such  register  shall  be open for  inspection  by the  Trustee  and the
Corporation.  The Trustee is hereby appointed Security registrar for the purpose
of registering Securities and registering the

                                       10

<PAGE>

transfers  of  Securities  as herein  provided.    Upon  due   presentment  for
registration  of transfer of any Security of a particular  series at such office
or agency and  compliance in full with the  conditions of this Section 3.04, the
Corporation  shall  execute,  the Security  registrar  shall  register,  and the
Trustee  shall  authenticate  and  deliver  in the  name  of the  transferee  or
transferees  a new  Security  or  Securities  of the  same  series  for an equal
aggregate principal amount.

     All Securities  presented for  registration  of transfer or for exchange or
payment shall (if so required by the  Corporation or the Security  registrar) be
duly endorsed by, or be  accompanied  by a written  instrument or instruments of
transfer in form satisfactory to the Corporation and the Security registrar duly
executed by, the holder or his attorney duly authorized in writing.

     No  service  charge  shall  be made for any  exchange  or  registration  of
transfer  of  Securities,  but the  Corporation  may  require  payment  of a sum
sufficient to cover any tax or other governmental  charge that may be imposed in
connection therewith.
 
     Unless  otherwise  specified  with respect to the  Securities of a specific
series as contemplated by Section 3.01(10),  if at any time a Depositary for any
Securities of a series issued in global form notifies the Corporation that it is
unwilling or unable to continue as Depositary  for such  Securities or if at any
time a Depositary  for any Securities of such series issued in global form shall
no longer be eligible under the last clause of Section 3.01(10), the Corporation
shall  appoint a successor  Depositary  with respect to the  Securities  of such
series.  If a successor  Depositary for such  Securities is not appointed by the
Corporation  within 90 calendar days after the Corporation  receives such notice
or becomes aware of such  ineligibility,  or if an Event of Default with respect
to such  Securities  has  occurred and is  continuing,  such  Securities  shall,
notwithstanding the terms of the Securities of such series established  pursuant
to Section 3.01(10), no longer be issued in global form and the Corporation will
execute,  and the Trustee,  upon receipt of the Corporations  written order for
the  authentication and delivery of definitive  Securities of such series,  will
authenticate  and  deliver,  in  exchange  for  such  global  Security  from the
Depositary,   Securities  of  such  series  in  definitive  form  in  authorized
denominations, in an aggregate principal amount equal to the principal amount of
each global  Security  previously  delivered to such  Depositary and having like
terms and conditions.

     The Corporation  may at any time and in its sole discretion  determine that
the  Securities of any series issued in the form of a global  Security  shall no
longer be represented  by such global  Security.  In such event the  Corporation
will execute, and the Trustee,  upon receipt of the Corporation's  written order
for the authentication and delivery of definitive Securities of

                                       11

<PAGE>

such series, will  authenticated  and deliver,  in exchange for such global 
Security,  Securities of such series in  definitive  form in authorized 
denominations,  in an aggregate  principal  amount equal to the principal amount
of the Securities no longer to be represented by such global Security and having
like terms and conditions.

          If specified by the Corporation with respect to a series of Securities
pursuant to Section 3.01(10),  the Depositary for any Securities of such series 
represented by a global  Security may surrender such global Security in exchange
in whole or in part for definitive  Securities of such series having like terms
and  conditions  and in definitive  form on such terms as are acceptable to the
Corporation and such Depositary.  At such  Depositary's  request the Corporation
shall thereupon  execute, and the Trustee shall authenticate and deliver, (i) to
each person specified by such Depositary a new definitive Security or Securities
of the same series, having like terms and conditions and in any authorized 
denomination  as requested by such person in aggregate  principal  amount equal
to and in exchange for such  person's beneficial interest in the global Security
so surrendered  and (ii) to such  Depositary a new global  Security which is of
like terms and conditions and in a denomination  equal to the  difference,  if 
any,  between the principal amount of the surrendered  global Security and the
aggregate  principal amount of definitive  Securities  delivered to each such
person as provided in clause(i).

         Such  Securities in definitive  form issued  pursuant to the preceding 
paragraphs of this Section 3.04 shall be registered in such names and in such 
authorized  denominations as the Depositary,  pursuant to instructions from its
direct or indirect participants, or otherwise,  shall  instruct the Corporation.
After  authentication,  the Trustee shall deliver such  definitive Securities to
the persons in whose names such Securities are so registered.

     SECTION 3.05. Mutilated,  Destroyed, Lost or Stolen Securities. In case any
temporary or permanent Security shall become mutilated or be destroyed,  lost or
stolen,   the   Corporation  in  its  discretion  may  execute,   and  upon  the
Corporation's  written request the Trustee shall authenticate and deliver, a new
Security of the same series, bearing a number not contemporaneously outstanding,
in exchange and  substitution for the mutilated  Security,  or in lieu of and in
substitution  for the Security so destroyed,  lost or stolen.  In every case the
applicant for a substituted  Security shall furnish to the  Corporation,  to the
Security  registrar,  any  paying  agent and to the  Trustee  such  security  or
indemnity  as may be  required  by them to save each of them  harmless,  and, in
every case of  destruction,  loss or theft,  the applicant shall also furnish to
the  Corporation,  to the  Security  registrar,  to any paying  agent and to the

                                       12

<PAGE>

Trustee evidence to their satisfaction of the destruction, loss or theft of such
Security and of the ownership thereof.

The Trustee may authenticate any substituted  Security and deliver the same upon
the written request or authorization of any officer of the Corporation. Upon the
issuance of any substituted Security, the Corporation may require the payment of
a sum  sufficient  to cover  any tax or other  governmental  charge  that may be
imposed in relation  thereto and any other expenses,  including  counsel fees of
the Corporation,  the Trustee,  any paying agent or Security registrar connected
therewith.  In case any  Security  which has matured or is about to mature shall
become mutilated or be destroyed,  lost or stolen,  the Corporation may, instead
of issuing a  substitute  Security,  pay or  authorize  the  payment of the same
(without  surrender  thereof except in the case of a mutilated  Security) if the
applicant  for such payment shall  furnish to the  Corporation,  to the Security
registrar, any paying agent and to the Trustee such security or indemnity as may
be required by them to save each of them harmless  and, in case of  destruction,
loss or theft, evidence satisfactory to the Corporation,  the Security registrar
and the Trustee of the  destruction,  loss or theft of such  Security and of the
ownership thereof.

Every  substituted  Security  issued  pursuant to the provisions of this Section
3.05 by virtue of the fact that any Security is destroyed,  lost or stolen shall
constitute an additional contractual  obligation of the Corporation,  whether or
not the destroyed, lost or stolen Security shall be enforceable at any time, and
shall  be  entitled  to  all  the  benefits  of  this   Indenture   equally  and
proportionately  with any and all other  Securities duly issued  hereunder.  All
Securities shall be held and owned upon the express condition that the foregoing
provisions  are  exclusive  with  respect  to  the  replacement  or  payment  of
mutilated, destroyed, lost or stolen Securities and shall preclude to the extent
permitted by law any and all other rights or remedies notwithstanding any law or
statute  existing  or  hereafter  enacted to the  contrary  with  respect to the
replacement  or payment of negotiable  instruments or other  securities  without
their surrender.

     SECTION 3.06.  Temporary  Securities.  Pending the preparation of permanent
Securities  of any series,  the  Corporation  may execute and the Trustee  shall
authenticate and deliver temporary  Securities (printed or lithographed) of such
series.  Temporary  Securities of any series shall be issuable in any authorized
denomination,  and substantially in the form of the permanent Securities of such
series, but with such omissions, insertions and variations as may be appropriate
for  temporary  Securities  of  such  series,  all as may be  determined  by the
Corporation. Every such temporary Security shall be authenticated by the Trustee
upon the same conditions and in substantially the same manner, and with the same
effect, as the permanent  Securities of such series.  Without unreasonable delay
the Corporation will execute and deliver to the Trustee permanent Securities of

                                       13

<PAGE>

such series and thereupon any or all temporary  Securities of such series may be
surrendered  in exchange  therefor at the Principal  Office of the Trustee or at
any agency to be maintained by the  Corporation  for such purpose as provided in
Section  5.02,  and the Trustee shall  authenticate  and deliver in exchange for
such  temporary  Securities  an equal  aggregate  principal  amount of permanent
Securities of such series. Such exchange shall be made by the Corporation at its
own  expense and without any charge  therefor  except that the  Corporation  may
require  payment  of a sum  sufficient  to cover  any tax or other  governmental
charge  that  may be  imposed  in  relation  thereto.  Until so  exchanged,  the
temporary Securities of any series shall in all respects be entitled to the same
benefits under, and be subject to the terms and conditions of, this Indenture as
permanent Securities of the same series authenticated and delivered hereunder.

     SECTION  3.07.   Cancellation  of  Securities  Paid,  etc.  All  Securities
surrendered  for the purpose of payment,  exchange or  registration  of transfer
shall,  if  surrendered  to  the  Corporation  or any  agent  for  exchange  and
registration  of transfer,  be surrendered to the Trustee for  cancellation  and
promptly  cancelled by it, or, if surrendered to the Trustee,  shall be promptly
cancelled by it, and no  Securities  shall be issued in lieu  thereof  except as
expressly  permitted by any of the  provisions  of this  Indenture.  The Trustee
shall  dispose of such  cancelled  securities in its  customary  manner.  If the
Corporation shall acquire any of the Securities, however, such acquisition shall
not operate as a satisfaction of the indebtedness represented by such Securities
unless and until the same are surrendered to the Trustee for cancellation.

     SECTION 3.08 CUSIP Numbers.  The  Corporation in issuing the Securities may
use "CUSIP"  numbers (if then  generally in use),  and, if so, the Trustee shall
use  "CUSIP"  numbers in notices of  redemption  as a  convenience  to  Holders;
provided that any such notice may state that no representation is made as to the
correctness  of such numbers either as printed on the Securities or as contained
in any notice of a redemption  and that reliance may be placed only on the other
identification numbers printed on the Securities,  and any such redemption shall
not be affected by any defect in or omission of such  numbers.  The  Corporation
will promptly notify the Trustee of any change in the "CUSIP"numbers.

                                  ARTICLE FOUR
                            REDEMPTION OF SECURITIES

     SECTION  4.01.  Applicability  of This  Article.  Redemption  of Securities
(whether by operation of a sinking fund or  otherwise)  as permitted or required
by any form of  Security  issued  pursuant  to this  Indenture  shall be made in
accordance with such form of Security and this Article; provided,  however, that

                                       14

<PAGE>

if any provision of any such form of Security  shall conflict with any provision
of this Article, the provision of such form of Security shall govern.  Except as
otherwise set forth in the form of Security for such series, each Security shall
be  subject  to  partial  redemption  only in the  amount of $1,000 or  integral
multiples of $1,000.

     SECTION 4.02.  Election to Redeem:  Notice to Trustee.  The election of the
Corporation  to redeem any  Securities  shall be  evidenced  by or pursuant to a
Board  Resolution.  In case of any redemption at the election of the Corporation
of less than all of the Securities of any  particular  series,  the  Corporation
shall, at least 45 days prior to the date fixed for redemption (unless a shorter
notice shall be satisfactory to the Trustee) notify the Trustee of such date and
of the principal amount of Securities of that series to be redeemed.

     SECTION 4.03. Selection of Securities to be Redeemed.  If less than all the
Securities of a particular series are to be redeemed,  the Trustee shall select,
in such  manner as in its sole  discretion  it shall deem  appropriate  and fair
(which may be by lot), the  Securities or portions  thereof of such series to be
redeemed.  The Trustee shall promptly  notify the  Corporation in writing of the
Securities  selected for redemption and, in the case of any Securities  selected
for partial  redemption,  the principal  amount thereof to be redeemed.  For all
purposes  of  this  Indenture,   unless  the  context  otherwise  requires,  all
provisions relating to the redemption of Securities shall relate, in the case of
any  Security  redeemed  or to be redeemed  only in part,  to the portion of the
principal amount of such Security which has been or is to be redeemed.

     SECTION 4.04. Notice of Redemption.  Notice of redemption shall be given by
first-class mail, postage prepaid,  mailed not later than the thirtieth day, and
not earlier than the sixtieth day,  prior to the date fixed for  redemption,  to
each holder of  Securities  to be redeemed,  at his address as it appears on the
registry books of the Corporation.

     With respect to  Securities  of each series to be redeemed,  each notice of
redemption shall state:

     (1) the identity of the securities, including cusip numbers.

     (2) the date fixed for redemption for Securities of such series;

     (3) the  redemption  price at which  Securities  of such  series  are to be
redeemed;  

     (4) if less than all outstanding  Securities of such particular  series are
to be redeemed, the identification (and, in the case of partial redemption,  the

                                       15

<PAGE>

respective principal amounts) of the particular  Securities to be redeemed;

     (5) that on the date fixed for  redemption,  the redemption  price at which
such  Securities  are to be redeemed  will become due and payable upon each such
Security or portion thereof,  and that interest thereon,  if any, shall cease to
accrue on and after said date;

     (6) the place or places where such  Securities  are to be  surrendered  for
payment of the redemption price at which such Securities are to be redeemed; and


     (7) that the redemption is for a sinking fund, if such is the case.


     Notice of  redemption  of  Securities to be redeemed at the election of the
Corporation shall be given by the Corporation or, at the Corporation's  request,
by the Trustee in the name and at the expense of the Corporation.  The notice if
mailed in the manner herein provided shall be conclusively presumed to have been
duly given,  whether or not the holder  receives  such  notice.  In any case,  a
failure to give such notice by mail or any defect in the notice to the holder of
any Security  designated  for  redemption as a whole or in part shall not affect
the validity of the proceedings for the redemption of any other Security.

     SECTION 4.05.  Deposit of Redemption  Price.  Prior to or on the redemption
date  specified in the notice of  redemption  given as provided in Section 4.04,
the Corporation  will deposit with the Trustee or with one or more paying agents
an  amount  of  money  sufficient  to  redeem  on the  redemption  date  all the
Securities so called for redemption at the  applicable  redemption  price,  such
deposit  will be made before the  deadline  with which the Trustee or any paying
agent must settle with the Depository Trust Company, if applicable.

     SECTION 4.06. Payment of Securities Called for Redemption. If any notice of
redemption  has been  given as  provided  in Section  4.04,  the  Securities  or
portions of  Securities  with  respect to which such notice has been given shall
become  due and  payable  on the date and at the place or places  stated in such
notice at the applicable redemption price. On presentation and surrender of such
Securities at a place of payment in said notice  specified,  the said Securities
or the specified  portions thereof shall be paid and redeemed by the Corporation
at the applicable redemption price.

     Upon  presentation  of any Security  redeemed in part only, the Corporation
shall  execute  and the  Trustee  shall  authenticate  and deliver to the holder
thereof, at the expense of the Corporation,  a new Security or Securities of the
same series, of authorized denominations. in aggregate principal amount equal to

                                       16

<PAGE>

the unredeemed portion of the Security so presented.

     Section 4.07. Delegation of Duties by Trustee.  Except in regard to Section
4.03, any reference in this Article to the Trustee with respect to its duties in
regard to the redemption of any  Securities  shall be deemed to also include any
entity  designated by the Corporation with the written consent of the Trustee to
act as its agent for the  performance  of all or any of its  duties  under  this
Article.

                                  ARTICLE FIVE
                     PARTICULAR COVENANTS OF THE CORPORATION

     SECTION  5.01.  To Pay  Principal  (and Premium if any) and  Interest.  The
Corporation  will duly and punctually pay, or cause to be paid, the principal of
(and premium,  if any) and interest,  if any, on each and every  Security at the
times  and place  and in the  manner  provided  herein  and in such  Securities.
Interest  upon  Securities   shall  be  payable  without   presentment  of  such
Securities,  and only to or upon the  written  order of the  registered  holders
thereof  determined as provided in Section 3.02. The Corporation  shall have the
right to  require  a  Securityholder,  in  connection  with the  payment  of the
principal  of (and  premium,  if any) or  interest,  if any, on a  Security,  to
present at the office or agency of the Corporation at which such payment is made
a certificate,  in such form as the Corporation may from time to time prescribe,
to enable the Corporation to determine its duties and  liabilities  with respect
to any taxes,  assessments or  governmental  charges which it may be required to
deduct or  withhold  therefrom  under any  present  or future  law of the United
States of America or of any state, county, municipality or taxing or withholding
authority therein, and the Corporation shall be entitled to determine its duties
and  liabilities  with respect to such  deduction or withholding on the basis of
information contained in such certificate or, if no such certificate shall be so
presented, on the basis of any presumption created by any such law, and shall be
entitled to act in accordance with such determination.

     SECTION  5.02.  To  Maintain  Office or Agency.  So long as any  Securities
remain outstanding,  the Corporation will maintain an office or agency where the
Securities  may be presented for payment,  where the Securities may be presented
for  registration  of transfer  and exchange as in this  Indenture  provided and
where notices or demands to or upon the Corporation in respect of the Securities
or of this Indenture may be served.  The Corporation  hereby initially  appoints
the Trustee as its agent for all such purposes until otherwise designated by the
Corporation  in a written  notice to the  Trustee,  the office or agency for all
such  purposes  shall  be the  Principal  Office  of the  Trustee.  In case  the
Corporation  shall at any time  designate a different  office or agency for such
purposes,  but shall fail to maintain  such  office or agency,  or shall fail to

                                       17

give notice to the Trustee of any change in the location  thereof,  presentation
and demand may be made and notices may be served,  in respect of the  Securities
or of  this  Indenture,  at  the  Principal  Office  of  the  Trustee,  and  the
Corporation   hereby  appoints  the  Trustee  its  agent  to  receive  all  such
presentations, surrenders, notices and demands.

     In addition to any such office or agency the  Corporation  may from time to
time  constitute  and appoint one or more paying  agents for the payment of such
Securities,  in one or more other cities, and may from time to time rescind such
appointments, as the Corporation may deem desirable or expedient.

     SECTION 5.03. To Fill a Vacancy in the Office of Trustee.  The Corporation,
whenever  necessary  to avoid or fill a vacancy in the office of  Trustee,  will
appoint, in the manner provided in Article Eight, a Trustee, so that there shall
at all times be a Trustee hereunder.

     SECTION 5.04.  Appointment of Paying Agents; Money for Security Payments to
Be Set Aside in Trust;  Transfer or Moneys Held by Paying  Agents.  (a) If as to
any series of  Securities,  the  Corporation  shall appoint a paying agent other
than the Trustee,  it will cause such paying agent to execute and deliver to the
Trustee an  instrument  in which such paying agent shall agree with the Trustee,
subject to the provisions of this Section 5.04:

          (1) that it will hold all sums held by it as such paying agent for the
     payment of the principal of (and premium,  if any) or interest,  if any, on
     such  Securities in trust for the benefit of the holders of the  Securities
     entitled  thereto,  or for the benefit of the Trustee,  as the case may be,
     until such sums shall be paid out to such  holders or  otherwise  as herein
     provided;

          (2)  that it will  give  the  Trustee  notice  of any  failure  by the
     Corporation  in the making of any deposit  with such  paying  agent for the
     payment of principal of (and premium, if any) or interest,  if any, on such
     Securities  which  shall  have  become  payable  and of any  default by the
     Corporation in making any payment of the principal of (and premium, if any)
     or interest on such Securities when the same shall be due and payable, and

          (3)  that it will at any  time  during  the  continuance  of any  such
     default,  upon the written  request of the  Trustee,  forthwith  pay to the
     Trustee all sums so held in trust by such paying agent.

     (b) If the  Corporation  shall act as its own paying agent as to any series
of  Securities,  it will,  on or before each due date of the  principal  of (and
premium, if any) or interest, if any, on such Securities,  set aside and hold in
trust for the benefit of the holders of such Securities  entitled  thereto a sum

                                       18

<PAGE>

sufficient  (together  with any sums  deposited  with any other paying agent for
such purpose) to pay such principal (and premium,  if any) or interest,  if any,
so becoming due and will notify in writing the Trustee of any,  failure by it to
take such action.  Whenever the Corporation shall have one or more paying agents
with respect to any particular series of Securities,  it will, on or before each
due date of the  principal  of (and  premium,  if any) or interest if any on the
Securities,  deposit with a paying agent a sum  sufficient to pay such principal
(and premium, if any) or interest so becoming due, such sums to be held in trust
for the benefit of the holders of such Securities entitled thereto,  and (unless
the paying  agent is the  Trustee)  the  Corporation  will notify in writing the
Trustee of failure by it to take such action.

     (c)  Anything in this Section  5.04 to the  contrary  notwithstanding,  the
Corporation may at any time, for the purpose of obtaining the  satisfaction  and
discharge of this Indenture,  or for any other purpose,  pay or cause to be paid
to the Trustee all sums held in trust by the  Corporation or any paying agent as
required by this  Section  5.04,  such sums to be held by the  Trustee  upon the
trusts herein contained.

     (d)  Anything in this Section  5.04 to the  contrary  notwithstanding,  the
agreement  to hold sums in trust as provided in this  Section 5.04 is subject to
the provisions of Sections 13.03 and 13.04.

     SECTION 5.05. Maintenance of Corporate Existence, Rights and Franchises. So
long as any of the Securities  shall be outstanding,  the Corporation will do or
cause to be done all things  necessary  to  preserve  and keep in full force and
effect its corporate existence,  rights and franchises to carry on its business;
provided that nothing in this Section 5.05 shall  prevent (i) any  consolidation
or merger of the Corporation,  or any sale or conveyance of all or substantially
all  its  property  and  assets,  permitted  by  Article  Twelve,  or  (ii)  the
liquidation or dissolution of the Corporation  after a sale or conveyance of all
or substantially all its property and assets permitted by Article Twelve.

     SECTION 5.06.  Certificate as to No Default.  The Corporation hereby agrees
to deliver to the Trustee,  within 120 days after the end of each fiscal year of
the  Corporation,  commencing  with the fiscal year ending December 31, 1999, an
Officers'  Certificate,  which need not comply  with the  provisions  of Section
16.05,  to the  effect  that,  to the  knowledge  of the  signers  thereof,  the
Corporation  is in  compliance  with all  conditions  and  covenants  under this
Indenture  and is not in default  under any  provision of this  Indenture or, if
such signers have knowledge of any such default, stating the same and the nature
and status thereof.

     SECTION 5.07 Calculation of Original Issue Discount. If the Corporation has
any  Outstanding  Securities  issued  with  original  issue  discount  that  are
outstanding  during  any  calendar  year,  the  Corporation  shall file with the
Trustee  promptly  at  the  end of  each  calendar  year  (i) a  written  notice
specifying  the amount of original  issue  discount  (including  daily rates and
accrual  periods)  accrued on Outstanding  Securities as of the end of such year
and (ii)  such  other  specific  information  relating  to such  original  issue
discount as may then be relevant  under the Internal  Revenue  Code of 1986,  as
amended from time to time.

that, with respect to each series of Securities,  it will furnish or cause to be

60 days after (i) each record  date for the payment of interest on any  interest

reasonably  require of the names and  addresses of the holders of  Securities of
such  series  as of a date  not  more  than  15  days  prior  to the  time  such
information is furnished;  provided,  however,  that if the Trustee shall be the
Security registrar, such list shall not be required to be furnished.

     SECTION 6.02. Intentionally Omitted

     SECTION 6.03. Reports by the Corporation. (a) The Corporation covenants and
agrees to file with the Trustee within 30 days after the Corporation is required
to file the same with the  Securities  and  Exchange  Commission,  copies of the
annual reports and of the information, documents and other reports (or copies of
such portions of any of the foregoing as said  Commission  may from time to time
by rules and  regulations  prescribe)  which the  Corporation may be required to
file with  said  Commission  pursuant  to  section  13 or  section  15(d) of the
Securities  Exchange  Act of 1934,  as amended;  or, if the  Corporation  is not

exchange as may be prescribed  from time to time in such rules and  regulations;
delivery  of such  reports,  information  and  documents  to the  Trustee is for
informational  purposes  only  and  the  Trustees  receipt  of such  shall  not
constitute   constructive   notice  of  any   information   contained  there  or
determinable  from information  contained  therein  including the  Corporation's
compliance  with any of its  covenants  hereunder  (as to which the  Trustee  is
entitled to rely exclusively on Officers Certificates.)

prescribed from time to time by said  Commission,  such additional  information,

conditions and covenants  provided for in this Indenture as may be required from
time  to  time  by  such  rules  and  regulations;  delivery  of  such  reports,
information and documents to the Trustee is for informational  purposes only and
the Trustee's  receipt of such shall not constitute  constructive  notice of any
information  contained there or determinable from information contained therein,
including the Corporation's  compliance with any of its covenants  hereunder (as
to which the Trustee is entitled to rely exclusively on Officer's Certificates.)

     (c) The Corporation covenants and agrees to transmit by mail to all holders
of  Securities,  as the names and  addresses  of such  holders  appear  upon the
registry books of the Corporation,  within 30 days after the filing thereof with

to be filed by the Corporation pursuant to subsection (a) or (b) of this Section
6.03 as may be required by rules and regulations prescribed from time to time by
the Securities and Exchange Commission.

     SECTION 6.04. Reports by the Trustee. (a) On or before October 1, 1999, and

outstanding  hereunder,  the Trustee,  if required by the Trust Indenture Act of
1939, shall transmit to the Securityholders for which it is acting as Trustee, a
brief report dated as of the preceding September 1 with respect to:

          (1) its eligibility  under Section 8.09, and its  qualification  under
     Section 8.08,  or in lieu  thereof,  if to the best of its knowledge it has
     continued  to be eligible  and  qualified  under such  Sections,  a written
     statement to such effect; 

          (2) the  character  and  amount of any  advances  (and if the  Trustee
     elects so to state, the circumstances  surrounding the making thereof) made
     by the Trustee (as such) which  remain  unpaid on the date of such  report,

                                       21

<PAGE>

     and for the reimbursement of which it claims or may claim a lien or charge,
     prior to that of the  Securities  with  respect  to which it is  acting  as
     Trustee,  on any  property  or funds held or  collected  by it as  Trustee,
     except that the Trustee shall not be required (but may elect) to state such
     advances  if such  advances so  remaining  unpaid  aggregate  not more than
     one-half  of one  percent  of  the  principal  amount  of  such  Securities
     outstanding on the date of such report;

          (3) the amount,  interest  rate,  and the  maturity  date of all other
     indebtedness  owing by the  Corporation  (or by any other  obligor  on such
     Securities) to the Trustee in its individual capacity,  on the date of such
     report,  with a  brief  description  of any  property  held  as  collateral

     (6) of subsection (b) of Section 8.13;

          (4) the property and funds,  if any,  physically in the  possession of
     the Trustee, as such, at the date of such report;

          (5) any  additional  issue of  Securities  with respect to which it is
     acting as Trustee which it has not previously reported; and

          (6) any action taken by the Trustee in the  performance  of its duties
     under this Indenture which it has not previously  reported and which in its
     opinion materially  affects such Securities,  except action in respect of a
     default,  notice of which has been or is to be withheld by it in accordance
     with the provisions of Section 7.08.

          (b) The Trustee shall transmit to the Securityholders  with respect to
     which it is acting as Trustee, as hereinafter provided, a brief report with
     respect to the  character  and amount of any  advances  (and if the Trustee
     elects so to state, the circumstances  surrounding the making thereof) made
     by the  Trustee (as such),  since the date of the last  report  transmitted
     pursuant to the  provisions of subsection  (a) of this Section 6.04 (or, if
     no such report has yet been so transmitted,  since the date of execution of
     this  Indenture),  for the  reimbursement of which it claims or may claim a
     lien or charge prior to that of the Securities  with respect to which it is

                   EVENTS OF DEFAULT; REMEDIES OF THE TRUSTEE
                               AND SECURITYHOLDERS

     SECTION 7.01.  Events of Default;  Remedies.  The  occurrence of any of the
following events shall constitute an Event of Default  hereunder with respect to
any particular series of Securities:

          (a) default in the due and  punctual  payment of any  installments  of
     interest  upon any of the  Securities  of that  series as and when the same
     shall become due and payable and  continuance  of such default for a period
     of 30 days: or

          (b) default in the due and  punctual  payment of the  principal of (or
     premium,  if any, on) any of the  Securities of that series as and when the
     same shall become due and payable  either at maturity,  by  declaration  as
     authorized by this Indenture, or otherwise; or

          (c) failure on the part of the Corporation  duly to observe or perform
     any other of the covenants or agreements on the part of the Corporation set
     forth in the  Securities  of that series or in this  Indenture  (other than
     those set forth  exclusively in the terms of Securities of any series other
     than that series) continued for a period of sixty days after there has been
     given,  by registered or certified mail, to the Corporation by the Trustee,
     or to  the  Corporation  and  the  Trustee  by  the  holders  of  at  least
     thirty-three  percent in principal  amount of the Securities of that series
     at the time  outstanding,  a written  notice  specifying  such  failure and
     requiring the same to be remedied and stating that such notice is a "Notice
     of Default" hereunder; or

          (d) the entry of a decree or order by a court having  jurisdiction  in
     the  premises   granting  relief  in  respect  of  the  Corporation  in  an
     involuntary   case  under  the  Federal   Bankruptcy   Code  adjudging  the
     Corporation  a bankrupt or  insolvent,  or  approving  as properly  filed a
     petition seeking reorganization,  arrangement, adjustment or composition of

                                       23

<PAGE>

     or in respect of the Corporation  under the Federal  Bankruptcy Code or any
     other   applicable   Federal  or  State  law,  or  appointing  a  receiver,
     liquidator,  custodian,  assignee, trustee,  sequestrator (or other similar
     official) of the Corporation,  or of any substantial part of the respective
     properties  of either,  or ordering  the winding up or  liquidation  of the
     affairs of either, and the continuance of any such decree or order unstayed
     and in effect for a period of 120 days; or

          (e)  the   institution  by  the   Corporation  of  proceedings  to  be
     adjudicated a bankrupt or insolvent,  or the consent by the  Corporation to
     the institution of bankruptcy or insolvency  proceedings against it, or the
     filing by the  Corporation  of a  petition  or answer  or  consent  seeking
     reorganization  or relief  under the Federal  Bankruptcy  Code or any other
     applicable  Federal or State law, or the consent by the  Corporation to the
     filing  of  any  such  petition  or  to  the  appointment  of  a  receiver,
     liquidator,  custodian,  assignee, trustee,  sequestrator (or other similar
     official) of the Corporation,  or of any substantial part of the respective
     properties of either, or the making by the Corporation of an assignment for
     the benefit of creditors, or the admission by the Corporation in writing of
     its inability to pay its debts  generally as they become due, or the taking
     of corporate action by the Corporation in furtherance of any such action.

     In case one or more of the Events of  Default  specified  above  shall have
occurred and be continuing with respect to any particular  series of Securities,
then and in each  and  every  such  case,  unless  the  principal  of all of the
Securities of that series shall have already become due and payable,  either the
Trustee  or the  holders  of not less than  thirty-three  percent  in  aggregate
principal amount of the Securities of that series then outstanding hereunder, by
notice  in  writing  to  the  Corporation  (and  to  the  Trustee  if  given  by
Securityholders),  may  declare  the  principal  or,  in the case of  Discounted
Securities,  such amount of principal as may be provided for in such Securities,
of all the Securities of that series to be due and payable immediately, and upon
any such  declaration  the same shall  become and shall be  immediately  due and
payable,  anything  in  this  Indenture  or in the  Securities  of  that  series
contained to the contrary notwithstanding.  This provision,  however, is subject
to the  condition  that if, at any time after such  principal  or such amount of
principal,  as the case may be, shall have been so declared due and payable, and
before any  judgment or decree for the payment of the moneys due shall have been
obtained or entered as hereinafter provided,  the Corporation shall pay or shall
deposit with the Trustee a sum  sufficient  to pay all matured  installments  of
interest  upon all  Securities of that series and the principal of (and premium,
if any,  on) any and all  Securities  of that series which shall have become due

                                       24

<PAGE>

otherwise  than by  acceleration  (with  interest  on  overdue  installments  of
interest  (to the extent  that  payment of such  interest is  enforceable  under
applicable  law)  and on such  principal  (and  premium,  if any) at the rate of
interest  (or, in the case of Discounted  Securities,  at the Yield to Maturity)
borne  by such  Securities,  to the date of such  payment  or  deposit)  and the
expenses of the Trustee,  and any and all  defaults  under this  Indenture  with
respect to the Securities of the series,  other than the nonpayment of principal
of (and premium,  if any) and accrued  interest on the Securities of that series
which shall have become due by acceleration shall have been remedied-then and in
every such case the holder of a majority in  aggregate  principal  amount of the
Securities of that series then outstanding, by written notice to the Corporation
and  to the  Trustee,  may  waive  all  defaults  and  rescind  and  annul  such
declaration and its consequences; but no such waiver or rescission and annulment
shall  extend to or shall  affect any  subsequent  default,  or shall impair any
right consequent thereon.

     In case the Trustee  shall have  proceeded  to enforce any right under this
Indenture and such proceedings shall have been discontinued or abandoned for any
reason or shall have been determined adversely to the Trustee, then and in every
such case the  Corporation  and the Trustee  shall be restored  respectively  to
their  several  positions  and rights  hereunder,  and all rights,  remedies and
powers of the  Corporation  and the  Trustee  shall  continue  as though no such
proceeding had been taken.

     SECTION  7.02.  Payment  of  Securities  on  Default;  Suit  Therefor.  The
Corporation  covenants  that (a) in case default shall be made in the payment of
any installment of interest upon any of the Securities of any series as and when
the same shall become due and payable, and such default shall have continued for
a period of thirty days,  or (b) in case default shall be made in the payment of
the principal of (or premium, if any, on) any of the Securities of any series as
and when the same shall have become due and payable,  whether at maturity of the
Securities of that series or by declaration or otherwise,  then,  upon demand of
the Trustee,  the  Corporation  will pay to the Trustee,  for the benefit of the
holders of such Securities, the whole amount that then shall have become due and
payable on all such Securities for principal (and premium,  if any) or interest,
if any, with interest upon the overdue  principal (and premium,  if any) and (to
the extent that payment of such interest is enforceable  under  applicable  law)
upon the overdue  installments of interest at the rate of interest (or the Yield
to Maturity in the case of  Discounted  Securities)  borne by the  Securities of
that  series;  and,  in  addition  thereto,  such  further  amount  as  shall be
sufficient to cover the costs and expenses of collection,  including  reasonable
compensation to the Trustee, its agents, attorneys and counsel, and any expenses
or liabilities  incurred,  and all advances made, by the Trustee hereunder other
than through its negligence or willful misconduct.


                                       25

<PAGE>

     In case the Corporation  shall fail forthwith to pay such amounts upon such
demand,  the Trustee,  in its own name and as trustee of an express trust, shall
be entitled and empowered to institute any actions or  proceedings  at law or in
equity for the  collection of the sums so due and unpaid,  and may prosecute any
such action or proceeding to judgment or final decree,  and may enforce any such
judgment or final decree  against the  Corporation  or any other obligor on such
Securities and collect in the manner  provided by law out of the property of the
Corporation or any other obligor on such Securities wherever situated the moneys
adjudged or decreed to be payable.

     In case there shall be pending  proceedings  for the  bankruptcy or for the
reorganization  of the Corporation or any other obligor on the Securities of any
series under the Federal Bankruptcy Code or any other applicable law, or in case
a receiver,  custodian or trustee shall have been  appointed for the property of
the  Corporation or such other obligor,  or in the case of any similar  judicial
proceedings  relative to the Corporation or other obligor upon such  Securities,
or to the creditors or property of the  Corporation or such other  obligor,  the
Trustee,  irrespective of whether the principal of such Securities shall then be
due and  payable  as  therein  expressed  or by  declaration  or  otherwise  and
irrespective  of whether the Trustee shall have made any demand  pursuant to the
provisions  of  this  Section  7.02,   shall  be  entitled  and  empowered,   by
intervention  in such  proceedings  or  otherwise,  to file and prove a claim or
claims, for the whole amount of principal (and premium, if any) and interest, if
any owing and unpaid in respect of such Securities,  and in case of any judicial
proceedings,  to file such proofs of claim and other  papers or documents as may
be  necessary or advisable in order to have the claims of the Trustee and of the
holders of such Securities allowed in such judicial  proceedings relative to the
Corporation or any other obligor on such Securities,  its or their creditors, or
its or their  property,  and to collect and receive any moneys or other property
payable or deliverable on any such claims,  and to distribute the same after the
deduction of its charges and expenses; and any receiver,  custodian, assignee or
trustee in  bankruptcy  or  reorganization  is hereby  authorized by each of the
Securityholders to make such payments to the Trustee, and, in the event that the
Trustee  shall  consent  to  the  making  of  such  payments   directly  to  the
Securityholders,  to pay to the Trustee any amount due it for  compensation  and
expenses,  including  counsel  fees  incurred  by it  up to  the  date  of  such
distribution.

     All rights of action and of asserting claims under this Indenture, or under
any of the Securities,  may be enforced by the Trustee without the possession of
any  of the  Securities,  or the  production  thereof  in  any  trial  or  other
proceeding  relative  thereto,  and any  suit or  proceeding  instituted  by the
Trustee shall be brought in its own name as trustee of an express trust, and any
recovery  of  judgment  shall be for the  ratable  benefit of the holders of the

                                       26

<PAGE>

Securities in respect of which such judgment has been recovered.

     SECTION  7.03.  Application  of Moneys  Collected  by  Trustee.  Any moneys
collected by the Trustee shall be applied in the order following, at the date or
dates  fixed  by  the  Trustee  for  the  distribution  of  such  moneys,   upon
presentation  of the Securities in respect of which moneys have been  collected,
and stamping  thereon the payment,  if only  partially  paid, and upon surrender
thereof if fully paid:

          FIRST:  To the  payment  of  costs  and  expenses  of  collection  and
     reasonable compensation to the Trustee, its agents,  attorneys and counsel,

          SECOND: In case the principal of the outstanding Securities in respect
     of which  moneys  have  been  collected  shall not have  become  due and be

     order of the maturity of the  installments of such interest,  with interest
     (to the extent that such  interest has been  collected by the Trustee) upon
     the overdue  installments of interest at the rate of interest (or the Yield
     to Maturity in the case of Discounted Securities) borne by such Securities,
     such payments to be made ratably to the persons entitled thereto;

          THIRD: In case the principal of the outstanding  Securities in respect
     of which moneys have been  collected  shall have become due, by declaration

     with interest on the overdue  principal  (and premium,  if any) and (to the

     SECTION 7.04. Proceedings by Securityholders.  No holder of any Security of
any series shall have any right by virtue of or by availing of any  provision of
this  Indenture to institute any suit,  action or proceeding in equity or at law
upon or under or with  respect to this  Indenture  or for the  appointment  of a
receiver  or  trustee,  or for any other  remedy  hereunder,  unless such holder
previously  shall have given to a  Responsible  Officer of the  Trustee  written
notice of default and of the continuance thereof, as hereinbefore  provided, and
unless  also the  holders  of not less than  twenty-five  percent  in  aggregate
principal  amount of the Securities of that series then  outstanding  shall have
made  written  request  upon the  Trustee  to  institute  such  action,  suit or
proceeding  in its own name as Trustee  hereunder  and shall have offered to the
Trustee such  reasonable  security or  indemnity  as it may require  against the
costs,  expenses  and  liabilities  to be incurred  therein or thereby,  and the
Trustee  for sixty days after its receipt of such  notice,  request and offer of
indemnity, shall have neglected or refused to institute any such action, suit or
proceeding,  it being understood and intended, and being expressly covenanted by
the taker and holder of every Security with every other taker and holder and the
Trustee, that no one or more holders of Securities of that series shall have any
right in any manner  whatever by virtue of or by availing  of any  provision  of
this Indenture to affect,  disturb or prejudice the right of any other holder of
such  Securities,  or to obtain or seek to obtain priority over or preference to
any such  holder,  or to enforce any right under this  Indenture,  except in the
manner  herein  provided  and for the equal,  ratable and common  benefit of all
holders of Securities of that series.

     Notwithstanding  any other  provisions in this Indenture,  the right of any
holder of any Security to receive  payment of the principal of (and premium,  if
any) and interest,  if any, on such  Security,  on or after the  respective  due
dates  expressed in such Security,  or to institute suit for the  enforcement of
any such  payment on or after such  respective  dates  shall not be  impaired or
affected without the consent of such holder.

     SECTION  7.05.  Proceedings  by  Trustee.  In case of an Event  of  Default
hereunder the Trustee may in its  discretion  proceed to protect and enforce the
rights vested in it by this Indenture by such appropriate  judicial  proceedings
as the Trustee  shall deem  necessary to protect and enforce any of such rights,
either by suit in equity or by action at law or by  proceeding  in bankruptcy or
otherwise,  whether for the  specific  enforcement  of any covenant or agreement
contained in this  Indenture  or in aid of the exercise of any power  granted in
this  Indenture,  or to enforce any other legal or equitable right vested in the
Trustee by this Indenture or by law.

     SECTION 7.06. Remedies  Cumulative and Continuing.  All powers and remedies
given by this Article Seven to the Trustee or to the  Securityholders  shall, to

                                       28

<PAGE>

the extent  permitted  by law, be deemed  cumulative  and not  exclusive  of any
thereof or of any other  powers and  remedies  available  to the  Trustee or the
holders of the Securities,  by judicial proceedings or otherwise, to enforce the
performance  or observance of the  covenants  and  agreements  contained in this
Indenture,  and no delay or  omission  of the Trustee or of any holder of any of
the  Securities  to  exercise  any  right or  power  accruing  upon any  default
occurring and continuing as aforesaid  shall impair any such right or power,  or
shall  be  construed  to be a  waiver  of any such  default  or an  acquiescence
therein;  and, subject to the provisions of Section 7.04, every power and remedy
given by this Article  Seven or by law to the Trustee or to the  Securityholders
may be  exercised  from time to time and as often as may be deemed  expedient by
the Trustee or by the Securityholders.

     SECTION 7.07.  Direction of Proceedings  and Waiver of Defaults By Majority
of  Securityholders.  The holders of a majority in aggregate principal amount of
the  Securities of any series at the time  outstanding  determined in accordance
with Section 9.04 shall have the right to direct the time,  method, and place of
conducting  any  proceedings  for  any  remedy  available  to  the  Trustee,  or
exercising  any trust or power  conferred  on the  Trustee,  with respect to the
Securities of that series; provided, however, that (subject to the provisions of
Section  8.01) the  Trustee  shall  have the right to decline to follow any such
direction if the Trustee being advised by counsel  determines that the action or
proceeding so directed may not lawfully be taken or if the Trustee in good faith
by a trust committee of Responsible  Officers shall determine that the action or
proceedings so directed would involve the Trustee in personal  liability.  Prior
to any  declaration  accelerating  the maturity of the Securities of any series,
the  holders of a  majority  in  aggregate  principal  amount of the  Securities
determined  in  accordance  with  Section  9.04  of  that  series  at  the  time
outstanding  may on behalf of the holders of all Securities of that series waive
any past default or Event of Default  hereunder  and its  consequences  except a
default in the payment of the  principal of (or premium,  if any) or interest on
the Securities of that series. Upon any such waiver the Corporation, the Trustee
and the holders of such Securities  shall be restored to their former  positions
and rights  hereunder,  respectively;  but no such  waiver  shall  extend to any
subsequent or other  default or Event of Default or impair any right  consequent
thereon.  Whenever  any  default or Event of Default  hereunder  shall have been
waived as permitted by this Section 7.07, said default or Event of Default shall
for all  Purposes  of the  Securities  of such  series and this  Indenture  with
respect  to  such  Securities  be  deemed  to  have  been  cured  and  to be not
continuing.

     SECTION 7.08.  Notice of Defaults.  The Trustee  shall,  within ninety days
after the  occurrence of a default with respect to the Securities of any series,
mail to all  holders  of such  Securities,  as the names and  addresses  of such

                                       29

<PAGE>

holders  appear  upon the  registry  books  of the  Corporation,  notice  of all
defaults  actually  known to a Responsible  Officer of the Trustee,  unless such
defaults  shall have been  cured  before  the  giving of such  notice  (the term
"defaults"  for the purpose of this Section 7.08 being hereby  defined to be the
events  specified in clauses (a),  (b),  (c), (d) and (e) of Section  7.01,  not
including periods of grace, if any, provided for therein and irrespective of the
giving of the notice  specified in clause (c) of Section  7.01);  provided that,
except in the case of default in the payment of the principal of (or premium, if
any) or interest, if any, on any such Securities, the Trustee shall be protected
in  withholding  such notice if and so long as a trust  committee of Responsible
Officers in good faith  determines that the withholding of such notice is in the
interests of the holders of such Securities.

     SECTION  7.09.  Undertaking  to Pay Costs.  All  parties to this  Indenture
agree, and each holder of any Security by his acceptance thereof shall be deemed
to have agreed,  that any court may in its discretion  require,  in any suit for
the  enforcement  of any right or remedy  under this  Indenture,  or in any suit
against the Trustee for any action taken,  suffered or omitted by it as Trustee,
the filing by any party litigant in such suit of an undertaking to pay the costs
of such suit, and that such court may in its discretion assess reasonable costs,
including  reasonable  attorneys' fees, against any party litigant in such suit,
having due regard to the merits and good faith of the claims or defenses made by
such party litigant;  but the provisions of this Section 7.09 shall not apply to
any  suit   instituted   by  the  Trustee,   to  any  suit   instituted  by  any
Securityholder, or group of Securityholders,  holding in the aggregate more than
ten percent in principal amount of the Securities  outstanding of any series, or
to any suit instituted by any  Securityholder for the enforcement of the payment
of the  principal of (or premium,  if any) or interest,  if any, on any Security
against the Corporation on or after the due date expressed in such Security.

                                  ARTICLE EIGHT
                             CONCERNING THE TRUSTEE

     SECTION 8.01. Duties and  Responsibilities of Trustee.  With respect to the
Securities of any particular  series the Trustee,  prior to the occurrence of an
Event of Default  and after the  curing of all Events of Default  which may have
occurred,  undertakes  to  perform  such  duties  and only  such  duties  as are
specifically  set  forth in this  Indenture.  In case an Event  of  Default  has
occurred  (which has not been cured or waived) with respect to the Securities of
any  particular  series the Trustee shall exercise such of the rights and powers
vested  in it by this  Indenture,  and use the same  degree of care and skill in
their exercise,  as a prudent man would exercise or use under the  circumstances
in the conduct of his own affairs.


                                     30

<PAGE>

     No  provision of this  Indenture  shall be construed to relieve the Trustee
from liability for its own negligent action, its own negligent failure to act or
its own willful misconduct, except that

          (a) prior to the occurrence of an Event of Default with respect to the
     Securities of any particular  series and after the curing or waiving of all
     Events of Default with respect to the Securities of any  particular  series
     which may have occurred:

               (1) the duties and obligations of the Trustee with respect to the
          Securities  of such series shall be  determined  solely by the express
          provisions  of this  Indenture,  and the  Trustee  shall not be liable
          except  for the  performance  of such  duties and  obligations  as are
          specifically set forth in this Indenture,  and no implied covenants or
          obligations shall be read into this Indenture against the Trustee; and

               (2) in the  absence  of  willful  misconduct  on the  part of the
          Trustee,  the Trustee may  conclusively  rely,  as to the truth of the
          statements and the correctness of the opinions expressed therein, upon
          any  certificates or opinions  furnished to the Trustee and conforming
          to the  requirements of this  Indenture;  but, in the case of any such
          certificates   or  opinions   which  by  any   provision   hereof  are
          specifically  required to be  furnished  to the  Trustee,  the Trustee
          shall be under a duty to examine the same to determine  whether or not
          they  conform  to the  requirements  of this  Indenture  (but need not
          confirm or investigate the accuracy of any  mathematical  calculations
          or other facts stated therein);

          (b) the Trustee  shall not be liable for any error of judgment made in
     good faith by a Responsible  Officer or Officers of the Trustee,  unless it
     shall  be  proved  that the  Trustee  was  negligent  in  ascertaining  the
     pertinent facts; and

          (c) the Trustee  shall not be liable with respect to any action taken,
     suffered or omitted to be taken by it in good faith in accordance  with the
     direction of the holders of not less than a majority in principal amount of
     the Securities of any particular series at the time outstanding  determined
     as  provided  in Section  9.04  relating  to the time,  method and place of
     conducting  any  proceeding  for any remedy  available to the  Trustee,  or
     exercising  any  trust or power  conferred  upon the  Trustee,  under  this
     Indenture.

          (d) no provision of this Indenture shall require the Trustee to expend
     or risk its own funds or  otherwise  incur any  financial  liability in the
                                      
                                       31

<PAGE>

     performance  of any of its duties  hereunder,  or in the exercise of any of
     its rights or powers,  if it shall have  reasonable  grounds for  believing
     that  repayment  of such funds or adequate  indemnity  against such risk or
     liability is not reasonably assured to it.

          (e) Whether or not therein  expressly so provided,  every provision of
     this  Indenture  relating to the conduct or affecting  the  liability of or
     affording  protection to the Trustee shall be subject to the  provisions of
     this Section.

          SECTION 8.02.  Reliance on Documents,  Opinions,  etc.  Subject to the
     provisions of Section 8.01

          (a) the  Trustee  may rely and shall be  protected  in acting upon any
     resolution,  certificate,  statement,  instrument, opinion, report, notice,
     request,  consent, order, approval, bond, debenture,  coupon or other paper
     or document  (whether in its original or facsimile  form) believed by it to
     be genuine  and to have been  signed or  presented  by the proper  party or
     parties;

          (b)  any  request,  direction,  order  or  demand  of the  Corporation
     mentioned   herein  shall  be   sufficiently   evidenced  by  an  Officers'
     Certificate   (unless   other   evidence  in  respect   thereof  be  herein
     specifically prescribed);  and any resolution of the Board of Directors may
     be evidenced to the Trustee by a Board Resolution;

          (c) the Trustee may consult with counsel of its own  selection and any
     advice or 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  accordance  with such advice or Opinion of
     Counsel;

          (d) the Trustee  shall be under no  obligation  to exercise any of the
     rights or powers  vested in it by this  Indenture at the request,  order or
     direction of any of the Securityholders, pursuant to the provisions of this
     Indenture,  unless such  Securityholders  shall have offered to the Trustee
     reasonable  security  or  indemnity  satisfactory  to it against the costs,
     expenses and liabilities which may be incurred therein or thereby;

          (e) the Trustee shall not be liable for any action taken,  suffered or
     omitted by it in good faith and believed by it to be  authorized  or within
     the discretion or rights or powers conferred upon it by this Indenture;

          (f) prior to the occurrence of an Event of Default with respect to the
     Securities  of any  particular  series  hereunder  and after the  curing or
     waiving of all Events of Default  with  respect to the  Securities  of such

                                       32

<PAGE>

     series,  the Trustee shall not be bound to make any investigation  into the
     facts  or  matters  stated  in  any  resolution,   certificate,  statement,
     instrument,  opinion,  report, notice,  request,  consent, order, approval,
     bond,  debenture,  coupon or other paper or document,  unless  requested in
     writing to do so by the  holders of not less than a majority  in  principal
     amount  of the  Securities  of  such  series  then  outstanding;  provided,
     however, that if the payment within a reasonable time to the Trustee of the
     costs, expenses or liabilities likely to be incurred by it in the making of
     such  investigation  is, in the  opinion  of the  Trustee,  not  reasonably
     assured to the Trustee by the security  afforded to it by the terms of this
     Indenture,  the Trustee may require reasonable indemnity satisfactory to it
     against such expense or liability as a condition to so proceeding; and

          (g) the Trustee may execute any of the trusts or powers  hereunder  or
     perform any duties  hereunder  either  directly or by or through  agents or
     attorneys,  and the Trustee shall not be responsible  for any misconduct or
     negligence  on the part of any agent or attorney  appointed  by it with due
     care hereunder.

          (h) the  Trustee  shall not be deemed to have notice of any Default or
     Event of Default  unless a  Responsible  Officer of the  Trustee has actual
     knowledge  thereof or unless  written  notice of any event which is in fact
     such a default is received by the Trustee at the Corporate  Trust office of
     the Trustee,  and such notice references the Securities and this Indenture;
     and

          (i) the rights, privileges, protections, immunities and benefits given
     to the Trustee, including, without limitation, its right to be indemnified,
     are  extended to, and shall be  enforceable  by, the Trustee in each of its
     capacities  hereunder,  and to  each  agent,  custodian  and  other  Person
     employed to act hereunder.

     SECTION 8.03. No Responsibility  for Recitals,  etc. The recitals contained
herein  and  in  the  Securities   (except  in  the  Trustee's   certificate  of
authentication)  shall be taken as the  statements of the  Corporation,  and the
Trustee assumes no  responsibility  for the correctness of the same. The Trustee
makes no  representations as to the validity or sufficiency of this Indenture or
the Securities.  The Trustee shall not be accountable for the use or application
by  the  Corporation  of  any  Securities  or the  proceeds  of  any  Securities
authenticated  and delivered by the Trustee in conformity with the provisions of
this Indenture.

     SECTION 8.04.  Trustee,  Paying Agent or Registrar May Own Securities.  The
Trustee or any paying  agent or Security  registrar,  in its  individual  or any

                                       33

<PAGE>

other  capacity,  may become the owner or  pledgee of  Securities  with the same
rights it would have if it were not Trustee, paying agent or Security registrar.

     SECTION  8.05.  Moneys to Be Held in Trust.  Subject to the  provisions  of
Section  13.04,  all moneys  received by the Trustee or any paying  agent shall,
until used or applied as herein provided,  be held in trust for the purposes for
which they were  received.  Neither the  Trustee  nor any paying  agent shall be
under any liability for interest on any moneys  received by it hereunder  except
such as it may agree in writing with the Corporation to pay thereon.  So long as
no Event of Default shall have occurred and be continuing,  all interest allowed
on any such moneys shall be paid from time to time upon the written order of the
Corporation, signed by any one of the Chairman of the Board, the Chief Executive
Officer, the Vice Chairman, the President, a Vice President,  the Secretary,  an
Assistant Secretary, the Treasurer or an Assistant Treasurer of the Corporation.

     SECTION  8.06.  Compensation  and  Expenses  of  Trustee.  The  Corporation
covenants  and agrees to pay to the Trustee  from time to time,  and the Trustee
shall be entitled to, reasonable  compensation as shall be agreed upon from time
to time in writing (which shall not be limited by any provision of law in regard
to the compensation of a trustee of an express trust),  and the Corporation will
pay or  reimburse  the Trustee  upon its request  for all  reasonable  expenses,
disbursements  and advances  incurred or made by the Trustee in accordance  with
any of the provisions of this Indenture  (including the reasonable  compensation
and the  expenses  and  disbursements  of its  counsel  and of all  persons  not
regularly in its employ) except any such expense, disbursement or advance as may
arise from its negligence or willful misconduct.  The Corporation also covenants
to  indemnify  the  Trustee  and any  predecessor  Trustee  for,  and to hold it
harmless against, any loss, claim, damage, liability or expense incurred without
negligence  or willful  misconduct on the part of the Trustee and arising out of
or in  connection  with the  acceptance or  administration  of this trust or the
performance of its duties hereunder, including the reasonable costs and expenses
of  defending  itself  against  any  claim of  liability  in the  premises.  The
obligations of the Corporation under this Section 8.06 to compensate the Trustee
and to pay or reimburse  the Trustee for  expenses,  disbursements  and advances
shall constitute additional indebtedness hereunder. Such additional indebtedness
shall have a prior claim to that of the  Securities  upon all property and funds
held or  collected  by the Trustee as such,  except  funds held in trust for the
benefit of the holders of particular  Securities  The provisions of this section
shall survive the termination of this Indenture.

     SECTION 8.07. Officers Certificate as Evidence.  Subject to the provisions
of Section  8.01,  whenever  in the  administration  of the  provisions  of this
Indenture  the Trustee  shall deem it necessary  or  desirable  that a matter be

                                       34

<PAGE>

proved  or  established  prior to  taking,  suffering  or  omitting  any  action
hereunder,  such matter  (unless  other  evidence  in respect  thereof be herein
specifically prescribed) may, in the absence of negligence or willful misconduct
on the part of the Trustee,  be deemed to be conclusively proved and established
by an Officers' Certificate  delivered to the Trustee, and such Certificate,  in
the absence of negligence or bad faith on the part of the Trustee, shall be full
warrant to the Trustee for any action taken, suffered or omitted by it under the
provisions of this Indenture upon the faith thereof.

     SECTION 8.08.  Conflicting  Interest of Trustee.  (a) If the Trustee has or
shall acquire any  conflicting  interest  with respect to the  Securities of any
series, as defined in the Trust Indenture Act of 1939. It shall,  within 90 days
after ascertaining that it has such conflicting interest,  either eliminate such
conflicting  interest or resign with respect to the Securities of that series in
the manner and with the effect prescribed by the Trust Indenture Act of 1939.

     SECTION 8.09.  Eligibility of Trustee.  The Trustee  hereunder shall at all
times be a corporation organized and doing business under the laws of the United
States  or any  State  or  Territory  thereof  or of the  District  of  Columbia
authorized under such laws to exercise corporate trust powers, having a combined
capital and surplus of at least fifty million dollars and subject to supervision
or  examination  by  Federal,  State,  Territorial,   or  District  of  Columbia
authority. If such corporation publishes reports of condition at least annually,
pursuant to law or to the requirements of the aforesaid supervising or examining
authority,  then for the purposes of this Section 8.09, the combined capital and
surplus  of such  corporation  shall be deemed to be its  combined  capital  and
surplus as set forth in its most recent  report of  condition so  published.  In
case at any time the Trustee shall cease to be eligible in  accordance  with the
provisions of this Section 8.09,  the Trustee  shall resign  immediately  in the
manner and with the effect specified in Section 8.10.

     SECTION 8.10. Resignation or Removal of Trustee. (a) The Trustee may at any
time  resign  with  respect to the  Securities  of one or more  series by giving
written  notice of such  resignation  to the  Corporation  and by mailing notice
thereof to the holders of Securities  of such series at their  addresses as they
shall appear on the  registry  books of the  Corporation.  Upon  receiving  such
notice of  resignation,  the  Corporation  shall  promptly  appoint a  successor
trustee or trustees  with  respect to the  Securities  of such series by written
instrument, in duplicate,  executed by order of the Board of Directors, one copy
of which instrument shall be delivered to the resigning  Trustee and one copy to
each successor trustee. If no successor trustee shall have been so appointed and
have accepted  appointment within sixty days after the mailing of such notice of

                                       35

<PAGE>

resignation to the  Securityholders  of such series,  the resigning  Trustee may
petition any court of competent  jurisdiction for the appointment of a successor
trustee,  or any Securityholder who has been a bona fide holder of a Security or
Securities of such series for at least six months may, subject to the provisions
of  Section  7.09,  on behalf of  himself  and all  others  similarly  situated,
petition any such court for the appointment of a successor  trustee.  Such court
may thereupon,  after such notice,  if any, as it may deem proper and prescribe,
appoint a successor trustee.

          (b) In case at any time any of the following shall occur:

          (1) the Trustee shall fail to comply with the provisions of subsection
     (a) of Section 8.08 after written request therefor by the Corporation or by
     any  Securityholder  who has  been a bona  fide  holder  of a  Security  or
     Securities for at least six months, or

          (2) the Trustee  shall cease to be  eligible  in  accordance  with the
     provisions of Section 8.09 and shall fail to resign after  written  request
     therefor by the Corporation or by any such Securityholder, or

          (3) the Trustee shall become incapable of acting, or shall be adjudged
     a bankrupt or  insolvent,  or a receiver of the Trustee or of its  property
     shall be appointed,  or any public  officer shall take charge or control of
     the   Trustee  or  of  its   property   or  affairs   for  the  purpose  of
     rehabilitation, conservation or liquidation,

then, in any such case, the Corporation may remove the Trustee with respect to 
to all  Securities  and  appoint a  successor  trustee  or  trustees  by written
instrument, in duplicate,  executed by order of the Board of Directors, one copy
of which instrument shall be delivered to the Trustee so removed and one copy to
each  successor  trustee,  or,  subject to the  provisions of Section 7.09,  any
Securityholder  who has been a bona fide holder of a Security or Securities  for
at least six months may, on behalf of himself and all others similarly situated,
petition any court of competent  jurisdiction for the removal of the Trustee and
the  appointment of a successor  trustee or trustees.  Such court may thereupon,
after such  notice,  if any,  as it may deem  proper and  prescribe,  remove the
Trustee and appoint a successor trustee or trustees.

     (c)  The  holders  of a  majority  in  aggregate  principal  amount  of the
Securities  of any  series at the time  outstanding  may at any time  remove the
Trustee with respect to such series and nominate a successor trustee.

     (d) Any  resignation  or removal of the  Trustee and any  appointment  of a
successor  trustee  pursuant to any of the provisions of this Section 8.10 shall

                                       36

<PAGE>

become  effective upon  acceptance of  appointment  by the successor  trustee as
provided in Section 8.11.

     SECTION  8.11.  Acceptance  by  Successor  Trustee.  In  the  case  of  the
appointment hereunder of a successor trustee with respect to all Securities, any
successor  trustee so  appointed  as  provided  in Section  8.10 shall  execute,
acknowledge and deliver to the  Corporation  and to its  predecessor  trustee an
instrument accepting such appointment  hereunder,  and thereupon the resignation
or removal of the predecessor  trustee shall become effective and such successor
trustee,  without any further act, deed or conveyance,  shall become vested with
all the rights,  powers,  duties and obligations of its  predecessor  hereunder,
with like effect as if originally named as trustee herein: nevertheless,  on the
written  request of the  Corporation  or of the successor  trustee,  the trustee
ceasing to act shall,  upon  payment of any amounts  then due it pursuant to the
provisions of Section 8.06,  execute and deliver an instrument  transferring  to
such  successor  trustee  all the rights and powers of the trustee so ceasing to
act. In case of the appointment hereunder of a successor trustee with respect to
the  Securities  of one or more  (but  not all)  series,  the  Corporation,  the
predecessor trustee and each successor trustee with respect to the Securities of
one or more series shall  execute and deliver an indenture  supplemental  hereto
wherein each successor trustee shall accept such appointment and which (1) shall
contain  such  provisions  as shall be  necessary  or  desirable  to vest in, or
confirm  to,  each  successor  trustee  all  the  rights,   powers,  duties  and
obligations of the predecessor trustee with respect to the Securities of that or
those series to which the appointment of such successor trustee relates,  (2) if
the predecessor  trustee is not retiring with respect to all  Securities,  shall
contain  such  provisions  as shall be deemed  necessary or desirable to confirm
that all the rights,  powers,  duties and obligations of the predecessor trustee
with  respect  to the  Securities  of that  or  those  series  as to  which  the
predecessor  trustee  is  not  retiring  shall  continue  to be  vested  in  the
predecessor trustee, and (3) shall add to or change any of the provisions of the
Indenture as shall be necessary to provide for or facilitate the  administration
of the trusts  hereunder  by more than one  trustee,  it being  understood  that
nothing herein or in such supplemental  indenture shall constitute such trustees
co-trustees  of the same trust and that each such trustee  shall be trustee of a
trust or trusts hereunder  separate and apart from any trust or trusts hereunder
administered  by any other such trustee;  and upon the execution and delivery of
such  supplemental  indenture  the  resignation  or removal  of the  predecessor
trustee  shall  become  effective to the extent  provided  therein and each such
successor  trustee,  without any further act, deed or  conveyance,  shall become
vested with all the rights,  powers,  duties and  obligations of the predecessor
trustee  with  respect to the  Securities  of that or those  series to which the
appointment of such successor trustee relates; but, nevertheless, on the written

                                       37
<PAGE>

request of the Corporation or any successor  trustee,  such predecessor  trustee
shall,  upon  payment of any amounts  then due  pursuant to Section 8.06 hereof,
duly  assign,  transfer and deliver to such  successor  trustee all property and
money held by such predecessor  trustee hereunder with respect to the Securities
of that or those  series  to which the  appointment  of such  successor  trustee
relates.  Upon request of any such  successor  trustee,  the  Corporation  shall
execute any and all  instruments in writing in order more fully and certainly to
vest in and confirm to such successor trustee all such rights, powers and trusts
referred to in the two preceding  sentences.  Any trustee  ceasing to act shall,
nevertheless,  retain a prior claim upon all property or funds held or collected
by such trustee to secure any amounts then due it pursuant to the  provisions of
Section 8.06.

     No successor  trustee shall accept  appointment as provided in this Section
8.11  unless at the time of such  acceptance  such  successor  trustee  shall be
qualified under the provisions of Section 8.08 and eligible under the provisions
of Section 8.09.

     Upon  acceptance of appointment by a successor  trustee as provided in this
Section  8.11,  the  Corporation  shall mail  notice of the  succession  of such
trustee  hereunder to all holders of  Securities  of the series  affected as the
names  and  addresses  of such  holders  appear  on the  registry  books  of the
Corporation.  If the  Corporation  fails to mail such  notice in the  prescribed
manner  within 30 days after the  acceptance  of  appointment  by the  successor
trustee,  the  successor  trustee  shall  cause such  notice to be mailed at the
expense of the Corporation.

     SECTION 8.12.  Succession by Merger,  etc. Any  corporation  into which the
Trustee may be merged or converted or with which it may be consolidated,  or any
corporation resulting from any merger,  conversion or consolidation to which the
Trustee shall be a party or any corporation  succeeding to all or  substantially
all of the corporate  trust  business of the Trustee,  shall be the successor of
the  Trustee  hereunder  without  the  execution  or  filing of any paper or any
further act on the part of any of the parties hereto.

     In case at the time such  successor  to the  Trustee  shall  succeed to the
trusts  created  by  this  Indenture  any  of the  Securities  shall  have  been
authenticated but not delivered, any such successor to the Trustee may adopt the
certificate  of  authentication  of any  predecessor  trustee,  and deliver such
Securities  so  authenticated;  and in case at that  time any of the  Securities
shall not have been authenticated, any successor to the Trustee may authenticate
such Securities  either in the name of any predecessor  hereunder or in the name
of the successor trustee; and in all such cases such certificates shall have the
full force which it is anywhere in the Securities or in this Indenture  provided
that the  certificate  of the Trustee shall have;  provided,  however,  that the

                                     38

<PAGE>

right to adopt the certificate of authentication  of any predecessor  Trustee or
authenticate  Securities in the name of any predecessor Trustee shall apply only
to its successor or successors by merger, conversion or consolidation.

     SECTION 8.13. Trustees  Application for Instructions from The Corporation.
The Trustee may apply in writing,  sent by  registered  or certified  mail,  for
instructions from the Corporation regarding actions to be taken or omitted under
the  Indenture,  and as part of the  application,  the Trustee may set forth the
action proposed to be taken or omitted by it, and the date on and/or after which
such action  shall be taken or such  omission  shall be  effective.  The Trustee
shall not be liable  for any action  taken by, or  omission  of, the  Trustee in
accordance  with a proposal  included in such  application  on or after the date
specified in such application  (which date shall not be less than three Business
Days  after the date any  officer  of the  corporation  actually  receives  such
application,  unless any such  officer  shall have  consented  in writing to any
earlier date) unless prior to taking any such action (or the  effective  date in
the case of an omission),  the Trustee shall have received written  instructions
in response to such application specifying the action to be taken or omitted.

 
                                  ARTICLE NINE
                         CONCERNING THE SECURITYHOLDERS

     SECTION 9.01. Action by  Securityholders.  Whenever in this Indenture it is
provided  that the  holders of a specified  percentage  in  aggregate  principal
amount of the Securities of any or all series may take any action (including the
making of any demand or request, the giving of any notice,  consent or waiver or
the  taking of any other  action)  the fact that at the time of taking  any such
action the  holders of such  specified  percentage  have  joined  therein may be
evidenced,  subject to Section  10.07,  (a) by any  instrument  or any number of
instruments of similar tenor executed by holders of such Securities in person or
by agent or proxy  appointed in writing,  or (b) by the record of the holders of
such  Securities  voting in favor  thereof  at any  meeting  of  holders of such
Securities  duly called and held in  accordance  with the  provisions of Article
Ten, or (c) by a  combination  of such  instrument or  instruments  and any such
record of such a meeting of holders of such Securities.

     SECTION  9.02.  Proof  of  Execution  by  Securityholders.  Subject  to the
provisions  of Sections  8.01,  8.02 and 10.05,  proof of the  execution  of any
instruments  by a  Securityholder  or his agent or proxy shall be  sufficient if
made  in  accordance  with  such  reasonable  rules  and  regulations  as may be
prescribed  by the  Trustee or in such  manner as shall be  satisfactory  to the
Trustee.  The ownership of Securities  shall be proved by the registry  books of

                                       39

<PAGE>

the Corporation or by a certificate of the Security registrar.

     The record of any  Securityholders'  meeting  shall be proved in the manner
provided in Section 10.06.

     SECTION 9.03. Who Are Deemed Absolute Owners. The Corporation, the Trustee,
any paying  agent and any Security  registrar  may deem the person in whose name
any Securities shall be registered upon the registry books of the Corporation to
be, and may treat such person as, the absolute  owner of such Security  (whether
or not such Security  shall be overdue) for the purpose of receiving  payment of
or on account of the principal of (and premium, if any) and interest, if any, on
such Security and for all other  purposes;  and neither the  Corporation nor the
Trustee nor any paying agent nor any Security registrar shall be affected by any
notice to the  contrary.  All such  payments  so made to any holder for the time
being,  or upon his order shall be valid,  and, to the extent of the sum or sums
so paid,  effective to satisfy and discharge  the  liability for moneys  payable
upon any such Security.

     No holder of any  beneficial  interest in any global  Security  held on its
behalf by a Depositary  shall have any rights under this  Indenture with respect
to such global Security,  and such Depositary may be treated by the Corporation,
the Trustee, any paying agent and any agent of the Corporation or the Trustee as
the owner of such  global  Security  for all  purposes  whatsoever.  None of the
Corporation,  the Trustee,  any paying agent or any Security registrar will have
any  responsibility  or liability  for any aspect of the records  relating to or
payments made on account of beneficial  ownership interests of a global Security
or for  maintaining,  supervising  or  reviewing  any  records  related  to such
beneficial ownership interests.

     SECTION 9.04.  Corporation-Owned  Securities  Disregarded.  In  determining
whether the holders of the requisite  aggregate  principal  amount of Securities
have  concurred  in any  direction,  consent  or waiver  under  this  Indenture,
Securities  which  are owned by the  Corporation  or any  other  obligor  on the
Securities or by any person directly or indirectly  controlling or controlled by
or under direct or indirect  common  control with the  Corporation  or any other
obligor on the Securities  shall be disregarded and deemed not to be outstanding
for the purpose of any such  determination;  provided  that for the  purposes of
determining  whether  the  Trustee  shall be  protected  in  relying on any such
direction,  consent or waiver only Securities which a Responsible Officer of the
Trustee actually knows are so owned shall be so disregarded. Securities so owned
which have been  pledged in good faith may be  regarded as  outstanding  for the
purposes of this Section 9.04 if the pledgee shall establish to the satisfaction
of the Trustee the pledgee's  right to vote such Securities and that the pledgee

                                       40

<PAGE>

is not a person  directly or  indirectly  controlling  or controlled by or under
direct  or  indirect  common  control  with the  Corporation  or any such  other
obligor.  In the case of a dispute as to such right, any decision by the Trustee
taken upon the advice of counsel shall be full protection to the Trustee.

     SECTION 9.05.  Revocation of Consents;  Future Holders  Bound.  At any time
prior to (but not after) the  evidencing to the Trustee,  as provided in Section
9.01, of the taking of any action by the holders of the  percentage in aggregate
principal  amount of the  Securities  specified in this  Indenture in connection
with such action,  any holder of a Security the serial  number of which is shown
by the  evidence  to be  included  in the  Securities  the holders of which have
consented to such action may, by filing  written  notice with the Trustee at its
principal  office and upon proof of holding as provided in Section 9.02,  revoke
such action so far as  concerns  such  Security.  Except as  aforesaid  any such
action taken by the holder of any Security  shall be conclusive and binding upon
such holder and upon all future  holders and owners of such  Security and of any
Security issued in exchange or substitution  therefore,  irrespective of whether
or not any notation in regard thereto is made upon such Security.

                                   ARTICLE TEN

The Corporation,  when authorized by a resolution of the Board of Directors, and
the  Trustee  may from time to time and at any time enter into an  indenture  or

          (b) to add to the covenants of the Corporation such further covenants,

     supplemental  indenture may provide for a particular  period of grace after

     matters or questions arising under this Indenture which shall not adversely
     affect the interest of the holders of the Securities;

the holders of any of the  Securities at the time  outstanding,  notwithstanding
any of the provisions of Section 11.02.

less than 66 2/3% in aggregate  principal amount of the Securities of all series
affected  by such  supplemental  indenture  (voting  as one  class)  at the time
outstanding,  the  Corporation,  when authorized by a resolution of the Board of
Directors,  and the  Trustee may from time to time and at any time enter into an
indenture  or  indentures  supplemental  hereto  for the  purpose  of adding any
provisions to or changing in any manner or eliminating  any of the provisions of

any Security, or reduce the rate or change the method to be used in establishing
the rate or extend  the time of  payment  of  interest  thereon,  or reduce  the
principal  amount  thereof,  or reduce any premium  payable upon the  redemption
thereof,  or reduce the amount of the  principal of a Discounted  Security  that
would be due and payable  upon a  declaration  of  acceleration  of the maturity
thereof  pursuant to Section 7.01,  or make the principal  thereof or premium or
interest  thereon  payable in any coin or currency  other than that  provided in
such Securities, without the consent of the holder of each Security so affected,


                                       45

or (ii) reduce the aforesaid percentage of Securities,  the holders of which are
required to consent to any such supplemental  indenture,  without the consent of
the  holders  of all  Securities  of the series  affected  then  outstanding.  A
supplemental  indenture  which  changes  or  eliminates  any  covenant  or other
provision of this  Indenture  which has expressly  been included  solely for the
benefit of one or more  particular  series of Securities,  or which modifies the
rights of the holders of Securities of such series with respect to such covenant
or other  provision,  shall be  deemed  not to  affect  the  rights  under  this
Indenture of the holders of Securities of any other series.

     Upon the  request of the  Corporation,  accompanied  by a Board  Resolution
authorizing  the  execution  of any such  supplemental  indenture,  and upon the
filing  with the  Trustee  of  evidence  of the  consent of  Securityholders  as
aforesaid,  the Trustee shall join with the Corporation in the execution of such
supplemental  indenture unless such supplemental indenture affects the Trustee's
own rights,  duties or immunities  under this  Indenture or otherwise,  in which
case the Trustee may in its  discretion,  but shall not be  obligated  to, enter
into such supplemental indenture.

     It shall not be necessary for the consent of the Securityholders under this
Section  11.02 to  approve  the  particular  form of any  proposed  supplemental
indenture,  but it  shall  be  sufficient  if such  consent  shall  approve  the
substance thereof.

     SECTION 11.03.  Compliance with Trust Indenture Act; Effect of Supplemental
Indenture.  Any supplemental  indenture  executed  pursuant to the provisions of
this Article  Eleven shall comply with the Trust  Indenture Act of 1939, as then
in effect.  Upon the  execution of any  supplemental  indenture  pursuant to the
provisions of this Article  Eleven,  this Indenture shall be and be deemed to be
modified  and  amended  in  accordance  therewith  and  the  respective  rights,
limitations of rights,  obligations,  duties and immunities under this Indenture
of the Trustee,  the  Corporation  and the holders of  Securities  of the series
affected  shall  thereafter  be  determined,  exercised  and enforced  hereunder
subject in all respects to such  modifications  and amendments and all the terms
and conditions of any such  supplemental  indenture shall be and be deemed to be
part of the terms and conditions of this Indenture for any and all purposes.

     SECTION  11.04.  Notation  on  Securities.   Securities  authenticated  and
delivered  after the  execution of any  supplemental  indenture  pursuant to the
provisions  of this Article  Eleven may bear a notation in form  approved by the
Trustee as to any matter  provided for in such  supplemental  indenture.  If the
Corporation shall so determine, new Securities so modified as to conform, in the
opinion of the Trustee and the Board of Directors,  to any  modification of this
  
                                     46

<PAGE>

Indenture  contained  in any such  supplemental  indenture,  may be prepared and
executed by the  Corporation,  authenticated  by the Trustee  and  delivered  in
exchange for the Securities then outstanding.

     SECTION  11.05.  Evidence of  Compliance  of  Supplemental  Indenture to Be
Furnished Trustee.  The Trustee,  subject to the provisions of Sections 8.01 and
8.02,  shall  receive  an  Officers'  Certificate  and an  Opinion of Counsel as
conclusive  evidence that any supplemental  indenture  executed  pursuant hereto
complies with the requirements of this Article Eleven.

                                 ARTICLE TWELVE
                         CONSOLIDATION, MERGER AND SALE

     SECTION 12.01. Corporation May Consolidate, etc., on Certain Terms. Nothing
contained  in this  Indenture  or in any of the  Securities  shall  prevent  any
consolidation or merger of the Corporation with or into any other corporation or
corporations  (whether or not affiliated  with the  Corporation),  or successive
consolidations  or  mergers  in  which  the  Corporation  or  its  successor  or
successors shall be a party or parties,  or shall prevent any sale or conveyance
of all or  substantially  all  the  property  of the  Corporation  to any  other
corporation  (whether or not  affiliated  with the  Corporation)  authorized  to
acquire and operate the same;  provided,  however,  and the  Corporation  hereby
covenants  and  agrees,  that  upon  any  such  consolidation,  merger,  sale or
conveyance,  the due and punctual  payment of the principal of (and premium,  if
any) and interest,  if any, on all of the Securities,  according to their tenor,
and the due and punctual  performance and observance of all of the covenants and
conditions  of this  Indenture  to be  performed  by the  Corporation,  shall be
expressly assumed by supplemental indenture satisfactory in form to the Trustee,
executed and  delivered to the Trustee,  by the  corporation  (if other than the
Corporation) formed by such  consolidation,  or into which the Corporation shall
have been merged, or by the corporation which shall have acquired such property.

     SECTION 12.02. Successor Corporation to Be Substituted. In case of any such
consolidation,  merger,  sale or  conveyance  and  upon  the  assumption  by the
successor corporation, by supplemental indenture,  executed and delivered to the
Trustee and satisfactory in form to the Trustee, of the due and punctual payment
of the  principal of (and premium,  if any) and interest,  if any, on all of the
Securities  and the due and punctual  performance  of all of the  covenants  and
conditions of this Indenture to be performed by the Corporation,  such successor
corporation  shall succeed to and be substituted for the  Corporation,  with the
same effect as if it had been named herein as the  Corporation.  Such  successor
corporation  thereupon  may cause to be signed,  and may issue either in its own
name or in the  name  of  Constellation  Energy  Group,  Inc.  any or all of the
Securities  issuable  hereunder which  theretofore shall not have been signed by

                                       47

<PAGE>

the  Corporation  and  delivered  to the  Trustee;  and,  upon the order of such
successor  corporation  instead of the Corporation and subject to all the terms,
conditions  and  limitations  in this  Indenture  prescribed,  the Trustee shall
authenticate  and shall deliver any Securities  which previously shall have been
signed and  delivered  by the  officers  of the  Corporation  to the Trustee for
authentication,  and any Securities which such successor corporation  thereafter
shall cause to be signed and delivered to the Trustee for that purpose.  All the
Securities of a particular  series so issued shall in all respects have the same
legal rank and benefit  under this  Indenture as the  Securities  of such series
theretofore or thereafter  issued in accordance with the terms of this Indenture
as though all of such  Securities  had been issued at the date of the  execution
hereof.

     Nothing  contained  in this  Indenture  or in any of the  Securities  shall
prevent the Corporation from merging into itself any other corporation  (whether
or not affiliated  with the  Corporation)  or acquiring by purchase or otherwise
all or any  part  of the  property  of any  other  corporation  (whether  or not
affiliated with the Corporation),  provided that,  immediately after such merger
or acquisition,  the  Corporation  shall not be in default in the performance or
observance of any of the terms, covenants and conditions of this Indenture to be
kept or performed by it.

     SECTION  12.03.  Opinion of Counsel to Be Given To  Trustee.  The  Trustee,
subject  to  Sections  8.01 and 8.02,  shall  receive  an  Opinion of Counsel as
conclusive evidence that any such consolidation,  merger, sale or conveyance and
any such assumption complies with the provisions of this Article.

     SECTION  13.01.  Discharge of  Indenture.  When (a) the  Corporation  shall
deliver to the Trustee for cancellation all Securities theretofore authenticated
(other than any Securities  which shall have been destroyed,  lost or stolen and
which shall have been  replaced  or paid as  provided  in Section  3.05) and not
theretofore  cancelled,  or (b) all the Securities not theretofore  delivered to
the Trustee for cancellation shall have become due and payable,  or are by their
terms to  become  due and  payable  within  one year and the  Corporation  shall
deposit with the Trustee or any paying agent, in trust,  funds sufficient to pay
at maturity all of the Securities  (other than any  Securities  which shall have
been mutilated,  destroyed, lost or stolen and which shall have been replaced or
paid as provided in Section 3.05) not  theretofore  delivered to the Trustee for
cancellation,  including principal (and premium,  if any) and interest,  if any,
due or to become  due to such date of  maturity,  but  excluding,  however,  the
amount of any moneys for the payment of the principal of (and  premium,  if any)

or  interest,  if any, on the  Securities  (1)  theretofore  deposited  with the
Trustee or any paying agent and repaid by the Trustee or any paying agent to the
Corporation in accordance  with the provisions of Section 13.04,  or (2) paid to
any State or to the District of Columbia  pursuant to its unclaimed  property or
similar laws, and if in either case the  Corporation  shall also pay or cause to
be paid all other sums payable hereunder by the Corporation, then this Indenture
shall  cease  to be of  further  effect,  and  the  Trustee,  on  demand  of the
Corporation accompanied by an Officers' Certificate and an Opinion of Counsel as
required by Section 16.05 and at the cost and expense of the Corporation,  shall
execute proper  instruments  acknowledging  satisfaction of and discharging this
Indenture. The Corporation,  however, hereby agrees to reimburse the Trustee for
any costs or expenses thereafter reasonably and properly incurred by the Trustee
in connection with this Indenture or the Securities.

     SECTION 13.02.  Deposited Moneys to Be Held in Trust by Trustee. All moneys
deposited  with the Trustee or any paying agent  pursuant to Section 13.01 shall
be held in trust and applied by it to the  payment,  either  directly or through
any paying agent  (including the Corporation if acting as its own paying agent),
to the holders of the particular Securities for the payment of which such moneys
have been deposited with the Trustee,  or any paying agent,  of all sums due and
to become due thereon for principal (and premium, if any) and interest.

     SECTION 13.03. Paying Agent to Repay Moneys Held. Upon the satisfaction and
discharge  of this  Indenture  all moneys  then held by any paying  agent of the
Securities  (other than the Trustee) shall,  upon demand of the Corporation,  be
repaid to it or paid to the Trustee,  and  thereupon  such paying agent shall be
released from all further liability with respect to such moneys.

     SECTION 13.04.  Return of Unclaimed  Moneys.  Any moneys  deposited with or
paid to the Trustee  for payment of the  principal  of (or  premium,  if any) or
interest on Securities of any series and not applied but remaining  unclaimed by
the  holders  of such  Securities  for two years  after the date upon  which the
principal of (or premium,  if any) or interest on such  Securities,  as the case
may be,  shall have  become  due and  payable,  shall on written  request of the
Corporation be repaid to the  Corporation by the Trustee;  and the holder of any
of such Securities shall thereafter look only to the Corporation for any payment
which such holder may be entitled to collect.  Any  reference  to the Trustee in
this Section 13.04 shall be deemed to also include any entity  designated by the
Corporation  with  the  consent  of the  Trustee  to act as its  agent  for  the
performance of all or any of its duties under this Section.

recourse for the payment of the principal of (or premium, if any) or interest on
any Security,  or for any claim based  thereon or otherwise in respect  thereof,
and no  recourse  under or upon any  obligation,  covenant or  agreement  of the
Corporation  in  this  Indenture  or in any  supplemental  indenture,  or in any
Security,  or because of the creation of any indebtedness  represented  thereby,
shall be had against any  incorporator,  stockholder,  officer or  director,  as
such,  past,  present  or  future,  of  the  Corporation  or  of  any  successor
corporation,  either  directly  or  through  the  Corporation  or any  successor
corporation,  whether by virtue of any constitution,  statute or rule of law, or
by the enforcement of any assessment or penalty or otherwise; it being expressly
understood that all such liability is hereby  expressly waived and released as a
condition of, and as a  consideration  for, the execution of this  Indenture and
the issue of the Securities.

                                 ARTICLE FIFTEEN
                                  SINKING FUNDS

     SECTION  15.01.  General.  Any redemption of Securities of any series under
any sinking fund as required or permitted  by the terms of any  Securities  duly
issued  pursuant to this Indenture  shall be made in accordance  with such terms
and this Article Fifteen.

     The  Securities  of any series may be subject to  redemption  pursuant to a
sinking fund, in whole or in part, as set forth in
the form of Security for such series.

     The minimum amount of any sinking fund payment provided for by the terms of
Securities  of any series is herein  referred to as a  "mandatory  sinking  fund
payment," and any payment in excess of such minimum  amount  provided for by the
terms of Securities of any series is herein referred to as an "optional  sinking
fund  payment." If provided for by the terms of  Securities  of any series,  the
cash amount of any sinking  fund payment may be subject to reduction as provided

the  election of the  Corporation  pursuant to the terms of such  Securities  or

                                       50

through the application of permitted  optional sinking fund payments pursuant to
the terms of such Securities, in each case in satisfaction of all or any part of
any sinking fund payment with respect to the Securities of such series  required
to be made pursuant to the terms of such Securities as provided for by the terms
of such  series;  provided  that such  Securities  have not been  previously  so
credited. Such Securities shall be received and credited for such purpose by the
Trustee at the  redemption  price  specified in such  Securities  for redemption
through  operation  of the  sinking  fund and the  amount of such  sinking  fund
payment shall be reduced accordingly.

     SECTION  15.03.  Redemption of Securities  for Sinking Fund.  Not less than
sixty days prior to each sinking fund payment date for any series of Securities,
the Corporation will deliver to the Trustee an Officers' Certificate  specifying
the amount of the next ensuing  sinking fund payment for that series pursuant to
the terms of that series, the portion thereof, if any, which is to be by payment
of cash and the portion thereof,  if any, which is to be satisfied by delivering
and  crediting  Securities of that series as permitted by Section 15.02 and will
also deliver to the Trustee any Securities to be so delivered if not theretofore
delivered.  The Trustee  shall select the  Securities  to be redeemed  upon such
sinking  fund  payment  date in the manner  specified  in Section 4.03 and cause
notice of the redemption  thereof to be given in the manner  provided in Section
4.04.  Such notice having been duly given,  the  redemption  of such  Securities
shall be made upon the terms and in the manner stated in Sections 4.05 and 4.06.

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 April 15 and October 15 next preceding the May
1 and  November 1 Interest  Payment  Dates;  provided,  however,  that  interest
payable at Stated  Maturity or, if  applicable,  upon  redemption or repurchase,

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

this Note is presented to the Bank in time for the Bank to make such payments in
such funds in accordance with its normal procedures.

                       FORM OF FIXED-RATE MEDIUM-TERM NOTE


                                    (REVERSE)

                        CONSTELLATION ENERGY GROUP, INC.

                           MEDIUM-TERM NOTE, SERIES A
                                  (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 A (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 of repurchase, but no later than 5:00 p.m. New York

                                     - 4 -

<PAGE>

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

                                     - 5 -

<PAGE>

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.

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
Spread Multiplier, as the case may be, specified above. Interest will be payable
on each  Interest  Payment  Date and at Stated  Maturity or upon  redemption  or
repurchase.  Each  payment  of  interest  payable  at  Stated  Maturity  or,  if
applicable,  upon  redemption  or  repurchase  shall  include  interest  to, but
excluding the date of Stated Maturity or redemption or repurchase.  In the event
this Note is issued  between a Record Date (the date 15  calendar  days prior to
each Interest  Payment Date whether or not such day shall be a Business Day) and
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  __________,  1999 (the  "Indenture"),  by and between the Company and The
Bank of New York, a corporation  duly  organized and existing  under the laws of

includes any successor Trustee under the Indenture).

     Pursuant to the provisions of the  Indenture,  the Company will maintain an
agency at The Bank of New York in The City of New York,  New York (the  "Bank"),
or at such  other  agencies  as may from time to time be  designated,  where the
Notes may be presented for payment,  for  registration of transfer and exchange,
and where notices or demands to, or upon, the Company may be served.

     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 A (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

                                     - 5 -

<PAGE>

except as specified herein, on each Interest 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

                                     - 6 -

<PAGE>

Yield (calculated as described 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.


                                     - 7 -

<PAGE>

         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:

     (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.

     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

                                     - 9 -

<PAGE>

four  major  money  center  banks  in The  City  of  New  York  selected  by the
Calculation  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

                                     - 10 -

<PAGE>

Spread  and/or  Spread  Multiplier,  as the  case  may be,  for the  immediately
preceding interest reset period.

     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

                                     - 11 -

<PAGE>

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 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

                                     - 12 -

<PAGE>

of the heading  "Determination of LIBOR" above, and (ii) such Business 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
Baltimore,  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

                                     - 13 -

<PAGE>

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 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  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

March 24, 1999



Constellation Energy Group, Inc.
c/o David A. Brune
39 W. Lexington Street
Baltimore, Maryland 21201

Gentlemen:

     This opinion is provided in connection with the registration statement (the
"Registration  Statement")  being  filed by  Constellation  Energy  Group,  Inc.
(formerly  Constellation Energy Corporation)  ("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 A (the "Notes").  The Registration  Statement also acts as a
post-effective  amendment to a  registration  statement  filed by  Constellation
Energy Corporation with the SEC under the Securities Act of 1933.

     Pursuant to an  Agreement  and Plan of Share  Exchange  dated  February 19,
1999, between Constellation Energy and Baltimore Gas and Electric Company (BGE),
upon the occurrence of certain events all of the outstanding common stock of BGE
will be exchanged,  on a one-for-one  basis,  for common stock of  Constellation
Energy. In anticipation of the consummation of the share exchange, Constellation
Energy  is  filing  this  Registration  Statement  in  regard to its Notes to be
offered upon effectiveness of the share exchange.

     I am an attorney in the Corporate Unit of the legal  department of BGE. BGE
is a shareholder of Constellation Energy, and Constellation Energy has requested
that I provide this opinion.  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 current  articles of  incorporation of
Constellation Energy, as amended, and a form of amended and restated articles of
incorporation of Constellation  Energy (the "Charter") to be filed and effective
upon   consummation  of  the  share   exchange;   (2)  the  current  by-laws  of
Constellation  Energy,  and a form of  by-laws  of  Constellation  Energy  to be
adopted effective upon  consummation of the share exchange (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.


<PAGE>

     This opinion is subject to: (1) the share exchange  becoming  effective and
the  filing  with  the  appropriate  State  authority,   and  effectiveness  of,
Constellation  Energy's  Charter;  (2)  the  proper  adoption  by  Constellation
Energy's  Board of  Directors  of the By-Laws;  (3) the  Registration  Statement
becoming  effective under the Securities Act of 1933; (4) the proper  execution,
authentication,  and delivery of the Notes upon  receipt of the  purchase  price
pursuant to the Purchase  Agreement;  and (5) 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,


                                                              /s/ Donna M. Levy

                      

                                                                   Exhibit 23(b)







                     
                       CONSENT OF INDEPENDENT ACCOUNTANTS

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

                                POWER OF ATTORNEY


     KNOW ALL MEN BY THESE PRESENTS, that the undersigned directors and officers
of Constellation Energy Group, Inc. hereby constitute and appoint David A. Brune
and Thomas E. Ruszin,  Jr. and each of them their true and lawful  attorneys and
agents to do any and all acts and things and to  execute,  in their name any and
all  instruments  which said  attorneys  and  agents,  or any of them,  may deem
necessary or advisable to enable said  corporation to comply with the Securities

Securities  and Exchange  Commission in respect  thereof in connection  with the
