     PROPOSAL NO. 1 -- APPROVAL OF THE SHARE EXCHANGE AND FORMATION OF THE
                                HOLDING COMPANY

             SUMMARY QUESTIONS AND ANSWERS ABOUT THE SHARE EXCHANGE

     The following questions and answers briefly describe the share exchange
and formation of the holding company, but may not include all the information
about the proposal that is important to you. For more complete information,
please read this entire proxy statement and prospectus, including the exhibits,
and the other documents to which we refer. See "Where You Can Get More
Information" on page 38.


WHY IS BGE PROPOSING TO FORM A HOLDING COMPANY?

We believe that a holding company structure will provide the financial and
regulatory flexibility needed to effectively compete in the unregulated energy
business while continuing to operate our regulated utility business.
Constellation Energy will be able to raise capital for its unregulated
businesses in the public markets, which is an efficient and cost effective way
to finance businesses. BGE is prohibited from doing this under Maryland public
utility law. See "Reasons for Forming a Holding Company" on page 6.


WILL I HAVE TO PHYSICALLY EXCHANGE MY BGE COMMON STOCK CERTIFICATES FOR
CONSTELLATION ENERGY COMMON STOCK CERTIFICATES?

No. Your BGE common stock certificates will automatically represent an equal
number of shares of Constellation Energy common stock when the share exchange
is complete. See "Exchange of BGE Common Stock Certificates" on page 17.


WILL I CONTINUE TO RECEIVE DIVIDENDS?

After the share exchange, you will receive dividends from Constellation Energy,
when declared by its Board of Directors. It is expected that Constellation
Energy common stock dividends will initially be paid at the same rate and at
the same time as BGE paid them. See "Risk Factors" on page 5.


WILL MY RIGHTS AS A SHAREHOLDER BE AFFECTED?

Yes. Constellation Energy common shareholders' rights will be governed by
Constellation Energy's charter and by-laws (forms of which are included as
Appendices B and C, respectively, to this document). For a discussion of the
differences between BGE's and Constellation Energy's charter and by-laws, see
"Comparative Shareholder Rights" on page 12. BGE's preference stock is not
being exchanged.


ARE THERE FEDERAL INCOME TAX CONSEQUENCES TO BGE'S COMMON SHAREHOLDERS?

No. No income, gain or loss will be recognized under federal income tax laws as
a result of the share exchange, and your tax basis in the common stock you own
will stay the same. See "Material Federal Income Tax Consequences" on page 14.


HOW WILL MY PARTICIPATION IN BGE'S SHAREHOLDER INVESTMENT PLAN BE AFFECTED?

All shares of BGE common stock you hold under this plan will be automatically
exchanged for an equal number of shares of Constellation Energy common stock.
Following the share exchange, the plan will provide for transactions in
Constellation Energy common stock. See "BGE Stock Plans" on page 15.

SUMMARY QUESTIONS AND ANSWERS
ABOUT THE SHARE EXCHANGE
<PAGE>

HOW WILL BGE'S EMPLOYEE SAVINGS PLAN AND OTHER EMPLOYEE BENEFIT PLANS BE
AFFECTED?

BGE common stock held in BGE's Employee Savings Plan, Manager Long-Term
Incentive Plan and the Long-Term Incentive Plan will automatically be exchanged
for an equal number of shares of Constellation Energy common stock. Benefits
under BGE's other employee benefit plans, such as the pension plan and health
plans, will not change as a result of the share exchange because they do not
issue common stock. See "BGE Stock Plans" on page 15.


WHAT WILL BE THE BUSINESS OF CONSTELLATION ENERGY?

After the share exchange, Constellation Energy will own the stock of two
subsidiaries, BGE and Constellation Enterprises, Inc. BGE will continue to
operate the regulated utility business, and Constellation Enterprises will
continue to operate the unregulated businesses. See "Constellation Energy's
Business" on page 7.

WHO WILL MANAGE CONSTELLATION ENERGY?

All 15 directors of BGE will be the directors of Constellation Energy
immediately after the share exchange. Christian H. Poindexter will be Chairman
of the Board, President and Chief Executive Officer of Constellation Energy.
The other executive officers of Constellation Energy are expected to come from
BGE. See "Directors and Executive Officers of Constellation Energy and BGE" on
page 10.


HAVE ALL REGULATORY APPROVALS BEEN OBTAINED?

Most of the approvals have been received. The Federal Energy Regulatory
Commission and the Pennsylvania Public Utility Commission have approved the
share exchange. We expect to receive Nuclear Energy Regulatory Commission
approval by April 1, 1999. We do not anticipate any problems with obtaining
that approval. No Maryland Public Service Commission approval is required. See
"Regulatory Approvals" on page 16.


WHEN WILL CONSTELLATION ENERGY BECOME THE HOLDING COMPANY?

We expect to form the holding company on or about April 30, 1999, assuming all
conditions are met by then. See "Conditions to Share Exchange" on page 16.


WHAT VOTE IS REQUIRED TO APPROVE THE SHARE EXCHANGE?

The share exchange must be approved by the affirmative vote of the holders of
two-thirds of the outstanding shares of BGE common stock. BGE's directors and
executive officers combined beneficially own less than 1% of the outstanding
common stock of BGE.

SUMMARY QUESTIONS AND ANSWERS
ABOUT THE SHARE EXCHANGE
<PAGE>

WILL BGE PREFERENCE STOCK OR DEBT BE EXCHANGED?

No. BGE preference stock will not be exchanged and will remain outstanding
shares of BGE. BGE's outstanding debt will remain the obligation of BGE and
will not become an obligation of Constellation Energy. See "Preference Stock of
BGE" on page 18.


CAN I GET FAIR VALUE FOR MY BGE COMMON STOCK IF I OBJECT TO THE SHARE EXCHANGE?
 

No. Under Maryland law since BGE's stock was traded on the New York Stock
Exchange on February 18, 1999, the record date for determining eligibility to
vote on the share exchange, BGE's common shareholders cannot get fair value
(cash) for their stock if they object to the share exchange. Since BGE's
preference stock is not being exchanged, these holders also do not have fair
value rights. See "Obtaining Fair Value For BGE Common Stock" on page 18.


WHO CAN I CONTACT IF I HAVE ANY QUESTIONS?

The principal executive offices of both BGE and Constellation Energy are
located at 39 W. Lexington Street, Baltimore, MD 21201. The telephone number
for both companies is: 410-234-5000. In addition, BGE's Shareholder Services
unit is available to answer your questions. You may contact them at the
appropriate number listed below:

                                 RISK FACTORS


UNREGULATED BUSINESSES MAY INVOLVE MORE RISK
     Constellation Energy's unregulated subsidiaries intend to engage mostly in
energy-related businesses. In the future, assuming the generation segment of
our utility business is deregulated, we expect that unregulated businesses,
which would include generation, will contribute more to Constellation Energy's
overall earnings than BGE's regulated utility operations. However, the
unregulated businesses are very competitive and may have different, and perhaps
greater, investment risks and earnings fluctuations than the regulated utility
business of BGE. As is the case now, we will not be able to recover any losses
incurred by these businesses in BGE's utility rates and such losses could
adversely affect the market value of Constellation Energy.


AMOUNT OF DIVIDENDS ON CONSTELLATION ENERGY COMMON STOCK CANNOT BE ASSURED

     Constellation Energy does not now, nor will it initially after the share
exchange, directly conduct any business from which it will earn revenues or
produce cash. Constellation Energy plans to pay its expenses by billing its
subsidiaries for services it performs for them. Constellation Energy plans to
pay dividends on its common stock from dividends it receives from its
subsidiaries. The amount of the subsidiaries' dividends to Constellation Energy
depend upon the future earnings, financial condition, capital requirements and
regulation of those companies. While we currently anticipate that dividends
received by Constellation Energy from its subsidiaries will be sufficient to
enable it to pay dividends on its common stock, there can be no guarantee of
the amount of any quarterly dividends paid, if at all.

                                                                    RISK FACTORS
<PAGE>

ANTI-TAKEOVER PROVISIONS OF MARYLAND LAW AND CONSTELLATION ENERGY'S CHARTER AND
   BY-LAWS

     Some provisions of Maryland law and Constellation Energy's charter and
by-laws could discourage transactions that involve an actual or threatened
change of control of Constellation Energy. These include provisions such as
changes to the by-laws, advance notice of matters to be brought before a
meeting of shareholders and removal of directors. Because Constellation Energy
will not be subject to the same regulatory oversight afforded BGE's regulated
utility operations, it may be more vulnerable than BGE to unsolicited attempts
to acquire control. The provisions in Constellation Energy's charter and
by-laws are designed to compensate for this vulnerability by improving the
ability of Constellation Energy's Board of Directors to prevent transactions
that, in the Board's opinion, do not maximize long-term shareholder value or
are otherwise not in the best interest of shareholders. They may, however,
delay, discourage or prevent an unsolicited takeover attempt that a shareholder
might believe is in his interest. This could include takeover attempts that
would pay a premium over the market price for Constellation Energy common
stock.


                     REASONS FOR FORMING A HOLDING COMPANY


GENERAL

     BGE's traditional regulated business of providing electricity and natural
gas to customers in its service territory is being opened to competition, as
discussed in the next section. Partially in response to this competitive
environment, BGE has increased its unregulated, energy-related business.
However, under Maryland public utility law, BGE cannot raise capital for its
unregulated businesses. Since we anticipate that in the future the capital
needs of the unregulated businesses will be greater than that of BGE, the
holding company structure will separate the operation of the regulated business
from the unregulated businesses, allowing Constellation Energy to raise capital
for its unregulated businesses in the public markets, which is more efficient
and cost effective. In addition, the capital structure of each unregulated
business may be tailored to suit its individual business. These factors will
enhance Constellation Energy's competitiveness.

     A holding company structure is common for companies engaged in multiple
lines of business and is preferred by the investment community because it is
easier to analyze and value individual lines of business. A holding company
structure also makes it easier for regulators to assure that there is no
cross-subsidization of costs or transfer of business risk from unregulated to
regulated lines of business. Finally, a holding company structure provides the
regulated utility legal protection from the results of unregulated business
activities.


COMPETITION

     In recent years, federal and state initiatives have promoted the
development of competition in the sale of electricity and gas. In general,
these initiatives have sought to unbundle the integrated services that electric
and gas utilities have traditionally provided and to enable customers to
purchase electricity and gas directly from suppliers other than their local
utilities.

     With the passage of the Energy Policy Act of 1992, there has been a
significant increase in the level of competition for the generation and sale of
electricity at wholesale. The Energy Policy Act reduces barriers to market
entry for companies that wish to build, own and operate electric generating
facilities, and it also promotes competition by authorizing the Federal Energy
Regulatory Commission (FERC) to require electric utilities to provide
transmission service to other companies for wholesale power transactions. In
1996, the FERC issued Order 888 requiring electric utilities to make the
utility transmission systems available to wholesale sellers and buyers of
electric energy on a non-discriminatory basis. This means that other companies
may use BGE's transmission system to transport electricity to their customers.


                                        
                                       6
 
REASONS FOR FORMING A HOLDING COMPANY

<PAGE>

     Also, BGE is a member of the Pennsylvania-New Jersey-Maryland
interconnection which is an independent system operator that controls and
operates electric transmission facilities in this region as an integrated
system on a non-discriminatory basis. The interconnection provides open access
to the transmission facilities of all of its members based on tariffs filed
with the FERC.

     At the retail level, many states are implementing "retail access" programs
giving electric retail customers the option to choose among energy suppliers.
Maryland is considering offering a retail access program beginning in July
2000. See "Constellation Energy's Business -- BGE" below for a further
discussion.

     Similar events have already occurred in the gas utility industry. Two
decades ago, the price of gas was regulated from the original producer and
supplier through the ultimate end-user. Currently, there is no regulation over
the wholesale price of natural gas as a commodity, and the regulation of
interstate transmission at the federal level has been reduced. All BGE
industrial and commercial gas customers have the option to purchase gas from
other suppliers. A pilot program is currently in place allowing BGE's
residential gas customers the option to purchase gas from other suppliers,
including BGE Home Products & Services, Inc. Currently, this program is open to
over 50,000 residential customers and in November 1999, will be open to all
residential customers.


                        CONSTELLATION ENERGY'S BUSINESS


CONSTELLATION ENERGY GROUP, INC.
     The name of the holding company will be Constellation Energy Group, Inc.
All of its outstanding shares of common stock are currently owned by BGE. These
shares will be cancelled when the share exchange is completed.

     Following the share exchange, Constellation Energy will own all the
outstanding BGE and Constellation Enterprises common stock. Constellation
Energy will finance its expenses, investment in its subsidiaries and various
transactions that it may undertake from:

     o dividends it receives from its subsidiaries,

     o loans from financial institutions,

     o sales of equity and debt securities, and

     o payments from subsidiaries for services it performs on their behalf.

     Constellation Energy will not be subject to regulation by the Maryland
Public Service Commission, the Federal Energy Regulatory Commission, the
Nuclear Regulatory Commission or the Pennsylvania Public Utility Commission,
except to the extent that the rules or orders of these agencies impose
restrictions on Constellation Energy's relationship with BGE or BGE's
relationship with Constellation Energy's other subsidiaries.

     Constellation Energy will be a "public utility holding company" under the
Public Utility Holding Company Act of 1935. However, Constellation Energy
expects to obtain an exemption from most of the provisions of that law. See
"Exemption from Public Utility Holding Company Act of 1935" on page 17.


BGE

     BGE's utility business includes both electric and gas businesses. The
electric business generates, purchases, and sells electricity. The gas business
purchases, transports, and sells natural gas. The focus of these activities is
serving customers in BGE's service territory.

                                                 CONSTELLATION ENERGY'S BUSINESS
<PAGE>

     BGE also owns two-thirds of the outstanding capital stock, including
one-half of the voting stock, of Safe Harbor Water Power Corporation. Safe
Harbor produces hydroelectric power on the Susquehanna River at Safe Harbor,
Pennsylvania.

     BGE furnishes electric and gas retail service in the City of Baltimore and
in all or part of ten counties in Central Maryland. The electric service
territory includes an area of approximately 2,300 square miles with an
estimated population of 2.6 million. The gas service territory includes an area
of more than 600 square miles with an estimated population of 2.0 million.
There are no municipal or cooperative wholesale customers within the service
territory. The two units at Calvert Cliffs nuclear power plant are the
principal generating facilities. Following the share exchange, BGE will
continue to directly operate its utility business.

     BGE's utility business is subject to regulation by the Maryland Public
Service Commission (Maryland PSC), the FERC, the Nuclear Regulatory Commission
and other governmental agencies. The Maryland PSC regulates BGE's electric and
gas rates and the issuance of its securities. The FERC regulates BGE's rates
for sales at wholesale, rates for electric transmission and interconnections
with other utilities and short-term borrowings. The Nuclear Regulatory
Commission regulates the Calvert Cliffs nuclear power plant.

     On July 1, 1998, BGE and all other Maryland investor-owned electric
utilities filed with the Maryland PSC their individual proposals for the
transition from a regulated electric supply system to one where generation is
priced based on a competitive retail electric market. BGE's plan proposed that:
 

   o all customers would be able to choose other suppliers or BGE's service,

   o BGE would guarantee its service at rates frozen until July 2002. Prices
     would then be adjusted for inflation until the transition is complete, but
     not beyond 2008,

   o customers who choose an alternate supplier would receive a shopping
     credit. This credit would reduce their BGE bill by the market value of
     capacity, energy, and other services that BGE no longer provides those
     customers,

   o BGE would attempt to reduce potentially stranded investments by lowering
     operating costs and applying all earnings in excess of its authorized rate
     of return to accelerate the depreciation of generation assets. This would
     lower the generation asset book values to their competitive market values
     thereby reducing any potentially stranded investment,

   o market value of generation assets would be determined by annual
     independent appraisals beginning in 2002 and continuing through the
     transition period,

   o when the difference between the book value and market value of generation
     assets is within 10%, the transition period would end and a non-bypassable
     surcharge would be applied to customers' bills to recover the remaining
     stranded investments over a two-to-three year period, and

   o net regulatory assets and nuclear decommissioning costs would continue to
     be collected from customers through the regulated transmission and
     distribution business.

     All the other parties participating in the BGE proceeding before the
Maryland PSC filed positions in response to our proposal on December 22, 1998.
The Maryland PSC will hold hearings to examine our proposal and the counter
proposals of the other parties in the spring of 1999. In the meantime,
settlement negotiations are ongoing. Absent a settlement, the Maryland PSC is
scheduled to issue an order by October 1, 1999.

                                   DIVIDENDS

     After the share exchange, former BGE common shareholders, who will be
Constellation Energy common shareholders, will receive dividends on
Constellation Energy common stock when and if declared by the Board of
Directors of Constellation Energy. Dividends on Constellation Energy common
stock are expected to be paid initially at the same rate and at the same time
as BGE paid them. However, there can be no guarantee that Constellation Energy
will pay dividends at this rate, if at all. The most recent dividend paid by
BGE on its common stock was $.42 per share, which was paid on January 4, 1999.
Constellation Energy may issue preferred stock, which would have preferential
dividend rights over its common stock.

                          CONSTELLATION ENERGY AND BGE

CONSTELLATION ENERGY
BEFORE THE SHARE EXCHANGE. The following persons currently hold the offices
indicated with Constellation Energy:

     Charles W. Shivery- Director, Chairman of the Board and President
     David A. Brune- Director, Vice President and Secretary
     Thomas E. Ruszin, Jr.- Director, Treasurer

     Until the share exchange, these individuals will serve as the only
directors and officers of Constellation Energy. Effective with the share
exchange, they will resign as directors of Constellation Energy. Messrs. Brune
and Ruszin will continue as officers of Constellation Energy. Mr. Shivery will
resign as an officer of Constellation Energy but will remain an officer of
Constellation Power Source, Inc.

AFTER THE SHARE EXCHANGE. All 15 directors of BGE will be the directors of
Constellation Energy after the share exchange. The number of directors of
Constellation Energy is currently set at 15, and each will have a one year
term. That number, however, is expected to be increased after the share
exchange to 18 by the Board of Constellation Energy, which has the power
generally to fill vacancies and increase the number of directors. Any new
directors are expected to be elected from the directors of the current
subsidiaries of BGE.

     Christian H. Poindexter will be the Chairman of the Board, President and
Chief Executive Officer of Constellation Energy. The other executive officers
of Constellation Energy are expected to come from BGE.


BGE

                      CONSTELLATION ENERGY CAPITAL STOCK


COMMON STOCK
     GENERAL. Constellation Energy's charter authorizes it to issue 250,000,000
shares of common stock.

     When issued in the share exchange, Constellation Energy's common stock
will be fully paid and nonassessable.

     Constellation Energy's common shareholders are not entitled to any
preemptive, redemption or conversion rights. Constellation Energy may purchase
or otherwise acquire outstanding shares of its common stock.

     VOTING RIGHTS. Constellation Energy's common shareholders are entitled to
one vote for each share. There are no cumulative voting rights.

     DIVIDENDS. Subject to any prior rights of Constellation Energy's preferred
stock (if any are issued), Constellation Energy's common shareholders are
entitled to dividends if and when declared by the Board of Directors.

     LIQUIDATION RIGHTS. Subject to any prior rights of Constellation Energy's
preferred stock (if any are issued), upon liquidation, dissolution or winding
up, any remaining net assets of Constellation Energy would be evenly
distributed to its common shareholders.


PREFERRED STOCK

     Constellation Energy's charter authorizes it to issue 25,000,000 shares of
preferred stock. Each share will have up to 1 vote per share. The Board of
Directors is authorized from time to time to issue the preferred stock in any
series, and to specify the:

     o number of shares,

     o designation,

     o preferences and relative participating, optional or other rights,

     o convertibility, redemption, put and sinking fund provisions, and

     o qualifications or restrictions

of each series, to the full extent permitted by Maryland law. There will be no
restrictions on repurchases or redemptions of preferred stock, even if
Constellation Energy has not paid any dividends owed or sinking fund
installments. Preferred shareholders are not entitled to preemptive rights.
Constellation Energy will not issue preferred stock as a defensive takeover
mechanism without prior shareholder approval and will not afford preferred
shareholders voting rights superior (including votes per share) to common
shareholders.

<PAGE>

TRANSFER AGENTS AND REGISTRARS

     Constellation Energy will be a transfer agent and registrar, and Harris
Trust and Savings Bank will be a co-transfer agent and registrar, for
Constellation Energy common stock. Constellation Energy's address is:
Shareholder Services, P.O. Box 1642, Baltimore, MD 21203-1642. Harris Trust's
address is: Shareholder Services Division, 11th floor, 311 West Monroe Street,
Chicago, IL 60606. Constellation Energy will be the transfer agent and
registrar for its preferred stock if any shares are issued.


                        COMPARATIVE SHAREHOLDER RIGHTS

     After the share exchange, BGE common shareholders will become
Constellation Energy common shareholders, and their rights will be governed by
Constellation Energy's charter and by-laws rather than BGE's charter and
by-laws. Constellation Energy's charter and by-laws differ from BGE's in
certain respects. The differences in Constellation Energy's charter and by-laws
reflect the: (1) removal of obsolete and unnecessary provisions; (2) inclusion
of provisions that provide flexibility to operate in a competitive market; and
(3) inclusion of provisions that provide additional financing flexibility.
Approval of the share exchange will also be considered approval and
ratification of Constellation Energy's charter and by-laws. For more
information, please refer to the forms of the charter and by-laws that are
included as appendices B and C.

     The table below compares some of the rights provided to BGE and
Constellation Energy shareholders under their respective charters and by-laws,
under Securities and Exchange Commission (SEC) rules, and Maryland law:

AUTHORIZED SHARES

     BGE. BGE has authorized:
      o 175,000,000 shares of common stock,
      o 1,000,000 shares of preferred stock, and
      o 6,500,000 shares of preference stock.

     CONSTELLATION ENERGY. Constellation Energy has authorized:
      o 250,000,000 shares of common stock, and

COMPARATIVE SHAREHOLDER RIGHTS
<PAGE>

PREFERRED STOCK

   BGE. BGE's charter authorizes both preferred and preference stock. The
   charter specifies, among other things:
      o the number of votes per share (4 votes per share for preferred and 1
        vote per share for preference),
      o matters preferred and preference shareholders may vote on,
      o a limit on the amount of dividends that are payable on the preferred
        stock, and
      o certain financial tests that must be met before the preferred or
        preference stock may be issued.

   The charter allows BGE's Board of Directors to specify the other rights and
   terms of both types of stock, such as redemption and convertibility
   provisions.

     CONSTELLATION ENERGY. Constellation Energy's charter authorizes only
preferred stock. It specifies that the preferred stock will have no more than
one vote per share, as determined by the Board. The Board will determine the
other terms of any preferred stock at the time of issuance. Constellation
Energy will not issue preferred stock as a defensive takeover mechanism without
prior shareholder approval and will not afford preferred shareholders voting
rights superior (including votes per share) to common shareholders.


VOTE REQUIRED TO PASS CERTAIN MATTERS

     BGE. The approval of two-thirds of all the votes entitled to be cast must
be received to approve charter amendments and certain extraordinary matters
such as mergers, share exchanges and the sale of substantially all of BGE's
assets.

     CONSTELLATION ENERGY. The approval of two-thirds of all the votes entitled
to be cast must be received to approve charter amendments and certain
extraordinary matters such as mergers, share exchanges and the sale of
substantially all of Constellation Energy's assets. However, the Board may
authorize that such a matter be approved by a majority of all the votes
entitled to be cast.


REMOVAL OF DIRECTORS

     BGE. Under BGE's by-laws, the shareholders, at any meeting duly called and
at which a quorum is present, may remove any director from office by a majority
vote.

     CONSTELLATION ENERGY. Under Constellation Energy's charter, the
shareholders, at any meeting duly called and at which a quorum is present, may
remove any director from office for cause by a majority vote.


AMENDING THE BY-LAWS

     BGE. BGE's by-laws may be amended or repealed, and new by-laws adopted, by
a majority vote of the Board of Directors or the common shareholders.

     CONSTELLATION ENERGY. Constellation Energy's by-laws may be amended or
repealed, and new by-laws adopted by a majority vote of the Board of Directors
or by a two-thirds vote of the common shareholders.


ADVANCE NOTICE PROVISION

     BGE. Neither BGE's charter nor its by-laws include a provision with
respect to advance notice of shareholder proposals or director nominations.
Under SEC rules, shareholder proposals must be received at least 120 days prior
to the anniversary of the date that the prior year's proxy statement was mailed
to shareholders in order to be considered for inclusion in the proxy statement.
Other proposals sought to be presented at the shareholders' meeting must be
received at least 45 days prior to the anniversary of the date that the prior
year's proxy statement was mailed to shareholders.

                                                  COMPARATIVE SHAREHOLDER RIGHTS
<PAGE>

     CONSTELLATION ENERGY. The SEC rule requiring 120 days advance notice of
shareholder proposals sought to be included in the proxy statement will also
apply to Constellation Energy. In addition, under Constellation Energy's
by-laws, written notice of a proposal to be presented by any shareholder at the
shareholders' meeting (including nominations for director) must be received by
the Secretary of Constellation Energy at its principal executive office not
less than 75 days prior to the anniversary of the date the proxy statement was
mailed for the prior year's annual meeting (if the share exchange is approved,
the anniversary of the mail date for Constellation Energy's first annual
meeting will be March 5, 2000). If the proposal is not timely received, the
shareholder may not present it at the annual meeting. See "Submission of
Shareholder Proposals for Next Year" on page 38. The additional 30 day time
period has been added to ensure that Constellation Energy has sufficient time
to inform all shareholders, in the proxy statement, of the matter sought to be
presented at the meeting.


MARYLAND LAW

     Certain provisions of Maryland law provide enhanced rights to
shareholders, including the right of holders of at least 25% of the outstanding
common stock to call a special meeting of shareholders for any purpose and the
right to take action by way of unanimous written consent without calling a
special meeting of shareholders.

     However, certain other provisions of Maryland law may have the effect of
discouraging persons from acquiring large blocks of a Maryland corporation's
stock and/or delaying or preventing a change of control of a Maryland
corporation. Under certain circumstances, these provisions could have the
effect of, among other things:

   o reducing or eliminating the voting power of a 20% or more shareholder,

   o prohibiting a 10% or more shareholder from engaging in a business
     combination with a Maryland corporation for five years following the
     acquisition of the 10% stake (a "freezeout" provision), and

   o requiring a premium payment for shares purchased in a two-step
     acquisition.

     Friendly mergers and other business combinations would not be affected by
these provisions. However, a Maryland corporation may opt out of the provisions
by providing so in its charter or by-laws. An amendment adopted for the purpose
of opting out of the freeze-out provision does not become effective until 18
months after its adoption. Neither BGE nor Constellation Energy have opted out
of the provisions.


                   MATERIAL FEDERAL INCOME TAX CONSEQUENCES

     BGE and Constellation Energy have received an opinion from Miller &
Chevalier Chartered, their special tax counsel, regarding material federal
income tax consequences of the share exchange. Miller & Chevalier's opinion is
based on certain representations of BGE and is summarized below:

   o no income, gain or loss will be recognized by a BGE common shareholder
     solely upon the exchange of the holder's BGE common stock for
     Constellation Energy common stock;

   o no income, gain or loss will be recognized on the share exchange by
     holders of outstanding shares of BGE preference stock with respect to
     their shares because they will not participate in the share exchange and
     will keep their BGE preference stock;

   o the aggregate tax basis of shares of Constellation Energy common stock
     received by a former BGE common shareholder in the share exchange will
     equal their tax basis in the shares of BGE common stock exchanged. The
     holding period for the Constellation Energy common stock received will
     include


                                        
                                       14
 
MATERIAL FEDERAL INCOME TAX CONSEQUENCES
<PAGE>

     the holding period for the BGE common stock exchanged to the extent that
     such shares were held as capital assets at the time the share exchange
     occurred;

   o no gain or loss will be recognized by Constellation Energy or BGE on
     account of the share exchange or the issuance of shares of Constellation
     Energy common stock to the former BGE common shareholders pursuant to the
     Agreement and Plan of Share Exchange; and

   o the share exchange will not result in the termination of the existence of
     the affiliated group of corporations of which BGE has been the common
     parent, and Constellation Energy will be included in such affiliated group
     of corporations of which Constellation Energy will become the new common
     parent.

     Former BGE common shareholders are required under Treasury Regulation
1.351-3(a) to attach to their income tax returns for 1999 the following facts
relating to the share exchange: the cost basis of BGE common stock exchanged
with Constellation Energy, the number of shares exchanged and the fair market
value at the date of the exchange of the Constellation Energy common stock
received. We will provide a statement to shareholders that will indicate the
fair market value per share of Constellation Energy common shares received in
the exchange and the date of the exchange, to assist shareholders with the
required tax filing.

     This United States federal income tax discussion is based upon current law
and may not apply for certain taxpayers subject to special treatment under the
federal income tax laws (for example, foreign corporations and individuals who
are not citizens or residents of the United States). This is not intended to be
a comprehensive discussion of all possible federal income tax consequences of
the share exchange. Furthermore, this proxy statement and prospectus does not
provide any information regarding the tax consequences of the share exchange
under the tax laws of any state or any local or foreign jurisdiction. We urge
BGE common shareholders to consult their own tax advisors with respect to
specific tax consequences of the share exchange.


                              ACCOUNTING TREATMENT

     The consolidated assets and liabilities of Constellation Energy and its
subsidiaries immediately after the share exchange will be the same as the
consolidated assets and liabilities of BGE and its subsidiaries immediately
before the share exchange. Constellation Energy, on an unconsolidated basis,
will record its investment in BGE and in the subsidiaries transferred by BGE at
their existing values. After the share exchange, Constellation Energy will
become the owner of the BGE common stock. This change in ownership has no
accounting effect on BGE. The transfer of the ownership of BGE's subsidiaries
to Constellation Energy will reduce BGE's assets and retained earnings by an
amount equal to BGE's investments in the subsidiaries.


                                BGE STOCK PLANS

     Under the Agreement and Plan of Share Exchange, all shares of BGE common
stock (including uncertificated whole and fractional shares) held under BGE's
Shareholder Investment Plan, the Employee Savings Plan, the Manager Long-Term
Incentive Plan and the Long-Term Incentive Plan will be automatically exchanged
for an equal number of Constellation Energy common stock shares. The plans will
be amended to provide for future transactions in Constellation Energy common
stock instead of BGE common stock.


                       MARKET VALUE OF BGE COMMON STOCK

     BGE's common stock is listed on the New York, Chicago and Pacific Stock
Exchanges. The high and low sales prices of the common stock on February 18,
1999 were $27 1/8 and $26 3/16, respectively.

<PAGE>

                             REGULATORY APPROVALS

     MARYLAND PUBLIC SERVICE COMMISSION (MARYLAND PSC). The share exchange does
not require the approval of the Maryland PSC pursuant to Section 6-101(c) of
The Public Utility Companies Article of the Maryland Annotated Code.

     FEDERAL ENERGY REGULATORY COMMISSION (FERC). The FERC has said that the
transfer of a public utility's common stock from its existing shareholders to a
holding company constitutes a transfer of the ownership and control of the
utility's jurisdictional facilities and is thus a "disposition of facilities"
subject to FERC review and approval under Section 203 of the Federal Power Act.
In February, 1999, the FERC issued an order authorizing BGE to adopt the
proposed holding company structure.

     PENNSYLVANIA PUBLIC UTILITY COMMISSION (PA PUC). The Pa PUC has taken the
position that it must approve the proposed share exchange. BGE is subject to Pa
PUC regulation due to its partial ownership of Safe Harbor Water Power
Corporation, a hydroelectric plant, and two mine mouth generating plants
located in Pennsylvania. In February, 1999, BGE received the Pa PUC approval
for the share exchange.

     NUCLEAR REGULATORY COMMISSION (NRC). A provision in the Atomic Energy Act
requires that the NRC consent to the transfer of control of NRC licenses. The
staff of the NRC has in the past asserted that this provision applies to the
creation of a holding company by an NRC-licensed utility company in a
transaction such as the share exchange. BGE holds licenses, including an
operating license, for its Calvert Cliffs nuclear power plant. In November
1998, BGE applied for NRC approval of the share exchange, which is expected by
April 1, 1999. We do not anticipate any problems with obtaining this approval.


                       CONDITIONS TO THE SHARE EXCHANGE

     In addition to approval of the share exchange by BGE's common
shareholders, the share exchange is subject to the listing of Constellation
Energy's common stock with the New York Stock Exchange and receipt of NRC
approval without any unacceptable conditions attached to it.


                           AMENDMENT OR TERMINATION

     BGE's and Constellation Energy's Boards of Directors may amend or
terminate the Agreement and Plan of Share Exchange, or abandon the share
exchange at any time before it is completed. Following the approval of the
share exchange by BGE's common shareholders, no amendment to the Agreement and
Plan of Share Exchange may be made if it would materially and adversely affect
the rights of BGE shareholders, as determined in the sole judgment of BGE's
Board of Directors.


                      IMPLEMENTATION OF THE SHARE EXCHANGE

     The share exchange will be implemented pursuant to the Agreement and Plan
of Share Exchange (Appendix A) as follows:

   o each share of BGE common stock outstanding immediately prior to the share
     exchange will be automatically exchanged for one share of Constellation
     Energy common stock,

   o Constellation Energy will become the owner of all outstanding BGE common
     stock,

   o the shares of Constellation Energy common stock held by BGE immediately
     prior to the share exchange will be canceled, and


                                        
                                       16
 
REGULATORY APPROVALS
<PAGE>

     o the shares of the subsidiaries held by BGE will be distributed to
Constellation Energy.

     The Agreement and Plan of Share Exchange has been unanimously adopted by
BGE's Board of Directors and Constellation Energy's Board of Directors. The
terms of the Agreement and Plan of Share Exchange are incorporated into this
document as if the entire agreement was set forth here.

     Each person who owns BGE common stock immediately prior to the share
exchange will own the same number of shares of Constellation Energy common
stock immediately following the share exchange.


                   EXCHANGE OF BGE COMMON STOCK CERTIFICATES

     BGE common shareholders will not have to physically exchange their
existing stock certificates for certificates of Constellation Energy common
stock. The certificates which represent shares of BGE common stock outstanding
immediately before the share exchange will automatically represent an equal
number of shares of Constellation Energy common stock immediately after the
share exchange and will no longer represent BGE common stock. Thereafter, new
certificates in the name of Constellation Energy will be issued as old BGE
common stock certificates are presented for exchange or transfer.


                  LISTING OF CONSTELLATION ENERGY COMMON STOCK

     Constellation Energy has applied to have its common stock listed on the
New York, Chicago and Pacific Stock Exchanges to trade under the symbol "CEG."
We expect the listings to be effective when the share exchange is completed.
Quotations will be carried in major newspapers and other media as they have
been for BGE common stock. Following the share exchange, BGE common stock,
which will then be owned by Constellation Energy, will no longer trade on any
stock exchange and will be delisted.


           EXEMPTION FROM PUBLIC UTILITY HOLDING COMPANY ACT OF 1935

     Constellation Energy will be a "public utility holding company" under the
Public Utility Holding Company Act of 1935. However, Constellation Energy
expects to obtain an exemption under this law on the basis that it and BGE are
each organized and carry on their businesses substantially in Maryland and that
neither will derive any material part of their income from a public utility
company organized outside of Maryland. Constellation Energy will file for this
exemption the day the share exchange is effective. If obtained, Constellation
Energy would be exempt from all provisions of the law except the provision
requiring Securities and Exchange Commission approval for a direct or indirect
acquisition of 5 percent or more of the voting securities of any other electric
or gas utility company.

     To maintain the exemption, Constellation Energy must file an exemption
statement each year on or before March 1 with the Securities and Exchange
Commission. The exemption may be revoked by the Securities and Exchange
Commission if a substantial question of law or fact exists as to whether
Constellation Energy continues to meet the exemption's requirements, or if it
appears that the exemption may be detrimental to the public interest or the
interest of investors or consumers.

     If Constellation Energy is not exempt from this law, then it will be
subject to the law's provisions which would require Securities and Exchange
Commission approval for a wide range of transactions, including financings,
acquisitions, and intrasystem transactions. Constellation Energy would also be
subject to various accounting and reporting requirements.

                                       EXCHANGE OF BGE COMMON STOCK CERTIFICATES
<PAGE>

                            PREFERENCE STOCK OF BGE

     Approval of the share exchange will not alter the rights of BGE's
preference shareholders as provided in BGE's charter since the preference stock
is not being exchanged. BGE preference stock will continue to rank senior to
BGE's common stock held by Constellation Energy as to dividends and
distribution of BGE's assets upon any liquidation.

     Approval of the share exchange is not expected to affect adversely BGE's
preference shareholders and dividends are expected to continue to be paid as
before. However, if the share exchange is approved, the assets and earnings of
Constellation Energy's subsidiaries other than BGE will not be available to pay
dividends on BGE preference stock or to make distributions if there was a
liquidation of BGE.

     No fair value rights under Maryland law are available to the holders of
BGE's preference stock because the preference stock is not being exchanged.

     Following the share exchange, BGE will continue to be subject to the
informational requirements of the Securities Exchange Act of 1934, and will
continue to hold annual shareholder meetings.

     However, BGE does not intend to solicit proxies for these annual meetings
from preference shareholders (or preferred shareholders, if any) if the matters
to be voted at the meeting do not require the vote of those shareholders
pursuant to BGE's charter or Maryland law.


                   OBTAINING FAIR VALUE FOR BGE COMMON STOCK

     Pursuant to the Maryland General Corporation Law, holders of BGE common
stock who object to the share exchange may not demand fair value for their
stock. They are bound by the terms of the Agreement and Plan of Share Exchange,
if it is approved, because BGE common stock was traded on the New York Stock

     The Board met 7 times for regularly scheduled meetings in 1998. Each of
the nominees attended 75% or more of the total number of meetings of the Board
and of any committees on which they served.

     We do not pay directors who are also employees of BGE or its subsidiaries
for their service as directors. In 1998, compensation for non-employee
directors included the following:

      o $1,250 fee for each regular, committee or special Board meeting
        attended

        o directors may defer receipt of some or all of their fees

      o $26,000 annual retainer, and a $3,500 annual retainer for chairing
        committees

        o half of these retainers are invested in deferred stock units
          (explained below), and directors may elect to invest some or all of
          the other half of their retainers in deferred stock units

      o reasonable travel expenses to attend the meetings

     Deferred stock units are bookkeeping entries that track the performance of
BGE common stock and are not actual shares of stock. The bookkeeping entries
reflect BGE common stock price changes, dividends, stock splits and other
capital changes. At the end of their Board service, directors receive cash
based on the value of their deferred stock units.

  During the performance period, dividends on performance-based restricted
  stock are accumulated and used to purchase additional shares that are
  reflected in the above share numbers and market values. The market value
  for the shares held is based on the closing price per share for BGE common
  stock as listed in THE WALL STREET JOURNAL. Additional performance-based
  restricted stock was granted early in 1999 as described in the LONG-TERM
  INCENTIVE PLAN TABLE section beginning on page 25.

2 For 1997 the amounts were paid in BGE common stock for performance during the
  1995 - 1997 period. For 1996 the amounts were paid in cash for performance
  during the 1994 - 1996 period.

3 For 1996, 1997 and 1998, the amounts in the ALL OTHER COMPENSATION column
  include BGE's matching contributions under its savings plans, and the
  interest on the cumulative corporate funds used to pay annual premiums on
  policies providing split-dollar life insurance benefits (calculated at the
  Internal Revenue Service's blended rate). For 1996 and 1998, the amounts
  also include a contribution by BGE to a trust securing the executives'
  supplemental pension benefits. For 1996, the amounts also include a one-time
  contribution by BGE to fund a trust that was established in 1996 to secure
  executives' deferred compensation plan benefits. A breakdown of the 1998
  amounts in the ALL OTHER COMPENSATION column is shown in the table at the
  top of page 25.

LONG-TERM INCENTIVE PLAN TABLE

     The Committee on Management, early in 1999, made grants of restricted BGE
common stock under the Long-Term Incentive Plan. Grants under this plan were
not made during 1999 to Mr. Ambler (because he retired on January 1, 1999). The
grants are subject to both performance and time contingencies.

     For each named executive, except for Mr. Shivery, performance will be
measured over a three year period by comparing BGE's total shareholder return
to the Dow Jones Electric Utilities Index. Both are shown in the performance
graph on page 28. A minimum award will be earned if the BGE cumulative total
shareholder return percentile rank is at the 50th percentile, progressing to
the maximum award if the return is at or above the 75th percentile. Restricted
shares granted were equal to the number of shares of BGE common stock that will
be earned if "target" performance (62.5th percentile) is achieved.

     For Mr. Shivery, performance will be measured based on both BGE's total
shareholder return (as described above), and also by comparing subsidiary
business value appreciation to targets established by the Committee on
Management. The business value appreciation formula is based on the cumulative
net income, book value, and derived market value of Constellation Power Source.
Restricted shares were granted equal to the number of shares of BGE common
stock that will be earned if "target" performance is achieved, and there is no
maximum award limit. However, no awards will be made unless the subsidiary
cumulative net income threshold is achieved for the performance measurement
period. The measurement period for Mr. Shivery's grant is three years.

     For all named executives, all or a portion of these restricted shares will
be forfeited if performance is below target at the end of the performance
period. Additional shares will be awarded if performance is above target at the
end of the performance period. However, the total shares awarded will not
exceed any maximum noted in the table at the top of page 26.

     During the performance period, dividends on restricted shares will be
accumulated and reinvested in additional shares. At the end of the performance
period, actual dividends awarded will be based upon performance and paid in BGE
common stock (except that the recipients may elect to have a portion of the
shares withheld to satisfy tax withholding requirements). Dividend equivalents
from the date of the grant will be paid in stock for any additional shares that
are awarded. Shares earned through reinvested dividends are not counted toward
any maximum award limit.

PENSION BENEFITS

     The table below shows annual pension benefits payable at normal retirement
to executives, including the individuals named in the SUMMARY COMPENSATION
TABLE on page 24. Normal retirement occurs at age 65 for Messrs. Poindexter and
Crooke, and at age 62 for all other executives. Pension benefits are computed
at 60% of total final average salary plus bonus for Messrs. Poindexter and
Crooke, without regard to years of service. Pension benefits are computed at
50% of total final average salary plus bonus for Messrs. Shivery and Denton.
When Mr. Denton attains 30 years service in 2000, and Mr. Shivery attains 30
years service in 2001, their pension benefits will be computed at 55%. Pension
benefits for Mr. Heintz are computed at 40%. However, he will not be eligible
for pension benefits until he attains age 60 in 2004.

     When Mr. Ambler retired January 1, 1999, he had not yet attained
retirement age. However, his pension benefits were computed at 60% of total
final average salary plus bonus in recognition of his service as President and
Chief Executive Officer of Constellation Holdings, Inc.

EXECUTIVE COMPENSATION
<PAGE>

     Salary used to compute pension benefits is salary earned during the
preceding year. Salary is calculated in the same manner as shown in the SUMMARY
COMPENSATION TABLE on page 24. The bonus amount used to compute pension
benefits is the average of the two highest annual bonus percentages earned
during the preceding five years, multiplied by the prior year's final annual
salary. Bonus used in the calculation is based on the amounts shown in the
SUMMARY COMPENSATION TABLE. There is no offset of pension benefits for social
security or other amounts. Compensation used to compute pension benefits for
the individuals named in the SUMMARY COMPENSATION TABLE as of December 31, 1998
is as follows:


<TABLE>
<S>                    <C>
  C. H. Poindexter      $884,898
  C. W. Shivery         $312,628
  E. A. Crooke          $612,143
  B. M. Ambler          $460,928
  R. E. Denton          $345,858
  F. O. Heintz          $260,667
</TABLE>

     BGE has a program to secure the supplemental pension benefits for each
executive officer, and a program to secure deferred compensation of each
executive officer, including those listed in the SUMMARY COMPENSATION TABLE.
These programs do not increase the amount of supplemental pension benefits or
deferred compensation. To provide security, accrued supplemental pension
benefits and deferred compensation are funded through a trust at the time they
are earned. An executive officer's accrued benefits in the supplemental pension
trust become vested when any of these events occur: retirement eligibility;
termination, demotion or loss of benefit eligibility without cause; a change of
control of BGE followed within two years by the executive's demotion,
termination or loss of benefit eligibility; or reduction of previously accrued
benefits. As a result of becoming vested, the executive would be entitled to a
payout of the vested amount from the supplemental pension trust at the later of
age 55 or employment termination. An executive's benefits under the deferred
compensation plan always are fully vested and are payable at employment
termination. Any payments to these trusts are included in the SUMMARY
COMPENSATION TABLE in the "All Other Compensation" column.


SEVERANCE AGREEMENTS

     BGE has severance agreements with Messrs. Poindexter, Shivery, Crooke,
Denton, Heintz and three other key employees. Mr. Ambler's severance agreement
terminated effective with his retirement on January 1, 1999. The severance
agreements provide benefits if (1) there is a change in control of BGE, and (2)
within two years of the change in control, the executive's employment is
terminated without cause, or the executive resigns for good reason.

     The severance agreements provide benefits equal to two times the sum of
(1) the executive's annual base salary and (2) the average of the executive's
two highest annual incentive awards paid in the last five years. These payments
are made in 24 equal monthly installments beginning on the first day of the
month after employment ceases.

     For an executive who is ineligible to retire, the agreements also provide
retirement, medical and dental benefits computed assuming the executive: (1) is
the greater of age 55 or the executive's actual age; (2) has the greater of 10
years of service or actual service plus 3; and (3) has satisfied the minimum
service eligibility requirements for these benefits, and further provide for
continued life insurance benefits.

     For an executive who is eligible to retire, the agreements also provide
retirement benefits computed assuming the executive has the greater of 10 years
of service or actual service, and without any penalty for early retirement, and
medical and dental benefits based on the same terms as any retiree who is at
least age


                                        
                                       27

<PAGE>

65 with 20 or more years of service. Further, for purposes of other benefit
plans, the executive will be treated as retiring at BGE's request.

     In connection with Mr. Ambler's early retirement, and in recognition of
his service as President and Chief Executive Officer of Constellation Holdings,
Inc., he received a severance package when he retired on January 1, 1999. His
severance benefits include a $509,503 lump sum severance payment equal to the
total of (1) annual base salary, (2) average of the two highest annual bonus
percentages earned during the preceding five years multiplied by the prior
year's final annual salary, (3) payment toward the cost of active employee
health coverage for 12 months, and (4) vacation accrual. He also receives a 60%
pension benefit as described on page 26, and retired executive life insurance,
home security, planning, and club membership benefits. His effective cost of
medical and dental benefits beginning January 1, 2000 will be the same as if he
were retired at age 60 with 20 years of service. Mr. Ambler received a 1998
short-term incentive payment (as shown in the Bonus column of the SUMMARY
COMPENSATION TABLE on page 24), and will be entitled to a prorata payout of any
earned performance-based restricted stock award for the 1997-1999 and 1998-2000
performance periods.

REPORT OF COMMITTEE ON MANAGEMENT ON EXECUTIVE COMPENSATION

COMMITTEE ON MANAGEMENT
     The Committee on Management is responsible for executive compensation
policies. We also approve all compensation plans and recommend to the Board of
Directors specific salary amounts and other compensation awards for individual
executives. All of our Committee members are outside directors.


PHILOSOPHY

     We design compensation policies to encourage executives to manage BGE and
its subsidiaries in the best long-term interests of shareholders and to allow
BGE to attract and retain executives best suited to lead BGE in a changing
industry. We have retained an outside executive compensation consultant since
1993. He provides information and advice on a regular basis. In addition,
internal compensation analysts (certified by the American Compensation
Association) use published survey data, outside consultants, and other
resources to make recommendations to us.

     Our Committee determined that the relevant labor market for BGE executives
is the utility industry. Utilities used for comparison in 1998 were electric
utilities and combination electric/gas utilities, analyzed using regression
analysis to account for BGE's size. We believe these utilities best represent
the portion of the executive labor market in which BGE competes. Most of these
utilities are included in the Dow Jones Electric Utilities Index shown on the
Performance Graph on page 28. For subsidiary executives, we also used labor
market data from various industries that are similar to their diversified
businesses.

     The elements of executive compensation are:

     o base salary,

     o short-term incentive awards, and

     o long-term incentive awards.

     The Committee's philosophy is that base salary should approximate the
median level of the relevant labor market. Base salary and short-term incentive
awards should approximate the median level of the relevant labor market for
average performance, and the 75th percentile for superior performance.
Long-term incentive awards for superior performance should bring total
compensation to approximately the 75th percentile of the labor market. As
described below, corporate and/or diversified business performance are among
the criteria we use in determining base salary, and are key components in
determining both short-term and long-term incentive awards.


ANNUAL CASH COMPENSATION

     BASE SALARY. We used survey data and the policies mentioned above to
determine base salary range increases for Mr. Poindexter and the other named
executives in 1998.

     We determined base salary increases during 1998 for Mr. Poindexter and the
other named executives taking into account 1997 corporate and/or diversified
business performance, each executive's position in the salary range, individual
performance, and the corporate response to changes in the industry and the
regulatory environment. We did not assign specific weights to the various
factors. Mr. Poindexter's base salary increase of 4.1% maintained his position
in the middle third of his salary range.

     SHORT-TERM INCENTIVES. Bonus payments to Mr. Poindexter and other named
executives represent the short-term incentive component of executive
compensation. The Committee based the 1998 short-term incentives for Messrs.
Poindexter, Crooke and Ambler on two factors: corporate financial performance
weighted at


                                        
                                       29

                                            MANAGEMENT ON EXECUTIVE COMPENSATION
<PAGE>

75%, and the executives' contribution to the completion of the business plan
weighted at 25%. The Committee based the 1998 short-term incentives for Messrs.
Denton and Heintz on two factors that were weighted equally: corporate
financial performance and the executives' business plan performance. In
evaluating the corporate financial performance factor, the Committee determined
that earnings from ongoing operations was a more appropriate measure than
reported earnings, which included a number of one-time charges. In determining
the bonus payments for these executives, we also took into account a subjective
assessment of business plan performance and recognized that significant
progress was made during the year to prepare the corporation for competition in
the deregulated energy business. For Mr. Shivery, his 1998 short-term incentive
was based on Constellation Power Source and Constellation Energy Source
financial performance weighted at 75%, and his business plan performance
weighted at 25%. Mr. Shivery's bonus payment was based on Constellation Power
Source's net income greater than target and a subjective assessment of his
business plan performance. The bonus payments are shown in the SUMMARY
COMPENSATION TABLE on page 24.


LONG-TERM INCENTIVES

     The BGE Long-Term Incentive Plan will be in effect until 2005. The Plan
allows various types of awards keyed to corporate performance, including
performance shares and restricted stock subject to performance-based
contingencies. Performance-based restricted stock generally with three-year
performance periods was granted under the Plan in 1996, 1997, 1998 and 1999 to
the named executives (except Mr. Ambler who retired on January 1, 1999 and
consequently did not receive a 1999 grant). The performance period for the 1996
grants ended in 1998 and the reason why there were no award payouts is
described below. The 1997 and 1998 grants are shown in footnote 1 to the
SUMMARY COMPENSATION TABLE. The 1999 grants are shown on the Long-Term
Incentive Plan table on page 26. The awards are subject to forfeiture if
performance criteria are not satisfied or if the executive's employment
terminates for certain reasons during the applicable performance period.

     The performance criteria for the 1999 grants for all named executives
include a corporate total shareholder return measure for the three-year
performance period compared to total shareholder return for the other companies
included in the Dow Jones Electric Utilities Index (one of the indices used in
the Performance Graph). For this criterion, the award payout can range from a
threshold award at the 50th percentile, progressing to a maximum payout if
percentile rank for total shareholder return equals or exceeds the 75th
percentile. For BGE executives, total shareholder return has been the only
performance criterion since the 1996 grants.

     For Mr. Shivery's 1996 grant, corporate total shareholder return was the
sole performance criterion. For his 1997, 1998 and 1999 grants, the Committee
determined that it was also appropriate to establish a Constellation Power
Source (CPS) performance criterion for a portion of each award, to more closely
tie his long-term incentive compensation to CPS performance. The CPS
performance criterion is a business value appreciation formula, utilizing CPS
cumulative net income, book value, and derived market value. A cumulative net
income threshold will be established for each performance measurement period.
Since the business value appreciation formula is intended to measure a
surrogate market value, no maximum award amount was established. The number of
shares granted at the beginning of each performance period equals the targeted
value of the long-term incentive award.

     For Mr. Ambler's 1996 grant, the performance criterion measures
improvement in Constellation Holdings' cumulative net income over the
three-year period. For his 1997 grant, the performance criteria measure
corporate total shareholder return and Constellation Holdings' average return
on equity over the three-year period. For his 1998 grant, the criteria include
both corporate total shareholder return, and a business value appreciation
formula for Constellation Power, Inc. (CPI), the largest Constellation
Holdings' subsidiary. The business value appreciation formula for CPI is
similar to the formula for CPS described above.

REPORT OF COMMITTEE ON
MANAGEMENT ON EXECUTIVE COMPENSATION
<PAGE>

     The named executives did not earn awards of BGE common stock under the BGE
Long-Term Incentive Plan, based on the 1996-1998 performance period. There were
no awards for Messrs. Poindexter, Shivery, Crooke, Denton and Heintz because
BGE total shareholder return during the three-year performance period was below
the 50th percentile. Mr. Ambler also did not receive an award because
Constellation Holdings' cumulative net income over the three-year performance
period was below the minimum performance level.


POLICY CONCERNING $1 MILLION DEDUCTION LIMITATION

     Section 162(m) of the Internal Revenue Code limits tax deductions for
executive compensation to $1 million. There are several exemptions to Section
162(m), including one for qualified performance-based compensation. To be
qualified, performance-based compensation must meet various requirements,
including shareholder approval. Our Committee has considered annually whether
it should adopt a policy regarding 162(m) and concluded it was not appropriate
to do so. One reason for the conclusion is that, assuming the current
compensation policies and philosophy remain in place, the limitations of
Section 162(m) have no current impact, and are expected to have only minimal
applicability in the near future. Our Committee also notes that while generally
we wish to maximize the deductibility of compensation, we believe the 162(m)
requirements are not fully consistent with sound executive compensation policy
and incentives to improve shareholder value. Therefore, our Committee may
approve incentive payments that do not qualify for deduction if the recipient's
compensation exceeds the $1 million limit.

                       PROPOSAL NO. 3 -- RATIFICATION OF
                         PRICEWATERHOUSECOOPERS LLP AS
                       INDEPENDENT ACCOUNTANTS FOR 1999

     PricewaterhouseCoopers LLP, Certified Public Accountants, is the successor
to Coopers & Lybrand. It was formed when Price Waterhouse merged with Coopers &
Lybrand in 1998. Coopers & Lybrand has been BGE's independent accountants since
1941. A member of PricewaterhouseCoopers LLP will be at the annual meeting and
will have the opportunity to make a statement and answer appropriate questions.
 

     PricewaterhouseCoopers LLP audited BGE's 1998 consolidated financial
statements, as well as the financial statements of our Shareholder Investment
Plan and various employee benefit plans, and BGE's transfer agent functions. As
part of its audit function, they also reviewed BGE's 1998 annual report to
shareholders and various filings with the Securities and Exchange Commission
and Federal Energy Regulatory Commission. THE BOARD OF DIRECTORS RECOMMENDS A
VOTE "FOR" THIS PROPOSAL.


                        PROPOSAL NO. 4 -- A SHAREHOLDER
                          PROPOSAL CONCERNING CALVERT
                          CLIFFS' LICENSE EXTENSIONS

     We have been advised by the Maryland Safe Energy Coalition, c/o Richard
Ochs, 1443 Gorsuch, Baltimore, MD 21218, together with co-filers Virginia
Bates, 14949 Old Frederick Rd., Woodbine, MD 21797 and Anne Broderick, 9217
Waycross Rd., Ellicott City, MD 21042, shareholders who together each own
common stock with a market value of at least $2,000, that the following
proposal will be presented for action at the annual meeting.

     The Board of Directors' objection follows the shareholder proposal.

     The following proposal is presented word-for-word:

     A Shareholder Proposal to the Baltimore Gas and Electric Co. for its 1999
Annual Meeting


                    OPPOSE CALVERT CLIFFS LICENSE EXTENSION

     Whereas: Baltimore Gas and Electric Company has applied for a 20 year
     extension of the 40 year operating license for Calvert Cliffs Nuclear
     Plant;

     Whereas: The Calvert Cliffs Nuclear Plant was built and designed to
     operate for only 40 years;

     Whereas: Degradation and embrittlement of critical components threatens
     serious accidents which will cost the company, stockholders, Chesapeake
     Bay and nearby population;

     Whereas: Operating costs of the Calvert Cliffs plant are higher than other
     power sources and operating costs will continue to increase with age of
     the plant making the plant even more uneconomical;

     THEREFORE BE IT RESOLVED that the shareholders require the Board of
     Directors to close and decommission the Calvert Cliffs Nuclear Plant
     before or on the originally planned date.


                             SUPPORTING STATEMENT

     As this nuclear plant gets older, repairs will become more expensive, more
     numerous and more dangerous. Some of the components of the plant are
     inaccessible within reasonable cost. The estimate for replacement of the
     steam generators is $300 million! These costs will make it difficult for
     BG&E to


                                        
                                       32

RATIFICATION OF PRICEWATERHOUSECOOPERS LLP
AS INDEPENDENT ACCOUNTANTS FOR 1999
<PAGE>

     compete in a deregulated electric environment. Operation of the plant past
     its initial planned lifetime is therefore a bad plan for the company from
     a financial standpoint.

     Many of the larger nuclear plant parts can not be repaired or replaced at
     all. These pieces are becoming brittle due to neutron radiation from the
     reactor core. An emergency shutdown, rapid cooling and/or water hammer
     could cause these pieces to crack, fail and cause hugely expensive
     accidents. Emergency shutdowns occur on average twice a year in American
     nuclear power plants. Even 40 years is risky because the effects of
     neutron embrittlement were mostly unknown when the plant was built. In
     fact, no nuclear reactor has ever operated longer than 34 years, yet BG&E
     wants to try to operate the Calvert Cliffs reactors for 60 years. This is
     something no one anywhere has ever tried. Risky!

     The financial benefits from an additional 20 years of operation will be
     small due to the high operating costs which are sure to continue to
     increase. Meanwhile the risk of an accident will be going up as the plant
     passes its planned design lifetime. Any accident could destroy the
     Chesapeake Bay and contaminate Washington D.C. Our position is, "The
     benefits are too small to justify the greatly increased risk."



BOARD OF DIRECTORS' OBJECTIONS TO THE PROPOSAL ON CALVERT CLIFFS

     Our policy is to operate Calvert Cliffs Nuclear Power Plant in a safe and
efficient manner. The Plant, a key component of our generation strategy for the
future, provides customers our lowest cost energy in a safe and environmentally
sound manner. Calvert Cliffs is one of the primary reasons why our electric
service rates are among the lowest along the east coast.

     Ten years ago we began to study the long-term outlook for Calvert Cliffs,
in light of the expiration of the original operating license for Unit 1 in 2014
and Unit 2 in 2016. These studies included a component-by-component,
step-by-step analysis of the viability of extending the operating licenses and
financial and competitive evaluations. We also conducted a thorough assessment
of the Plant's condition, the need for future maintenance, and evaluated the
effect of embrittlement. We received Nuclear Regulatory Commission (NRC)
certification that the Plant will not experience the embrittlement alleged by
the proponents of the proposal during the remainder of the existing licenses or
during the 20-year renewed licenses.

     In fact, through an extensive, NRC-approved monitoring program, we
continuously manage the life cycle of the Plant to maintain optimum, safe
operation. Over the years, we have replaced and refurbished components and
structures to keep the Plant running safely and reliably. A significant example
of our life cycle management is the installation of the four new steam
generators at the Plant, expected to be installed in Unit 1 during the 2002
refueling outage and in Unit 2 during the 2003 refueling outage. We believe
that the new steam generators will pay for themselves before the current
license periods expire in 2014 and 2016, and will support operation of the
Plant throughout the license renewal periods.

     In recent years, by managing operating costs, Calvert Cliffs has produced
BGE's least expensive power. Calvert Cliffs is in the lower third of regional
nuclear plant costs. As a result, since 1993, we have been able to reduce the
fuel rate we charge customers 11 times. It is now at a 17 year low.

     Our overall goal is to make sure BGE maintains a competitive posture in
the marketplace. Obtaining a license renewal for both units at Calvert Cliffs
is a key part of that goal.


THE BOARD OF DIRECTORS RECOMMENDS A VOTE "AGAINST" THIS PROPOSAL. PROXIES
SOLICITED BY THE BOARD WILL BE SO VOTED UNLESS SHAREHOLDERS SPECIFY A CONTRARY
CHOICE ON THE PROXY CARD.

                              CONFIDENTIAL VOTING

     We have been advised by The Trust for the International Brotherhood of
Electrical Workers' Pension Benefit Fund, 1125 Fifteenth St. N.W., Washington,
D.C. 20005, owners of common stock with a market value of at least $2,000, that
the following proposal will be presented for action at the annual meeting.

     The Board of Directors' objection follows the shareholder proposal.

   The following proposal is presented word-for-word:


                    BALTIMORE GAS & ELECTRIC COMPANY (BGE)
                        SHAREHOLDER PROPOSAL CONCERNING
                              CONFIDENTIAL VOTING

       BE IT RESOLVED: That the stockholders of Baltimore Gas & Electric
   Company (BGE) ("Company"), recommend that our Board of Directors take the
   steps necessary to adopt and implement a policy of CONFIDENTIAL VOTING at
   all meetings of its stockholders, which includes the following provisions:

       1. That the voting of all proxies, consents and authorizations be
         secret, and that no such document shall be available for examination
         nor shall the vote or identity of any shareholder be disclosed except
         to the extent necessary to meet the legal requirements, if any, of the
         Corporation's state of incorporation; and

       2. That the receipt, certification and tabulation of such votes shall be
         performed by independent election inspectors.


                             SUPPORTING STATEMENT:

       It is the proponents' belief that it is vitally important that a system
   of CONFIDENTIAL PROXY VOTING be established at BGE. Confidential balloting
   is a basic tenet of our political electoral process ensuring its integrity.
   The integrity of corporate board elections should also be protected against
   potential abuses given the importance of corporate policies and practices
   to corporate owners (stockholders) and our national economy.

       The implementation of a CONFIDENTIAL VOTING SYSTEM would enhance
   shareholder rights in several ways. First, in protecting the
   confidentiality of the corporate ballot, shareholders would feel free to
   oppose management nominees and issue positions without fear of retribution.
   This is especially important for professional money managers whose business
   relationships can be jeopardized by their voting positions.

       A second important benefit of CONFIDENTIAL VOTING would be to invigorate
   the corporate governance process at the Corporation. We believe that
   shareholder activism would be promoted within the Corporation. It is our
   belief that shareholders empowered with a free and protected vote would be
   more active in the proposing of corporate policy resolutions and alternate
   board candidates.

       Finally, it is our belief that the enhancement of the proxy voting
   process would change the system where too often shareholders vote "with
   their feet," not with their ballots. This change would help to develop a
   long-term investment perspective where corporate assets could be deployed,
   and used in a more effective and efficient manner.

SHAREHOLDER PROPOSAL CONCERNING
CONFIDENTIAL VOTING

<PAGE>

   THE VAST MAJORITY OF MAJOR CORPORATIONS HAVE ADOPTED A CONFIDENTIAL VOTING
   POLICY AND IT'S TIME FOR BGE TO JOIN THEM.

                     WE URGE YOU TO VOTE FOR THIS PROPOSAL.


BOARD OF DIRECTORS' OBJECTIONS TO THE PROPOSAL ON CONFIDENTIAL VOTING

     A confidential voting policy would substantially limit the ability of
shareholders and BGE to communicate with each other, and would not
significantly enhance the confidentiality already available to shareholders.

     BGE's existing proxy solicitation system allows shareholders the freedom
to choose whether to vote on a confidential basis. A shareholder who wants
anonymity and confidentiality may hold shares in street name through a bank,
broker, or other nominee who cannot disclose the names of the shareholder
without the shareholder's permission. Shares held by employees in BGE's
employee savings plan are held in trust and voted by the plan trustee. BGE has
no access to the voting instructions employees provide to the trustee. Under
the terms of a trust agreement, plan participants confidentially direct the
trustee how to vote.

     Shareholders who choose not to vote on a confidential basis may openly
communicate with management. Large institutional shareholders use their votes
on particular issues to send messages to management. Other shareholders use
proxy cards to write comments to management. The Board of Directors must be
able to use these extremely valuable sources of information to learn the
viewpoints of its shareholders.

     A confidential voting policy would impair BGE's ability to contact
shareholders on issues that are important to BGE's success. The Board of
Directors must be able to clarify directly with shareholders issues of
importance to BGE and shareholders, and when necessary to counter false
statements in proxy contests. BGE may need to contact shareholders who have not
voted their proxies to encourage them to vote on important issues. BGE also may
contact shareholders whose proxy cards are not correctly completed, so that
their shares will be voted as they intended. Contact with shareholders is
critical in these situations so that the Board of Directors can proceed in the
best interest of BGE and all of its shareholders, and a confidential voting
policy would limit the Board of Directors' ability to do this.

     The proponent argues that confidential voting is necessary to ensure the
integrity of Board elections and protect shareholders from retribution. This is
a farfetched notion for corporate governance and has no historical basis at
BGE. BGE is a good corporate citizen as many long-time shareholders know, and
has always conducted its shareholder solicitations in a fair and equitable
manner, without any threat of retribution. Further, contrary to the proponent's
claim that shareholder activism would be promoted with confidential voting, it
has not been the experience of BGE that its shareholders are reluctant to
communicate with management because of the absence of confidential voting.
Activist shareholders want management to know who they are and what they stand
for.

     BGE's existing proxy solicitation system encourages open communication
with shareholders. It permits confidentiality for those who desire it, but does
not mandate it for all shareholders. The existing system has served
shareholders fairly for many years, and has been a valuable tool to help the
Board of Directors and management successfully run BGE.

                        GENERAL QUESTIONS & ANSWERS ON
                               VOTING PROCEDURES

WHAT IS A QUORUM OF SHAREHOLDERS, AND HOW MANY VOTES DOES IT TAKE TO PASS EACH
MATTER?
     A quorum is the presence at the annual meeting in person or by proxy of
shareholders entitled to cast a majority of all the votes entitled to be cast.
Since there were 149,556,416 shares of common stock outstanding on February 18,
1999, 74,778,209 shares is a quorum. Broker non-votes, abstentions and
withhold-authority votes COUNT for purposes of determining a quorum. We must
have a quorum to conduct the meeting. If a quorum of shareholders is present at
the meeting, we need the affirmative vote of the holders of two-thirds of the
outstanding shares of BGE common stock to approve the share exchange, a
plurality of all the votes cast to elect each director, and a majority of all
the votes cast to pass each of the other matters. Broker non-votes, abstentions
and withhold-authority votes DO NOT COUNT as votes cast.


HOW DO I VOTE?

You must be present, or represented by proxy, at the annual meeting in order to
vote your shares. Since many of our shareholders are unable to attend the
meeting in person, we send proxy cards to all of our shareholders.


IF MY SHARES ARE HELD IN "STREET NAME" BY MY BROKER, WILL MY BROKER VOTE MY
SHARES FOR ME?

Your broker has discretion to vote only for the election of directors and
ratification of the independent accountants. Your broker cannot vote your
shares on the share exchange or the shareholder proposals without your
instructions. You should instruct your broker to vote your shares on these
matters, following the directions your broker provides.


WHAT IS A PROXY?

A proxy is a person you appoint to vote on your behalf. We solicit proxies so
that all common shares may be voted at the annual meeting. You must complete
and return the enclosed proxy card to have your shares voted by proxy by BGE
management.


BY COMPLETING AND RETURNING THE PROXY CARD, WHO AM I DESIGNATING AS MY PROXY?

You will be designating Jerome W. Geckle, George V. McGowan, and Christian H.
Poindexter as your proxies.


HOW WILL MY PROXY VOTE MY SHARES?

Your proxy will vote according to the instructions on your proxy card. If you
complete and return your proxy card but do not indicate your vote on the
matters, your proxy will vote "FOR" Items 1, 2 and 3 and "AGAINST" Items 4 and
5. Also, your proxy card will give your proxy authority to vote, using his best
judgment, on any other business that properly comes before the meeting.


WHO IS ENTITLED TO VOTE AT THE ANNUAL MEETING, AND HOW MANY VOTES DO THEY HAVE?
 

Common shareholders who own shares as of February 18, 1999 may vote at the
meeting. Each share has one vote. There were 149,556,416 shares of common stock
outstanding on that date.

GENERAL QUESTIONS & ANSWERS ON
VOTING PROCEDURES

<PAGE>

HOW DO I VOTE USING MY PROXY CARD?

There are three steps.

   1. Vote on each of the matters as follows:

       o ITEMS 1, 3, 4 AND 5. You check the box "FOR," or "AGAINST," or
         "ABSTAIN" (to cast no vote).

       o ITEM 2. The names of all the directors to be elected are listed on your
         proxy card. You have three options:

          o OPTION 1. To vote for all directors, you check the box marked
            "FOR."

          o OPTION 2. To vote for some of the directors and against the rest,
            you check the box marked "FOR" and then draw a line through the
            names of the directors that you want to vote against.

          o OPTION 3. To abstain from voting for all directors (that is, not
            vote for or against any of the directors), you check the box marked
            "WITHHOLD AUTHORITY."

   2. Sign and date your proxy card. IF YOU DO NOT SIGN AND DATE YOUR PROXY
      CARD, YOUR VOTES CANNOT BE COUNTED.

   3. Mail your proxy card in the pre-addressed, postage-paid envelope.

REMEMBER TO CHECK THE BOX ON YOUR PROXY CARD IF YOU PLAN TO ATTEND THE ANNUAL
MEETING.


HOW DO I REVOKE MY PROXY?

You may revoke your proxy at any time before your shares are voted at the
annual meeting by:

     o notifying our Corporate Secretary, David A. Brune, in writing at P.O. Box
       1475, Baltimore, MD 21203-1475, that you are revoking your proxy; or

     o completing and sending in another proxy card at a later date; or

     o attending the annual meeting and voting by ballot.


WHY MIGHT I RECEIVE MORE THAN ONE PROXY CARD? SHOULD I VOTE ON EACH PROXY CARD
I RECEIVE?

First, you may have various accounts with us that are registered differently,
perhaps in different names or different social security or federal tax
identification numbers. Second, you may also own shares indirectly through your
broker or our employee savings plan. Your broker or our plan trustee will send
you a proxy card for these shares. You should vote on each proxy card you
receive and mail it to the address shown on the proxy card.


CAN I VOTE BY PROXY EVEN IF I PLAN TO ATTEND THE ANNUAL MEETING?

Yes. If you vote by proxy, you do not need to fill out a ballot at the annual
meeting, unless you want to change your vote.


WHO IS SOLICITING MY PROXY, HOW IS IT BEING SOLICITED, AND WHO PAYS THE COST?

BGE, on behalf of the Board of Directors, through its directors, officers and
employees, is soliciting proxies primarily by mail. However, proxies may also
be solicited in person, by telephone or facsimile. Georgeson & Company, Inc., a
proxy solicitation firm, will be assisting us for a fee of approximately
$19,500 plus out-of-pocket expenses. BGE pays the cost of soliciting proxies.

                      AGREEMENT AND PLAN OF SHARE EXCHANGE
                                    BETWEEN
                       BALTIMORE GAS AND ELECTRIC COMPANY
                                      AND
                        CONSTELLATION ENERGY GROUP, INC.


                                   RECITALS
     Baltimore Gas and Electric Company ("BGE") is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Maryland and has authorized one hundred seventy-five million (175,000,000)
shares of Common Stock, no par value. The shares of Common Stock, which are the
only shares entitled to vote on the share exchange, are entitled to one (1)
vote per share on this plan of share exchange.

     Constellation Energy Group, Inc. ("Constellation Energy"), a wholly-owned
subsidiary corporation of BGE, is a corporation duly organized, validly
existing and in good standing under the laws of the State of Maryland and has
authorized two hundred fifty million (250,000,000) shares of Common Stock, no
par value.

     The Board of Directors of BGE has adopted resolutions approving this
Agreement and Plan of Share Exchange (the "Agreement") and declaring the Plan
of Share Exchange advisable in accordance with the Maryland General Corporation
Law ("MGCL") and directing that the Agreement be submitted to the common
shareholders of BGE for approval.


                                   ARTICLE I
     1.01 BGE and Constellation Energy shall effect a share exchange (the
"Exchange") in accordance with and subject to the terms of this Agreement,
subject to (1) the receipt of all necessary regulatory approvals which do not
contain, in the sole judgment of the Board of Directors of BGE, unacceptable
conditions; (2) receipt of shareholder approval as required by the MGCL and
BGE's charter; and (3) amendment of Section 6-101(c) of the Public Utility
Companies Article of the Annotated Code of Maryland allowing BGE to form a
holding company which does not contain, in the sole judgment of the Board of
Directors of BGE, unacceptable conditions; (4) the receipt of approval of the
listing, on official notice of issuance, of the Constellation Energy Common
Stock; (5) the receipt of an opinion of counsel covering certain United States
federal income tax matters; and (6) the effectiveness of a registration
statement under the Securities Act of 1933 relating to Constellation Energy
Common Stock to be issued or reserved for issuance in connection with the
Exchange.

     1.02 The Articles of Share Exchange (the "Articles"), complying in all
respects with the MGCL, shall be delivered to the Maryland Department of
Assessments and Taxation ("MDAT"). The Exchange shall become effective as
specified in the Articles filed with the MDAT (the "Effective Time").


                                   ARTICLE II
     2.01 At the Effective Time, each share of BGE's Common Stock valid and
outstanding immediately prior to the Effective Time will be exchanged for one
(1) share of Constellation Energy's Common Stock, which Constellation Energy
shares shall be validly issued, fully paid and nonassessable, and Constellation
Energy shall thereupon have acquired and be the holder of each share of BGE's
Common Stock exchanged in the Exchange.
                                        
                                      A-1
<PAGE>

     2.02 Each share of BGE's Common Stock held in the treasury of BGE
immediately prior to the Effective Time shall be cancelled and shall be
restored to the status of an authorized but unissued share of BGE's Common
Stock.

     2.03 Immediately after the Effective Time, all of the issued and
outstanding shares of BGE's Common Stock will be held by Constellation Energy,
and all of the issued and outstanding shares of Constellation Energy Common
Stock will be held by the holders of shares of BGE's Common Stock that were
outstanding immediately prior to the Effective Time.

     2.04 Shares of BGE's preferred and preference stock shall not be exchanged
or otherwise affected by this plan of share exchange. Each share of BGE's
preferred and preference stock issued and outstanding immediately prior to the
Effective Time of the share exchange shall continue to be issued and
outstanding following the Exchange.

     2.05 Each outstanding certificate which immediately prior to the Effective
Time represents BGE's Common Stock shall, without any further action on the
part of the holder thereof, be deemed and treated for all corporate purposes to
represent the ownership of the same number of shares of Constellation Energy
Common Stock as though a surrender or transfer and exchange had taken place.
The holders of BGE's Common Stock at the Effective Time shall have no right at
and after the Effective Time to have their shares of BGE's Common Stock
transferred on the stock transfer books of BGE (such stock transfer books being
deemed closed for this purpose at the Effective Time) and at and after the
Effective Time such stock transfer books may be deemed to be the stock transfer
books of Constellation Energy.

     2.06 At the Effective Time, Constellation Energy shall adopt a shareholder
investment plan ("Constellation Energy SIP") substantially similar to BGE's
Shareholder Investment Plan ("BGE SIP") in effect immediately prior to the
Effective Time and the BGE SIP shall be discontinued. At the Effective Time,
all shares of BGE's Common Stock held under the BGE SIP (including fractional
and uncertificated shares) shall be exchanged for shares (including fractional
and uncertificated shares) of Constellation Energy Common Stock and shall be
held pursuant to the Constellation Energy SIP. At the Effective Time,
Constellation Energy shall adopt, become subject to and/or agree to issue
Constellation Energy Common Stock in connection with BGE's Employee Savings
Plan, 1995 Long-Term Incentive Plan, and the Manager Long-Term Incentive Plan
(collectively, the "BGE Plans"); and, by virtue of the Exchange and without any
action on the part of the holder thereof, each right or option under the BGE
Plans to purchase shares of BGE's Common Stock granted and outstanding
immediately prior to the Effective Time shall be converted into and become a
right or option to purchase an equivalent number of shares of Constellation
Energy Common Stock at the same price per share, and upon the same terms and
subject to the same conditions, as applicable immediately prior to the
Effective Time under the relevant right or option.

     Constellation Energy will reserve, for purposes of the BGE Plans, a number
of shares of Constellation Energy Common Stock equivalent to the number of
shares of BGE's Common Stock reserved by BGE for such purposes immediately
prior to the Effective Time.

     2.07 Prior to or as of the Effective Time, BGE shall cause each director
of BGE who is not then also a director of Constellation Energy to be elected a
director of Constellation Energy, so that as of the Effective Time,
Constellation Energy will have 15 board members.

     2.08 Immediately prior to the Effective Time, each share of Constellation
Energy's Common Stock issued and outstanding immediately before the Effective
Time shall be cancelled and thereupon shall constitute an authorized but
unissued share, and all rights in respect thereof shall cease. BGE, pursuant to
the Agreement, as the sole holder of Constellation Energy's Common Stock,
consents to such cancellation.

                                  ARTICLE III
     3.01 Notwithstanding satisfaction of the conditions specified in Article I
of this Agreement, this Agreement may be amended or terminated or the Exchange
abandoned at any time prior to the Effective Time. Following adoption of the
Plan of Share Exchange by stockholders of BGE, no amendment to this Agreement
may materially and adversely affect the rights of the stockholders of BGE, as
determined in the sole judgment of the Board of Directors of BGE.

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement and
Plan of Share Exchange as of February 19, 1999.

       (i)  twenty-five million (25,000,000) shares are Preferred Stock, $.01
            par value per share, all of which are authorized but unissued and

            Corporation, in any manner whatsoever, shall be retired and
            cancelled promptly after the acquisition thereof. All such shares
            shall upon their cancellation become authorized but unissued shares
            of Preferred Stock, without designation as to series, and may be
            reissued as part of any series of Preferred Stock created by
            resolution or resolutions of the Board of Directors, subject to the
            conditions and restrictions on issuance set forth in these Articles
            of Incorporation or in such resolution or resolutions; and

     SEVENTH: POWERS OF THE CORPORATION. The following provisions are hereby
adopted for the purpose of defining, limiting and regulating the powers of the
Corporation and its Directors and stockholders:

   (a) The Board of Directors of the Corporation is hereby empowered to
       authorize the issuance from time to time of shares of its stock of any
       class, whether now or hereafter authorized, or securities convertible
       into shares of its stock of any class, whether now or hereafter
       authorized, without the approval of the stockholders of the Corporation
       for such consideration as is determined by the Board of Directors in
       accordance with applicable law.

   (b) Notwithstanding any other provision contained in these Articles of
       Incorporation, the Board of Directors of the Corporation may authorize
       the issuance of some or all of the shares of Common Stock or Preferred
       Stock of any or all classes or series authorized under these Articles of
       Incorporation without certificates. This authorization shall not affect
       shares already represented by certificates outstanding until they are
       surrendered to the Corporation.

   (c) No stockholder of the Corporation shall have preferential or preemptive
       rights to subscribe for, purchase or otherwise acquire any stock or
       other securities of the Corporation, now or hereafter authorized, and
       any and all preemptive rights are hereby denied.

   (d) The Corporation reserves the right from time to time to make any
       amendment of its Charter, now or hereafter authorized by law, including
       any amendment which alters the contract rights, as expressly set forth
       in the Charter, of any outstanding stock.

   (e) The Board of Directors may classify or reclassify any unissued shares
       of stock of the Corporation by setting or changing in any one or more
       respects, from time to time before issuance of such shares, the
       preferences, conversion and other rights, voting powers, restrictions,
       limitations as to dividends, qualifications or terms or conditions of
       redemption of such shares.

   (f) With respect to any corporate action to be taken by the Corporation
       which, under the Maryland General Corporation Law, would (in the absence
       of this subparagraph (f) of this Article SEVENTH) require the
       authorization or approval of a greater proportion than a majority of all
       votes entitled to be cast for such action to be effective and valid,
       such corporate action shall be effective and valid if authorized or
       approved by at least a majority of all the votes entitled to be cast
       thereon, after due authorization and/or approval and/or advice of such
       action by the Board of Directors as required by law.

   EIGHTH: INDEMNIFICATION AND LIMITATION OF LIABILITY.

   (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


                                        
                                      B-3
<PAGE>

            arrangements as may 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.

                                 STOCKHOLDERS

Section 1. -- PLACE OF MEETINGS.

     Meetings of stockholders of the Corporation shall be held at such places,
either within or without the State of Maryland as may be fixed from time to

Section 2. -- ANNUAL MEETINGS.

     The Annual Meeting of the stockholders for the election of Directors and
for the transaction of general business shall be held on any date during the
period of April 14 through May 13, as determined year to year by the Board. The
time and location of the meeting shall be determined by the Board. Failure to
hold an Annual Meeting does not invalidate the Corporation's existence or
affect any otherwise valid corporate acts.

     The Chief Executive Officer of the Corporation shall prepare, or cause to
be prepared, an annual report containing a full and correct statement of the
affairs of the Corporation, including a balance sheet and a financial statement
of operations for the preceding fiscal year, which shall be submitted to the
stockholders at or prior to the Annual Meeting.

Section 3. -- SPECIAL MEETINGS.

     Special meetings of the stockholders may be held in the City of Baltimore
or in any county in which the Corporation provides service or owns property
upon call by the Chairman of the Board, the President, or a majority of the
Board whenever they deem expedient, or by the Secretary upon the written
request of the holders of shares entitled to not less than twenty-five percent
of all the votes entitled to be cast at such meeting. Such request of the
stockholders shall state the purpose or purposes of the meeting and the matters
proposed to be acted on thereat and shall be delivered to the Secretary, who
shall inform such stockholders of the reasonably estimated cost of preparing
and mailing such notice of the meeting, and upon payment to the Corporation of
such costs the Secretary shall give notice stating the purpose or purposes of
the meeting to all


                                        
                                      C-1
<PAGE>

stockholders entitled to vote at such meeting. No special meeting need be
called upon the request of the holders of the shares entitled to cast less than
a majority of all votes entitled to be cast at such meeting, to consider any
matter which is substantially the same as a matter voted upon at any special
meeting of the stockholders held during the preceding twelve months. The
business at all special meetings shall be confined to that specifically named
in the notice thereof.

Section 4. -- NOTICE AND WAIVER; ORGANIZATION OF MEETING.

     When stockholders are required or permitted to take any action at a
meeting whether special or annual, written or printed notice of every meeting
shall be given to each stockholder entitled to vote at the meeting and each
other stockholder entitled to notice of the meeting. The notice shall state the
place, day, and hour of such meeting and, in the case of a special meeting, the
purpose or purposes for which the meeting is called. The written notice of any
meeting shall be given, personally or by mail, not less than 10 or more than 90
days before the date of the meeting. If mailed, such notice shall be deemed
given when deposited with the United States Postal Service, postage prepaid,
addressed to the stockholder at his or her address as it appears on the records
of the Corporation or its registrar. The business at all special meetings shall
be confined to that specifically named in the notice thereof.

     When a meeting is adjourned to another time or place, notice need not be
given of the adjourned meeting if the time and place thereof are announced at
the meeting at which the adjournment is taken unless the adjournment is for
more than 120 days, or, if after the adjournment, a new record date is fixed
for the adjourned meeting, in which circumstances a notice of the adjourned
meeting shall be given to each stockholder of record entitled to vote at the
meeting. At the adjourned meeting the Corporation may transact any business
which might have been transacted at the original meeting.

     Notice of any meeting of stockholders may be waived in writing by any
stockholders entitled to vote at such meeting. Attendance at a meeting by any
stockholder, in person or by proxy, shall constitute a waiver of notice of such
meeting, except when the person attends a meeting for the express purpose of
objecting, at the beginning of the meeting, to the transaction of any business
because the meeting is not lawfully called or convened.

     All meetings of the stockholders shall be called to order by the Chairman
of the Board, or in his or her absence by the President or a Vice President; or
in the case of the absence of such Officers, then by any stockholder. The party
calling the meeting to order shall be Chairman of the meeting. The Secretary of
the Corporation, if present, shall act as secretary of the meeting, unless some
other person shall be elected by the stockholders at the meeting to act as
secretary. An accurate record of the meeting shall be kept by the secretary
thereof, and placed in the record books of the Corporation.

Section 5. -- ORDER OF BUSINESS.

    (a) At any Annual Meeting, only such business shall be conducted as shall
        have been brought before the Annual Meeting (i) by or at the direction
        of the Board, or (ii) by any stockholder who complies with the
        procedures set forth in this Section 5.

    (b) For nominations or other business to be brought properly before an
        Annual Meeting by a stockholder, the stockholder must have given timely
        notice thereof in proper written form to the Secretary of the
        Corporation. To be timely, a stockholder's notice must be delivered to
        or mailed and received at the principal office of the Corporation not
        less than 75 days prior to the anniversary of the date on

<PAGE>

        which notice of the prior year's Annual Meeting was given to
        stockholders in accordance with Section 4 of this Article II. Notices by
        facsimile will not be accepted by the Secretary of the Corporation. To
        be in proper written form, a stockholder's notice to the Secretary shall
        set forth in writing as to each matter the stockholder proposes to bring
        before the Annual Meeting:

        (i) as to each person whom the stockholder proposes to nominate for
            election or re-election as a Director, all information relating to
            such person that is required to be disclosed in solicitations of
            proxies for election of Directors, or is otherwise required, in each
            case pursuant to Regulation 14A under the Securities Exchange Act of
            1934 (the "Exchange Act") or any applicable successor provisions
            thereto, including such person's written consent to being named in
            the proxy statement as a nominee and to serving as a Director if
            elected; and as to the stockholder giving the notice, the name and
            address, as they appear on the Corporation's books, of the
            stockholder proposing such nomination and the class and number of
            shares of stock of the Corporation which are beneficially owned by
            the stockholder.

        (ii) as to any other business that the stockholder proposes to bring
            before the meeting:

            (A) a brief description of the business desired to be brought before
                the Annual Meeting and the reasons for conducting such business
                at the Annual Meeting;

            (B) the name and address, as they appear on the Corporation's books,
                of the stockholder proposing such business;

            (C) the class and number of shares of stock of the Corporation which
                are beneficially owned by the stockholder; and

            (D) any material interest of the stockholder in such business.

    (c) Notwithstanding anything in these by-laws to the contrary, no business
        shall be conducted at an Annual Meeting except in accordance with the
        procedures set forth in this Section 5 of Article II. The Chairman of an
        Annual Meeting shall, if the facts warrant, determine and declare at the
        Annual Meeting that business was not properly brought before the Annual
        Meeting in accordance with the provisions of this Section 5 of Article
        II and, if the Chairman should so determine, he or she shall so declare
        at the Annual Meeting and any such business not properly brought before
        the Annual Meeting shall not be transacted.

    (d) Notwithstanding the foregoing provisions of this Section, a stockholder
        shall also comply with all applicable requirements of the Exchange Act
        and the rules and regulations thereunder with respect to the matters set
        forth in this Section. Nothing in this Section shall be deemed to affect
        any rights of stockholders to request inclusion of proposals in the
        Corporation's proxy statement pursuant to Rule 14a-8 under the Exchange
        Act.

Section 6. -- QUORUM.

     At any meeting of the stockholders the presence in person or by proxy of
stockholders entitled to cast a majority of the votes thereat shall constitute
a quorum for the transaction of business.

     When a quorum is once present to organize a meeting, it is not broken by
the subsequent withdrawal of any stockholders.

     The stockholders present, although less than a quorum, may adjourn the
meeting to another time or place; provided that notice of such adjourned
meeting is given in accordance with the provisions of Section 4 of this Article
II.

Section 7. -- VOTING; PROXIES.

     At all meetings of the stockholders each stockholder shall be entitled to
one vote for each share of Common Stock standing in his or her name and, when
the Preferred Stock is entitled to vote, such number of votes as shall be
provided in the Charter of the Corporation for each share of Preferred Stock
standing in his or her name, and the votes shall be cast by stockholders in
person or by lawful proxy. However, no proxy shall be voted 11 months after the
date thereof, unless the proxy provides for a longer period.

Section 8. -- METHOD OF VOTING.

     All elections and all other questions shall be decided by a majority of
the votes cast, at a meeting at which a quorum is present, except as expressly
provided otherwise by the general laws of the State of Maryland or the Charter
and except that Directors shall be elected by a plurality of the votes cast.

Section 9. -- OWNERSHIP OF ITS OWN STOCK.

     Shares of capital stock of the Corporation held by either (i) the
Corporation or (ii) another corporation, if a majority of the shares entitled
to vote in the election of Directors of such other corporation is held,
directly or indirectly, by the Corporation (a "Controlled Corporation"), shall
neither be entitled to vote nor be counted for quorum purposes. Nothing in this
Section 9 shall be construed as limiting the right of the Corporation or any
Controlled Corporation to vote stock of the Corporation held by it in a
fiduciary capacity.

Section 10. -- JUDGE OF ELECTION AND TELLERS.

     The Directors shall, at a regular or special meeting, appoint a Judge of
Election and two Tellers to serve at each meeting of stockholders. If the
Directors fail to make such appointments, or if the Judge of Election and/or
Tellers, or any of them, fail to appear at the meeting, the Chairman of the
meeting shall appoint a Judge of Election and/or a Teller or Tellers to serve
at that meeting. It shall be the duty of the Tellers to receive the ballots of
all the holders of stock entitled to vote and present at a meeting either in
person or by proxy, and to count and tally said ballots by the official record
of stockholders of the Corporation, or by a summary prepared therefrom and
certified by the Stock Transfer Agent or the Secretary of the Corporation
showing the number of shares of Common and, if entitled to vote, Preferred
Stock owned of record by each stockholder, who may be designated therein by
name, code number, or otherwise, and certify them to the Judge of Election, and
the said Judge shall communicate in writing the result of the balloting so
certified by the Tellers to the Chairman who shall at once announce the same to
the meeting. This certificate, signed by the Tellers and countersigned by the
Judge, shall be duly recorded as part of the minutes of the meeting and filed
among the records of the Corporation.

Section 11. --  RECORD DATE FOR STOCKHOLDERS; CLOSING OF TRANSFER BOOKS.

     The Board may fix, in advance, a date as the record for the determination
of the stockholders entitled to notice of, or to vote at, any meeting of
stockholders, or entitled to receive payment of any dividend, or entitled to
the allotment of any rights, or for any other proper purpose. Such date in any
case shall not be more than 90 days (and in the case of a meeting of
stockholders not less than 10 days) prior to the date on which the particular
action requiring such determination of stockholders is to be taken. Only
stockholders of record on such date shall be entitled to notice of or to vote
at such meeting or to receive such dividends or rights, as the case may be. In
lieu of fixing a record date the Board may close the stock transfer books of
the Corporation for a period not exceeding 20 nor less than 10 days preceding
the date of any meeting of stockholders or not exceeding 20 days preceding any
other of the above mentioned events.

Section 5. -- MEETINGS OF THE BOARD.

     A regular meeting of the Board shall be held immediately after the Annual

Chairman of the Board, or the President, or in their absence, on order of the
Executive Committee by notices as above. In the event three-fourths of the
Directors in office waive notice of any meeting in writing at or before the

Section 8. -- EXECUTIVE COMMITTEE.

     The Directors shall annually, at their first meeting succeeding the
stockholders' meeting at which they are elected, elect from among their number
an Executive Committee of at least three. The Executive Committee may exercise,
in the intervals between meetings of the Board, all of the powers of the Board
in the management of the business and affairs of the Corporation, except the
power to declare dividends, to issue stock other than as hereinafter stated, to
recommend to stockholders any action requiring stockholder approval, amend the
by-laws, or approve any merger or share exchange which does not require
stockholder approval. If the Board has given general authorization for the
issuance of stock, the Executive Committee, in accordance with a general
formula or method specified by the Board by resolution or by adoption of a
stock option or other plan, may fix the terms of stock subject to
classification or reclassification and the terms on which any stock may be
issued, including all terms and conditions required or permitted to be
established or authorized by the Board.

     The members of the Executive Committee shall hold their offices as such
for one year and until their successors are elected and qualified, or until
their earlier resignation or removal. All vacancies in said Committee shall be
filled by the Board, but in the absence of a member or members of the Executive
Committee, the members thereof present at any meeting (whether or not they
constitute a quorum) may appoint a member of the Board to act in the place of
such absent member. They shall designate one of their number as Chairman of the
Committee, and shall keep a separate book of minutes of their proceedings and
actions. They shall elect a Secretary to the Committee who shall give notice
personally or by mail, telephone, or facsimile to each member of the Committee
of all meetings, not later than 12 noon of the day before the meeting, unless a
majority of the members of the Executive Committee in office waive notice
thereof in writing at or before the meeting in which case the meeting may be
held without the aforesaid advance notice. Meetings may be called by the
Chairman of the Committee or by the Chief Executive Officer, or, in the event
of their absence, by one of the other Officers among the Chairman of the Board,
the President or the Vice Presidents (if a member of the Board). A majority of
the members of the Executive Committee shall constitute a quorum for the
transaction of business.

     The Directors shall annually, at their first meeting succeeding the
stockholders' meeting at which they are elected, elect from among their number
an Audit Committee which shall consist of at least three Directors who shall be
independent of Management and free from any relationship that, in the opinion
of the Board, would interfere with the exercise of independent judgment as a
Committee member, PROVIDED that no Director

                                      C-6
<PAGE>

who was formerly an Officer of the Corporation shall be a member of the said
Audit Committee. The members of the Audit Committee shall hold their offices as

shall be filled by the Board. They shall designate one of their number as
Chairman of the Committee, and shall keep a separate book of minutes of their
proceedings and actions. They shall elect a Secretary to the Committee who

                     INFORMATION NOT REQUIRED IN PROSPECTUS

               ITEM 20. 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 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 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

                                      II-1
<PAGE>

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

                                      II-2

<PAGE>

such by-laws, resolutions or contracts implementing such provisions or such
further indemnification arrangements as may be permitted by law. No amendment of
the Charter of the Corporation 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

                                      II-3


<PAGE>

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.

         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 Commission by Registrant pursuant to Section
         13 or Section 15(d) of the Securities Exchange Act of 1934 that are
         incorporated by reference in the registration statement.

         (2) That, for the purpose of determining any liability under the
             Securities Act of 1933, each such post-effective amendment shall be
             deemed to be a new registration statement relating to the
             securities offered therein, and the offering of such securities at

                                      II-6
<PAGE>

             that time shall be deemed to be the initial bona fide offering
             thereof; and

         (3) to remove from registration by means of a post-effective amendment
             any shares of Constellation Energy common stock which are not
             issued in the share exchange.

(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 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 foregoing provisions, 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.

(d) The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11, or 13 of this Form S-4, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.

post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and

Gentlemen:

     This opinion is provided in connection with Post Effective Amendment No. 1
to Registration No. 33-64799 on Form S-4 (the "Registration Statement ("CEG")
filed by Constellation Energy Group, Inc. (formerly Constellation Energy
Corporation) with the Securities and Exchange Commission ("Commission") under
the Securities Act of 1933, regarding the proposed issuance of up to 154 million
shares of Constellation Energy common stock, no par value (the "Common Shares").
The Common Shares will be issued in connection with the proposed share exchange
between CEG and the common stockholders of Baltimore Gas and Electric Company
("BGE") as described in the Agreement and Plan of Share Exchange dated as of
February 19, 1999 between BGE and CEG, (the "Agreement"). The Agreement is filed
as Appendix A to the Registration Statement.

     I am Deputy General Counsel of BGE, a Maryland corporation, and head of its
Legal Department. BGE is the sole shareholder of CEG, and CEG has requested that
I provide this opinion. I am licensed to practice law in the State of Maryland.
In connection with this opinion, I, together with attorneys I supervise, have
considered, among other things (1) the proposed Amended and Restated Articles of
Incorporation of CEG filed as Appendix B to the Registration Statement (the
"Proposed Charter"); (2) the proposed by-laws of CEG filed as Appendix C to the


<PAGE>

Constellation Energy Group, Inc.

Registration Statement (the "Proposed By-laws"); (3) the corporate proceedings
for approval of the issuance and sale of the Common Shares; (4) the Registration
Statement; (5) the Agreement; (6) the provisions of the Public Utility Holding
Company Act of 1935 (the "1935 Act"), together with an order dated January 16,
1956 issued by the Commission (File No. 31-631) exempting BGE from the
provisions of the 1935 Act applicable to it as a holding company; and (7) such
other documents, transactions, and matters of law as we deemed necessary or
desirable in order to render this opinion.

     This opinion is subject to (1) appropriate resolutions being adopted by the
CEG Board of Directors prior to the issuance of the Common Shares; (2) the
Registration Statement becoming effective under the Securities Act of 1933; (3)
proper adoption, filing, and recording of the Proposed Charter and the proper
adoption of the Proposed By-laws so that both are in effect at the time of
issuance of the Common Shares; and (4) the proposed share exchange being
consummated as contemplated in the Agreement.

     Based on the foregoing, I am of the opinion that the Common Shares, when
issued and delivered in accordance with the provisions of the Agreement, will
constitute legally issued, fully paid and nonassessable shares of CEG common
stock.

     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 and to the references to me in the Registration Statement

Attn:  David A. Brune, Vice-President

Dear Mr. Brune:

           Baltimore Gas and Electric Company ("BGE") has asked for our opinion
regarding certain federal income tax consequences of a proposed share exchange
in which Constellation Energy Group, Inc. ("Constellation Energy") will acquire
all of the common stock of BGE. As explained in more detail below, we believe
that the proposed share exchange will qualify as a tax-free transaction under
the federal income tax laws, so that the participants in the exchange will not
recognize any income, gain or loss as a result of the exchange. A more specific
statement of our conclusions follows summaries of the relevant facts and the
analysis that supports our conclusions. Our conclusions are based on our review
of (i) drafts of relevant documents, including the proxy statement for BGE's
1999 annual meeting of shareholders, the Agreement and Plan of Share Exchange
between BGE and Constellation Energy, the Amended and Restated Articles of
Incorporation of Constellation Energy, and the amended By-Laws of Constellation
Energy, (ii) the representations provided in the letter to us dated this date
from David A. Brune, Vice President, Chief Financial Officer, and Secretary of
BGE, and (iii) other information that BGE has provided to us.

                                      FACTS

           THE PARTIES. BGE is engaged in the utility business. Its activities
include the generation, purchase and sale of electricity and the purchase,
transportation and sale of natural

gas. BGE has six classes of stock outstanding: common stock and five classes of
preference shares. The common shares are widely-held and are traded on the New
York Stock Exchange. The preference shares, although issued in public offerings,
are not traded on any exchange.

           The preference shares generally provide their holders with limited
but preferred rights. Holders of preference shares are entitled to vote in only
two circumstances. First, a favorable vote of the holders of two-thirds of the
preference shares is required for any amendment of BGE's charter that would
create or authorize any stock that would rank prior to or on a parity with the
preference shares as to dividends or distribution of assets or that would
substantially adversely affect the rights of the preference shares. Second, if
BGE were to fail to pay full dividends on a class of preference shares for one
year, the holders of those shares would be entitled to one vote per share on all
matters until BGE pays in full the deficiency in dividends. No such deficiency
in dividends on BGE preference shares currently exists. The holders of each
class of preference stock are entitled to dividends, as and when declared, equal
to a fixed rate that varies by class. Dividends on each class of preference
shares are cumulative, and must be paid before any dividends may be paid on
common stock. Each class of preference shares is redeemable at the option of the
Board of Directors by payment of a prescribed redemption price plus accrued
dividends. The prescribed redemption price includes a premium over par ($100)
that declines with time. The 7.78% Cumulative Preference Stock, 1973 Series may
be redeemed at any time. The redemption price for these shares began at $108 per
share for any redemptions prior to December 1, 1978 and has declined to $101 per
share for any redemptions after December 1, 1988. The shares in the remaining
series, issued in 1993 and 1995, are not currently redeemable, but become
redeemable ten years after issuance. In each case, the maximum premium, for
redemptions that occur ten years after issuance, would be less than $4. The
stated premium then declines each year, and is eliminated entirely for
redemptions that occur twenty or more years after issuance. Upon the
liquidation, dissolution, or winding up of BGE, the holders of the preference
shares will be entitled to receive, from any assets of BGE remaining after
payment of debts and claims, the par value of their shares plus any accrued
dividends on those shares. All of the preference shares were issued at their par
value of $100. The preference shares are not convertible into shares of another
class of BGE stock.

           Constellation Energy is a wholly-owned subsidiary of BGE. It was
formed in 1995 for the purpose of a proposed transaction that did not occur.
Since its formation, Constellation Energy has not held any assets or engaged in
any business operations.

           Constellation Enterprises, Inc. ("Constellation Enterprises") is also
a wholly-owned subsidiary of BGE. Constellation Enterprises owns the stock of
several other companies primarily engaged in unregulated, energy-related
businesses.

           THE TRANSACTION. Management of BGE has determined that it would be
advisable to establish a holding company to own the stock of BGE and
Constellation Enterprises. This structure will divide between separate chains of
corporations BGE's regulated business and the unregulated businesses conducted
by Constellation Enterprises and its subsidiaries. This separation of regulated
and unregulated businesses will have several favorable effects. First, the new
structure will allow funds to be raised for the unregulated businesses more
efficiently. Second, the structure will facilitate valuation of the separate
lines of businesses by the investment community. Third, it will allow regulators
to more easily verify the absence of any subsidies between the two types of
businesses. Fourth, it will protect the assets of the regulated business from
claims arising from the unregulated businesses.

           To carry out the purposes described above, BGE management has
proposed that Constellation Energy be established as a holding company that will
own all of the stock of Constellation Enterprises and all of the common stock of
BGE. The establishment of Constellation Energy as a holding company will be
accomplished by means of a statutory "share exchange" under section 3-102(a)(7)
of the Maryland Corporations and Associations Code. The Boards of Directors of
both BGE and Constellation Energy have each unanimously adopted a draft
Agreement and Plan of Share Exchange (the "Draft Agreement"). As a result of the
share exchange, the holders of BGE common stock will be deemed to have exchanged
their BGE stock for Constellation Energy common stock, as provided in articles
of share exchange that will be filed with the Maryland Department of Assessments
and Taxation. MD. CODE ANN., CORPS. & ASS'NS ss. 3-114.1 (1993). The deemed
exchange will occur by operation of law, without any further act by the BGE
common shareholders. ID. The articles will provide for the cancellation of the
Constellation Energy stock owned by BGE immediately prior to the share exchange.
Draft Agreement, ss. 2.08.

           Completion of the proposed share exchange is subject to several
conditions. The share exchange must be approved by a vote of two-thirds of those
BGE shareholders entitled to vote on the matter. MD. CODE ANN., CORPS. & ASS'NS
ss. 3-105(d) (1998). In addition, formation of a holding company to own the BGE
stock will require an amendment of the Maryland Public Utilities Code. Draft
Agreement, ss. 1.01. Further, the Constellation Energy stock that will be issued
in the deemed exchange must be covered by a Registration Statement under the
Securities Act of 1933 and must be listed on the New York Stock Exchange.
Finally, the transaction is subject to the approval of various state and federal
regulatory agencies.

           The share exchange will not affect the holders of BGE preference
shares. The preference shares will not be subject to the share exchange but
instead will remain outstanding after the transaction.

           After completion of the share exchange, the stock of Constellation
Enterprises will be distributed to Constellation Energy, thereby separating the
regulated and unregulated businesses into two chains of corporations beneath the
single holding company.

                                    ANALYSIS

           SHARE EXCHANGE TAX-FREE TO HOLDERS OF BGE COMMON STOCK. In general,
transfers of property to a corporation in exchange for its stock qualify for
tax-free treatment if the transferors, in the aggregate, control the corporation
after the transfer. I.R.C. ss. 351(a). For this purpose, "control" means the
ownership of 80 percent of the corporation's voting stock and 80 percent of each
class of the corporation's nonvoting stock.
I.R.C. ss. 368(c).

           The proposed share exchange will meet the requirements for tax-free
treatment under section 351(a). The holders of BGE common stock will be deemed
by operation of law to have transferred property, in the form of their BGE
shares, to Constellation Energy. They will own all of the stock of Constellation
Energy immediately after the exchange. The Constellation Energy stock currently
owned by BGE will be cancelled as part of the transaction. Consequently, the
former holders of BGE common shares will "control" Constellation Energy, within
the meaning of section 368(c), immediately after the share exchange.

           NO TAX CONSEQUENCES TO HOLDERS OF BGE PREFERENCE STOCK. The share
exchange will not have any tax consequences to the holders of BGE preference
stock because those holders will not participate in the share exchange. In
general, the owner of property recognizes gain or loss on the property only upon
a "sale or other disposition" of the property. I.R.C. ss. 1001.

           BASIS AND HOLDING PERIOD OF CONSTELLATION ENERGY STOCK. When an owner
of property transfers that property to a corporation in a tax-free exchange to
which section 351(a) applies, the transferor's basis in the stock received is
determined by reference to the basis of the transferred property. I.R.C. 358(a).
This "substituted basis" rule ensures that the taxation of any unrealized
appreciation in the transferred property is merely deferred. Under section
358(a)(1), the transferor's basis in the transferred property serves as the
starting point for the basis of the stock received. The statute provides for
various adjustments to this basis when the transferor receives cash or property
other than stock of the transferee corporation, or when the transferor
recognized a loss on the exchange. SEE I.R.C. ss. 358(a)(1)(A) and (B). None of
these adjustments will apply in the present case. Therefore, the aggregate tax
basis of shares of Constellation Energy common stock received by a former BGE
common shareholder in the exchange will equal the shareholder's tax basis in the
shares of BGE common stock exchanged. I.R.C. ss. 358(a)(1).


<PAGE>
Baltimore Gas and Electric Company
March 3, 1999
Page 5


           The holding period of property received in a "substituted basis"
transaction includes the holding period of the property surrendered in the
exchange if the taxpayer held that property as a capital asset. I.R.C. ss.
1223(1). Because the deemed exchange of BGE common stock for Constellation
Energy common stock will be a substituted basis transaction, if a holder of BGE
common stock holds that stock as a capital asset, the holding period for that
stock will be tacked on to the holding period of the Constellation Energy stock
received in the exchange. ID.

           SHARE EXCHANGE TAX-FREE TO CONSTELLATION ENERGY AND BGE. A
corporation recognizes no gain or loss on its receipt of cash or other property
in exchange for stock of the corporation. I.R.C. ss. 1032(a). Section 1032(a),
by its plain terms, will apply to Constellation Energy's acquisition of
property, in the form of BGE common stock, in exchange for Constellation
Energy's own stock. Therefore, Constellation Energy will recognize no gain or
loss as a result of the share exchange.

           A corporation generally recognizes no gain or loss on the transfer of
its shares between shareholders because the transfer does not involve property
owned by the corporation. CF. I.R.C. ss. 1001. In certain cases, a purchaser of
a controlling interest in the stock of a corporation can elect to have the
transaction treated as a purchase of the corporation's assets. SEE GENERALLY
I.R.C. ss. 338. In the present case, Constellation Energy will not acquire the
BGE common stock by purchase, and would not make an election to treat the
transaction as a transfer of BGE's assets even if such an election were
possible. Therefore, the share exchange will not involve an actual or
constructive transfer of any assets owned by BGE, and BGE, consequently, will
recognize no gain or loss as a result of the share exchange.

           EFFECT OF SHARE EXCHANGE ON BGE AFFILIATED GROUP. The Internal
Revenue Code and Treasury regulations provide special rules for affiliated
groups of corporations. These rules allow an affiliated group to file a single,
consolidated tax return. The filing of consolidated returns can be advantageous
because it allows losses incurred by one member of the group to offset income
earned by another member of the group. In addition, the recognition of gain or
loss on transactions between members of the group is generally deferred as long
as the members remain affiliated and the transferred property remains within the
group.

           BGE and its direct and indirect subsidiaries currently comprise an
affiliated group within the meaning of section 1504(a) of the Code. (Unless
otherwise noted, references to Code sections are to sections of the Internal
Revenue Code of 1986, as amended.) That section defines "affiliated group" as a
group of corporations connected by one or more chains of at least 80 percent
stock ownership.


<PAGE>
Baltimore Gas and Electric Company
March 3, 1999
Page 6


           The identity of an affiliated group is generally determined by the
common parent of the group. SEE Treas. Reg. ss. 1.1502-75(d)(1) (a group remains
in existence if the common parent remains the common parent and at least one
subsidiary remains affiliated with it).

           Despite the general rule identifying an affiliated group by reference
to the common parent, in certain circumstances, an affiliated group can remain
in existence with a new common parent. One such circumstance is a transaction
that the regulations label a "reverse acquisition." Treas. Reg. ss.
1.1502-75(d)(3). A transaction is a reverse acquisition if it meets two
requirements. First, an acquiring corporation must acquire substantially all of
the assets of another corporation or an amount of stock of the acquired
corporation sufficient to cause the acquired corporation to become an affiliated
subsidiary of the acquiring corporation. Second, after the transaction, the
shareholders of the acquired corporation must own, by reason of their prior
ownership of acquired corporation stock, at least 50 percent of the stock of the
acquiring corporation. Treas. Reg. ss. 1.1502-75(d)(3)(i). If a reverse
acquisition occurs, any affiliated group of which the acquired corporation was
the common parent remains in existence after the transaction, with the acquiring
corporation as its new common parent. ID.

           Constellation Energy's acquisition of BGE common stock will meet each
of the two requirements of a reverse acquisition. First, as explained in more
detail below, Constellation Energy will acquire, pursuant to the share exchange,
an amount of BGE stock sufficient to cause BGE to become an affiliated
subsidiary of Constellation Energy. Second, because BGE's stock in Constellation
Energy will be cancelled pursuant to the share exchange, the Constellation
Energy stock that the current holders of BGE common stock will receive in the
exchange will constitute all of the outstanding stock of Constellation Energy.

           In acquiring all of the common stock of BGE, Constellation Energy
will acquire a sufficient amount of BGE stock to cause BGE to become an
affiliated subsidiary of Constellation Energy. The affiliation test of section
1504(a)(2) of the Code requires the ownership of 80 percent of the stock of the
affiliate, determined by both vote and value. In applying this test, certain
preferred stock is not treated as stock. I.R.C. ss. 1504(a)(4). Preferred stock
is excluded from the test if it (i) is nonvoting, (ii) is limited and preferred
as to dividends and does not participate in corporate growth to any significant
extent, (iii) has redemption and liquidation rights which do not exceed the
issue price of the stock (except for a reasonable redemption or liquidation
premium), and (iv) is not convertible into another class of stock. I.R.C. ss.
1504(a)(4)(A) through (D). As explained below, the preference shares in the 1993
and 1995 series meet each of these conditions. Therefore, these preference
shares will not be taken into account in applying the affiliation test of
section 1504(a)(2). It is possible, though less clear, that the 1973 series
preference shares would not be treated as stock for purposes of the affiliation
test. The issue is moot, however, because the 1973 series preference shares are
nonvoting and their value is only a small fraction of the value of the BGE
common shares. Thus, even if the 1973

series preference shares were treated as stock, the common stock acquired by BGE
would carry all of the voting power of the BGE stock and would have a value of
more than 80 percent of the value of all shares that could be treated as stock
for purposes of the affiliation test.

           Although BGE's preference shares have limited and contingent voting
rights, the shares are treated as nonvoting stock for purposes of section
1504(a)(4)(A) of the Code. For this purpose, stock is voting stock if its
holders have the present ability to elect directors of the corporation. The
ability of preferred shareholders to vote on matters other than the election of
directors does not make their stock voting stock for purposes of the affiliation
test. ERIE LIGHTING CO. V. COMMISSIONER, 93 F.2d 883 (1st Cir. 1937). In
addition, the ability of the holders of preference shares to vote for directors
if BGE fails to pay dividends on those shares for at least one year does not
mean that the shares are currently voting shares. The classification of stock as
voting stock depends on the rights of the holders during the period in issue.
VERMONT HYDRO-ELECTRIC CORP. V. COMMISSIONER, 29 B.T.A. 1006 (1934). If
preferred stock entitles its holders to vote after a failure to pay dividends,
the stock is treated as voting stock only after the contingency arises. ID.
Because no deficiency currently exists in the payment of dividends on BGE
preference shares, those shares constitute nonvoting stock within the meaning of
section 1504(a)(4)(A).

           The BGE preference shares in the 1993 and 1995 series are limited and
preferred as to dividends and do not participate in corporate growth to any
significant extent. These shares carry a fixed dividend that must be paid before
BGE can pay dividends on its common shares. Thus, the shares are limited and
preferred as to dividends. Neither the dividend feature nor any other term of
the shares enables the holders to participate in corporate growth to a
significant extent. The shares do not participate in dividends with the common
stock. The stated dividend rate serves as a ceiling. Although the terms of the
shares do provide for a small redemption premium in certain circumstances, that
premium is separately addressed under section 1504(a)(4)(C). As explained below,
the redemption premium provided under the terms of the shares in the 1993 and
1995 series should be viewed as "reasonable," within the meaning of that
section. Consequently, the redemption premium should not be viewed as affording
significant participation in corporate growth for purposes of section
1504(a)(4)(B).

           The liquidation rights of the preference shares do not exceed the
issue price, and the redemption rights provided under the terms of the shares in
the 1993 and 1995 series exceed the issue price only by a reasonable redemption
premium. Upon liquidation, the holders of the preference shares will receive
only the par value, at which the shares were issued, plus accrued dividends.
Although the holders of preference shares could receive a premium on redemption,
in addition to par value plus accrued dividends, these premiums, at least in the
case of the shares in the 1993 and 1995 series, should be viewed as
"reasonable," within the meaning of section 1504(a)(4)(C).

           Regulations issued under section 305 of the Code provide the best
available guidance on when a redemption premium is reasonable. Neither the
Treasury Department nor the courts have defined the term "reasonable redemption
premium" specifically for the purpose of section 1504(a)(4)(C). When Congress
enacted that section in 1984, however, the phrase "reasonable redemption
premium" was significant under section 305 and the accompanying regulations. In
the absence of special rules, redemption premiums could be used as a means to
convert what would otherwise be dividend income, taxed at ordinary rates, into
capital gain recognized on redemption. Section 305 and the accompanying
regulations address this issue by requiring the holder of the preferred stock,
in certain circumstances, to include the premium in income prior to redemption.
Before their amendment in 1995, the regulations provided that this accrual rule
did not apply to a "reasonable redemption premium." Treas. Reg. ss.
1.305-5(b)(2) (prior to amendment by T.D. 8643). For this purpose, a redemption
premium was considered reasonable if it was "in the nature of a penalty for
premature redemption of the preferred stock and if such premium does not exceed
the amount the corporation would be required to pay for the right to make such
premature redemption under market conditions existing at the time of issuance."
ID. The regulations provided a safe harbor under which a redemption premium was
considered reasonable if it did not exceed 10 percent of the issue price of the
stock and the stock was not redeemable for at least 5 years after issuance. ID.
Amendments to the regulations adopted in 1995 eliminated the exception for
reasonable redemption premiums. The regulations now require accrual of a
redemption premium if two conditions are met. First, the premium must exceed a
de minimis amount determined by reference to the original issue discount rules
that require the accrual of interest on debt instruments. Treas. Reg. ss.
1.305-5(b)(1). Second, in the case of stock that is callable at the option of
the issuer, accrual is required only when the issuer is likely to exercise the
call option. Treas. Reg. ss. 1.305-5(b)(3)(i). In general, exercise of the call
option is not considered likely if doing so would not reduce the yield on the
stock. Treas. Reg. ss. 1.305-5(b)(3)(ii). A call premium on redemption that
would reduce the yield cannot be viewed as a penalty for premature redemption.
Notice of Proposed Rulemaking and Notice of Public Hearing, Distributions of
Stock and Stock Rights, CO-8-91, 1994-2 C.B. 844, 845. Therefore, the only
circumstances in which a call premium would be subject to accrual - when
redemption would reduce the yield of the stock - would necessarily be
circumstances in which the premium could not be viewed as a reasonable
prepayment penalty. Consequently, the exception for reasonable redemption
premiums was no longer necessary. Nonetheless, the definition of reasonable
redemption premium in the prior regulations, including the safe harbor
provision, provide the best evidence of the concept Congress had in mind when it
used that term in section 1504(a)(4).

           In assessing the reasonableness of the redemption premiums provided
under the terms of BGE's preference shares, separate analyses apply to the
shares in the 1973 shares and those in the 1993 and 1995

series. The redemption premiums provided for the shares in 1993 and 1995 series
meet the safe harbor test and thus are clearly reasonable within the meaning of
the prior section 305 regulations. Because the shares in the 1973 series were
redeemable from the time of issuance, the safe harbor does not apply to the
redemption premium provided for those shares. Therefore, assessing the
reasonableness of the redemption premium on those shares would require a factual
inquiry into such factors as the market conditions when the shares were issued.
As explained below, however, this factual inquiry is unnecessary in the present
case because the Constellation Energy's acquisition of the BGE common shares
would cause BGE to become an affiliated subsidiary of Constellation Energy even
if the BGE 1973 series preference shares, which Constellation Energy will not
acquire, are treated as stock for purposes of the affiliation test.

           The safe harbor test provided in the prior section 305 regulations
will apply to the redemption premiums provided under the terms of the 1993 and
1995 series preference shares. The maximum premium that might be paid on the
redemption of shares in these series would be well below 10 percent of the par
value at which the shares were issued. The 7.125% Cumulative Preference Shares,
1993 Series provide the highest possible redemption premium. At $3.56, this
premium is only 3.56 percent of the $100 issue price. Further, the shares in the
1993 and 1995 series do not become callable until ten years after issuance.
Although the redemption premiums in each case exceed the de minimis threshold
that applies for purposes of the original issue discount rules, SEE I.R.C. ss.
1273(a)(3), that should not prevent the premiums from being treated as
reasonable. In each case, exercise by BGE of its option to call the preference
shares would increase the yield on the shares. Therefore, the amended
regulations under section 305 would not require accrual of the premiums, even
though they exceed the applicable de minimis threshold. The fact that exercise
of the call option would increase the yield on the shares illustrates that the
redemption premium is in the nature of a prepayment penalty. Therefore, the
premiums are reasonable in amount, based on the safe harbor provided in the
regulations in effect under section 305 when Congress enacted section
1504(a)(4).

           The redemption premium provided for the shares in the 1973 series may
also be viewed as reasonable under the general rule of the prior section 305
regulations. Again, the regulations provided that a redemption premium was
considered reasonable if it was "in the nature of a penalty for premature
redemption of the preferred stock and if such premium does not exceed the amount
the corporation would be required to pay for the right to make such premature
redemption premium under market conditions existing at the time of issuance."
Treas. Reg. ss. 1.305-5(b)(2) (prior to amendment by T.D. 8643). The fact that
the shares were immediately redeemable strongly suggests that the stated premium
was intended to compensate the holder for the loss of the dividends he would
have earned had the stock not been redeemed. Nonetheless, concluding that the
redemption premium provided on the 1973 series preference shares was reasonable
within the meaning of the prior section 305 regulations would require an inquiry
into

Baltimore Gas and Electric Company

Page 10


market conditions existing in 1973. As explained below, such an inquiry is
unnecessary in the present case.

           The BGE preference shares are not convertible into shares of any
other class of BGE stock. Therefore, the preference shares meet the fourth and
last condition for being disregarded in applying the affiliation test of section
1504(a)(2). SEE I.R.C. ss. 1504(a)(4)(D).

           The preceding analysis demonstrates that the BGE preference shares in
the 1993 and 1995 series meet all of the conditions specified in section
1504(a)(4) and thus are disregarded in applying the affiliation test of section
1504(a)(2). The shares in the 1973 series may also meet the conditions for being
disregarded. If all of the preference shares were disregarded, the BGE common
shares that Constellation Energy will acquire in the share exchange would
constitute all of the stock taken into account for purposes of the affiliation
test. Even if the 1973 series preference shares were treated as stock, the BGE
common shares would still carry all of the voting power of the BGE stock and
would represent well more than 80 percent of the BGE stock by value. Because the
1973 series preference shares may be redeemed at any time for $101, their value
cannot exceed the prescribed redemption price. There are currently 200,000 of
these shares outstanding. Thus, they have an aggregate value of $20,200,000
(200,000 x $101). By contrast, 149,556,416 BGE common shares are outstanding. A
recent trading price of those shares (at mid-day on February 18, 1999) was
$26.88. Therefore, at that price, the common shares have an aggregate value of
approximately $4,040,276,462 (149,556,416 x $26.88). Even if the 1973 series
preference shares were treated as stock, the BGE common shares would constitute
approximately 99.5 percent of the total BGE stock by value (4,020,076,462 /
(4,020,076,462 + $20,200,000) = .995) Thus, regardless of whether the 1973
series preference shares are treated as stock, Constellation Energy's
acquisition of all of the BGE common shares will cause BGE to become an
affiliated subsidiary of Constellation Energy.

           Because Constellation Energy's acquisition of BGE common stock will
constitute a reverse acquisition, within the meaning of section 1.1502-75(d)(3)
of the regulations, the share exchange will not terminate the existence of the
BGE affiliated group. Instead, the group will remain in existence with
Constellation Energy as the new common parent. Treas. Reg. ss.
1.1502-75(d)(3)(i).

                                     OPINION

           For the reasons explained above, assuming the accuracy of the facts
stated in this letter and the representations made in your letter to us of this
date, in our opinion:


<PAGE>
Baltimore Gas and Electric Company
March 3, 1999
Page 11


           (1) No income, gain or loss will be recognized by a BGE common
           shareholder upon the deemed exchange solely of such holder's BGE
           common stock solely for Constellation Energy Common stock. I.R.C.
           ss. 351(a).

           (2) No income, gain or loss will be recognized on the share exchange
           by holders of outstanding shares of BGE preference stock with respect
           to their shares because they will not participate in the share
           exchange and will keep their BGE preference stock. CF. I.R.C. ss.
           1001.

           (3) The aggregate tax basis of shares of Constellation Energy common
           stock received by a former BGE common shareholder in the exchange
           will equal the shareholder's tax basis in the shares of BGE common
           stock exchanged. I.R.C. ss. 358(a)(1). The holding period for the
           Constellation Energy common stock received will include the holding
           period for the BGE common stock exchanged to the extent that such
           shares were held as capital assets at the time the share exchange
           occurred. I.R.C. ss. 1223(1).

           (4) No gain or loss will be recognized by Constellation Energy or BGE
           on account of the share exchange or the issuance of shares of
           Constellation Energy common stock to the former BGE shareholders
           pursuant to the Agreement and Plan of Share Exchange. I.R.C. ss.
           1032(a).

           (5) The share exchange will not result in the termination of the
           existence of the affiliated group of corporations of which BGE has
           been the common parent, and Constellation Energy will be included in
           such affiliated group of corporations of which Constellation Energy
           will become the new common parent. Treas. Reg. ss. 1.1502-75(d)(3).

           The opinions stated above are based on the Code, Treasury
regulations, court decisions, and published rulings of the Internal Revenue
Service currently in effect. Each of these authorities is subject to change and
any such changes could affect the validity of the above opinions. To the extent
that the opinions address the federal income tax consequences of the share
exchange to holders of BGE common stock, the opinions assume that the
shareholders are not subject to special treatment because of unique
circumstances, as could be the case, for example, for foreign corporations or
individuals who are not citizens or residents of the United States.

           We hereby consent to (i) the filing of this opinion with the
Securities and Exchange Commission as an exhibit to the registration statement
regarding the issuance of Constellation Energy common stock and (ii) the
reference to our firm under the heading "Material Federal Income Tax
Consequences" in the Proxy Statement/Prospectus that constitutes a part of the

Dear Shareholder:

As of March 26, 1999, we had not received your proxy card for the 1999 annual
shareholders meeting to be held April 16th.

We appreciate the support of our shareholders and encourage you to vote your
shares, regardless of the size of your holdings. We have, therefore, enclosed a
second proxy card so that you can vote your shares. Whether or not you plan to
attend the meeting, please complete and return the enclosed proxy card to ensure
that your vote will be counted at the meeting.

Our initial mailing to you also included a proxy statement and prospectus, and
our 1998 annual report to shareholders. If you would like to receive a duplicate
copy of these documents, simply contact one of our shareholder representatives
in metropolitan Baltimore at 410-783-5920, within Maryland at 1-800-492-2861, or
outside Maryland at 1-800-258-0499.


Sincerely,
