"We are undertaking a number of initiatives to move costs towards competitive

Executive Officer.

CEG Fourth Quarter Earnings

The $532.6 million special costs recognized in the fourth quarter include two
previously announced costs, the termination of the Goldman Sachs power business
services agreement, and the sale of Constellation Energy Group's Guatemalan
operations, together totaling $268.1 million. The remaining $264.5 million
relates primarily to workforce reduction initiatives, plans to monetize non-core
assets, and the termination of several power plant development projects.

"The special costs recognized in the fourth quarter are the result of rigorous
analysis coupled with decisive action to accelerate the process of monetizing
the value of non-core assets. This reflects a change of intent regarding certain
investments including our real estate portfolio, senior living facilities, and
our international investments," Constellation Energy Group CEO Shattuck said.

Constellation Energy Group also recognized a minimum pension liability in the
fourth quarter, which did not affect earnings but reduced equity by $44.7
million. The recognition of a minimum pension liability was caused by the
combination of decreases in plan assets due to declining equity markets in 2001
and an increased pension liability primarily due to the aforementioned workforce
reduction initiatives.

Earnings per share for Constellation Energy Group's business segments were as
follows:

CEG Fourth Quarter Earnings
Page 3

The Merchant Energy business earned $0.31 per share excluding special costs
versus $0.32 per share in the fourth quarter of 2000. The negative impact of
declining California power prices on our power projects was largely offset by
accretion from the termination of the Goldman Sachs power business services
agreement.

Baltimore Gas and Electric's regulated electric and gas businesses declined by
$0.01 per share, from $0.14 per share in the fourth quarter of 2000 to $0.13 per
share in the fourth quarter of 2001, excluding special items. The unfavorable
impact of milder weather was largely offset by a reduction in interest expense.

Earnings for the Other Nonregulated businesses were $0.02 excluding special
costs, compared with $0.11 per share in the fourth quarter of 2000. The $25.1
million, or $0.15 per share, reduction in net income attributable to lower gains
on the sale of securities in the fourth quarter of 2001 was partially offset by
the favorable impact of increased occupancy in our health services facilities.

An addendum detailing the special costs recognized in 2001 is attached.

Contract Termination Related Costs  - $224.8 million
- ----------------------------------------------------
Constellation Energy Group announced the termination of its power business
services agreement with Goldman Sachs on October 26, 2001. Constellation Energy
Group paid Goldman Sachs a total of approximately $355 million, comprising
$196.7 million to terminate the power business services agreement with our power
marketing operation and $159 million previously recognized as a payable for
services rendered under the agreement.

In addition, we (Constellation Energy Group) terminated a software agreement
wherein Goldman Sachs would provide maintenance, support, and minor upgrades to
our risk management and trading system. We recognized $17.6 million in expense
in the fourth quarter of 2001 representing the unamortized prepaid costs related
to this agreement. Finally, we incurred approximately $10.5 million in
employee-related

                                     (more)

expenses and banking and legal advisory fees in connection with the termination
of the Goldman Sachs agreement. In total, we recognized expenses of
approximately $224.8 million in the fourth quarter of 2001 relating to the
termination of our relationship with Goldman Sachs.

Loss on Sale of Guatemalan Operation - $43.3 million
- ----------------------------------------------------
On November 8, 2001, we sold our Guatemalan power plant operations to an
affiliate of Duke Energy International, LLC, the international business unit of
Duke Energy. Through this sale, Duke Energy acquired Grupo Generador de
Guatemala y Cia., S.C.A., which owns two generating plants at Esquintla and Lake
Amatitlan in Guatemala. The combined capacity of the plants is 167 megawatts. We
decided to sell our Guatemalan operations to focus our efforts on our core
energy businesses. We recorded a $43.3 million pre-tax loss on this sale.

Workforce Reduction Costs -- $105.7 million
- -------------------------------------------
In the fourth quarter of 2001, we recognized costs to reduce our workforce
through both voluntary and involuntary means. The purpose of these programs was
to reduce our operating costs to more competitive levels.

Voluntary Special Early Retirement Programs (VSERP)
- ---------------------------------------------------
We offered several Voluntary Special Early Retirement Programs (VSERP) to
employees of certain of our companies. The first group of these programs offered
enhanced early retirement benefits to employee's age 55 or older with 10 or more
years of service. The second group of these programs offered enhanced early
retirement benefits to employees in certain business units age 50 to 54 with 20
or more years of service.

Since employees electing to participate in the age 55 or older VSERP had to make
their elections by the end of 2001, the cost of that program was reflected in
2001. The $70.1 million in the above table reflects the portion of the total
cost of that program charged to expense for the 507 employees that elected to
participate. The total cost of the VSERP was $83.8 million, however $13.7
million was deferred as a regulatory asset related to Baltimore Gas and Electric
Company's gas business.

Settlement and Curtailment Charges
- ----------------------------------
In connection with the age 55 or older VSERP, a significant number of the
participants in our nonqualified pension plans are retiring. As a result, we
recognized a settlement loss of $10.5 million and a curtailment loss of $5.8
million for those plans in accordance with Statement of Financial Accounting
Standards (SFAS) No. 88 Employers' Accounting for Settlements and Curtailments
of Defined Benefit Pension Plans and for Termination Benefits. We also expect
that a significant number of retiring employees under our qualified, basic
pension plan will elect to receive their pension benefit in the form of a
lump-sum payment in 2002. We expect these lump-sum payments will exceed annual
plan service cost and interest expense, thereby triggering an additional
settlement loss in 2002 estimated to be approximately $20 million.

Involuntary Severance Accrual
- -----------------------------
Our workforce reduction plan identified 435 jobs to be eliminated over and
above position reductions expected to be satisfied through the age 55 and over
VSERP elections. We will not know how many employees will elect the age 50-54
VSERP and how many employees will be involuntarily severed until the election
period for the VSERP ends on February 15, 2002. In accordance with Emerging
Issues Task
                                     (more)

Force Consensus No. 94-3, Liability Recognition for Certain Employee Termination
Benefits and Other Costs to Exit an Activity (including Certain Costs Incurred
in a Restructuring), the Company recognized a liability of $25.1 million at
December 31, 2001 for the targeted number of involuntary terminations that will
result if no employees elect the age 50 to 54 VSERP. The $19.3 million in the
table above represents involuntary severance charged to expense in 2001 in
connection with the Company's employee reduction programs. BGE deferred $5.8
million of the total cost as a regulatory asset related to its gas business.
We will accrue any additional cost in excess of the 2001 involuntary severance
accrual for those eligible participants that elect the 50 to 54 VSERP in 2002.


Real Estate, Senior Living, and Latin American Investments - $107.3 million
- ---------------------------------------------------------------------------
In the fourth quarter of 2001, we decided to focus management efforts and
capital on our core domestic energy businesses. We will move forward with a plan
to sell a number of non-core businesses and investments in 2002 and otherwise
accelerate our exit strategies. The book value of these investments is higher
than expected proceeds from the sale of these investments on an accelerated
basis. As a result of the decision to accelerate our exit from these investments
rather than continue to pursue prior strategies which required additional
investment of capital, risk, and management attention over long periods of time,
we are required to recognize impairments under SFAS No. 121, Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed of.

Real Estate
- -----------
We decided to sell six real estate projects in 2002 without further development
and to accelerate the exit strategy for two other real estate projects. Our
revised exit strategy for these non-core assets represents a change in intent
requiring the write-down of these assets to their expected fair value under SFAS
No. 121. The impaired projects include approximately 1300 acres of land holdings
in various stages of development located at seven sites in the Central Maryland
region and an operating waste water treatment plant located in Anne Arundel
County, Maryland.

Senior Living Facilities
- ------------------------
We also own a portfolio of 18 assisted living facilities that we intend to sell
in 2002. We adjusted our investment, to its fair value.

Latin American Investments
- --------------------------
We will work to sell our interest in a Panamanian electric distribution company
and our interest in a Bolivian generation concession. While we believe a sale of
the Panama investment can be completed by mid-to-late 2003, we had to write down
this investment to its expected fair value under SFAS No. 121. We also recorded
an other than temporary decline in our equity method Bolivian investment under
Accounting Principles Board Opinion (APB) No. 18, The Equity Method of
Accounting for Investments in Common Stock. This decline in value resulted from
a deterioration of our investment's position in the dispatch curve of its
capacity market.

Domestic Power Projects - $46.9 million
- ---------------------------------------
Due to expected excess generation capacity in most domestic markets, we are
terminating development of all planned projects not currently under
construction. We are recognizing a $40.8 million impairment adjustment under
SFAS No. 121 associated with the termination of planned development projects in
Texas,

                                     (more)

California, Florida and Massachusetts. The majority of these costs relate to the
impairment of four turbines no longer  expected  to be placed in  service.  In
accordance with the provisions of APB No. 18, we also  recognized  $6.1 million
for an other than temporary  decline in the value of our  investment in a waste
burning power plant in Michigan where operating cash flows are not sufficient to
pay  existing  debt service and where we are not likely to recover our equity
investment.

Financial Investments - $4.6 million
- ------------------------------------
Our financial investments business recorded a $4.6 million write-down of its
investment in a leased aircraft due to the other than temporary decline in the
estimated residual value of used airplanes as a result of the September 11, 2001
terrorist attacks and the general downturn in the aviation industry.
