eligible compensation on the date as of which benefits become payable.  (b)           Retirement
benefits.  (i)            Eligibility

A participant shall be eligible to retire under this Plan on or after

preceding his/her Normal Retirement Date, if on his/her Severance From Service
Date and while a participant he/she has attained (1) age 55 and has accumulated
at least 10 years of Credited Service; or (2) age 60 and has accumulated at
least one year of Credited Service.  (ii)           Computation
of retirement benefits. 
A participant who is eligible to retire under this Plan will be entitled
to supplemental pension retirement benefits under this Plan, which will be
calculated as set forth below on the participants Benefit Start Date:  (1)           add the Annual Base Salary and the
Average Incentive Award,  (2)           divide the sum by 12,  (3)           multiply this dollar amount by the
appropriate percentage, determined as follows: 
Chairman of the Board of  5 
   Constellation Energy Group60%; all other participants (by completed years of
Credited Service) 1 through 9  3% per year; 10 through 19  40%; 20 through 24
 45%; 25 through 29  50%; and 30 or more  55%,  (4)           multiply this dollar amount by the
Early Receipt Reduction Factor; provided, however, if the participant is age 62
or older, such factor shall be one (1),  (5)           subtract from this dollar amount the
charges relating to coverage for a preretirement survivor annuity in excess of
50%, and for a post-retirement survivor annuity in excess of 50%, and  (6)           subtract from the remainder the net
amount payable to the participant under the Pension Planon the participants Benefit Start Date,
assuming a 50% spousal joint and survivor annuity for a married participant(if
the participant is not eligible to commence monthly Pension Plan payments on
the participants Benefit Start Date, the participants benefit will be
unreduced for Pension Plan payments until the date the participant is first
eligible to commence monthly Pension Plan payments),or, if the participant elects a lump sum under the PEP
provisions of the Pension Plan, the monthly amount that would have been payable
under the Pension Plan as a life annuity for a single participant or as a 50%
spousal joint and survivor annuity for a married participant, as of the Benefit
Start Date under this Plan.  (iii)          Form
of payout of retirement benefits.  Each participant entitled to supplemental pension retirement
benefits will receive his/her supplemental pension retirement benefits payout
in the form of a monthly payment, unless the participant makes a valid election
to receive his/her supplemental pension retirement benefits payout in the form
of a lump sum.  A participant may elect to
receive his/her supplemental pension retirement benefits payout in  6 
   the form of a lump sum by
submitting to the Plan Administrator a signed Lump Sum Election Form.  On such Form, the participant may elect to
rollover such payout directly to the Nonqualified Deferred Compensation
Plan.  The Form must be received by the
Plan Administrator before the beginning of the calendar year during which the
participants Severance From Service Date occurs.  The election to receive a payout in the form of a lump sum, or to
rollover such payment to the Nonqualified Deferred Compensation Plan, may be
revoked at any time before the beginning of the calendar year during which the
participants Severance From Service Date occurs, by submitting to the Plan
Administrator a signed Lump Sum Revocation Form.  (iv)          Amount,
timing, and source of monthly retirement benefit payout.  A participant entitled to monthly
supplemental pension retirement benefits will receive monthly payments equal to
the amount determined under paragraph (b)(ii). 
Such payments shall commence effective with the first of the month
following the participants Severance From Service Date.  If such participant receives (or would have
received but for the Internal Revenue Code Limitations) cost of living
adjustment(s) under the Pension Plan, the monthly payments hereunder will be
automatically increased based on the percentage of, and at the same time as, such
adjustment(s).  Monthly payments
hereunder shall permanently cease upon the death of the participant, effective
with the monthly payment for the month following the month of the participants
death.  Monthly payments hereunder shall
be made in accordance with the provisions of the Rabbi Trust and, to the extent
not paid under the terms of the Rabbi Trust, from general corporate assets.  (v)           Amount,
timing, and source of lump sum retirement benefit payout.  A participant entitled to a lump sum
supplemental pension retirement benefit will receive a lump sum payment.  This lump sum payment will be calculated by
a certified actuary and will be equal to the present value of an immediate
annuity including the estimated present value of post-retirement supplemental
survivor annuity  7 
   benefits described in
Section 6, and reflecting the present value of any deferred Pension Plan
payments using (1) the supplemental pension retirement benefit amount
calculated under paragraph (b)(ii), which is expressed as a monthly amount, (2)
the Interest Rate computed on the participants Benefit Start Date, and (3) the
Mortality Table.  Such lump sum payment
shall be made within 60 days after the participants Severance From Service
Date, and shall either be paid to the participant, or rolled over to the
Nonqualified Deferred Compensation Plan pursuant to the participants election
under (b)(iii).  The lump sum payment
shall be made in accordance with the provisions of the Rabbi Trust and, to the
extent not paid under the terms of the Rabbi Trust, from general corporate
assets.  A participant who receives or
rolls over a lump sum payment shall not be entitled to any cost of living or
other pension payment adjustments or to post-retirement survivor annuity
coverage under the Plan.  (vi)          Death
of participant entitled to lump sum payout.  In the event of the death of a participant
after his/her Severance From Service Date and before the participant receives
or rolls over the lump sum payment under paragraph (b)(v), such lump sum
payment shall be made to the participants surviving spouse (as defined in
Section 6(i)).  The lump sum payment
shall be the same amount and made at the same time and from the same sources as
set forth in paragraph (b)(v).  If there
is no surviving spouse at the date of the participants death, no payments
shall be made pursuant to Sections 5 or 6. 
A surviving spouse who receives a lump sum benefit under this paragraph
(b)(vi) shall not be entitled to any cost of living or other pension payment
adjustments or to post-retirement survivor annuity coverage under the Plan.  (c)                           Entitlement to benefit upon happening of certain
events.  (i)            Computation
of gross accrued benefit. 
The computation of the gross accrued supplemental  8 
   pension benefit for a
participant as of the date of the computation will be made as follows:  (1)           add the Annual Base Salary and the
Average Incentive Award,  (2)           divide the sum by 12, and  (3)           multiply this dollar amount by the
appropriate percentage, determined as follows: 
Chairman of the Board of Constellation Energy Group  60%; all other
participants (by completed years of Credited Service as of the date of the
computation) 1 through 9  3% per year; 10 through 19  40%; 20 through 24 
45%; 25 through 29  50%; and 30 or more  55%.  (ii)           Computation
of net accrued benefit. 
The computation of the net accrued supplemental pension benefit for a
participant as of the date of the computation will be made by subtracting from
the gross accrued benefit determined under paragraph (c)(i) the amount of the
participants Gross Pension under the Pension Plan determined as of the date of
the computation and assuming that monthly payments of such Gross Pension begin
on the first of the month after the later of reaching age 62 or the date of the
computation.  If the participant is not
eligible for payment of a Gross Pension under the Pension Plan, the
participants Accrued Gross Pension determined as of the date of the
computation shall be substituted for the Gross Pension described above, with
the appropriate reduction for early receipt applied as if the participant were
eligible to begin payment of his Accrued Gross Pension on the first of the
month after the later of reaching age 62 or the date of the computation.  (iii)          Satisfaction
of requirements.  A
participant who has satisfied the age and Credited Service requirements set
forth in Section 5(b)(i) while eligible as set forth in Section 4, but who the
Committee determines does not retire under the Plan due to Demotion,
Termination From Employment With Constellation Energy Group, or the withdrawal
of a participants eligibility to participate  9 
   under Section 5,  shall be entitled to his/her net accrued
supplemental pension  benefit.  The effective date of the Demotion,
Termination From Employment With Constellation Energy Group, or eligibility
withdrawal event shall be the date of such Demotion, Termination From
Employment With Constellation Energy Group, or eligibility withdrawal.  (iv)          Other
events.  A participant,
regardless of his/her age and years of Credited Service, shall be entitled to
his/her net accrued supplemental pension benefit upon the happening of any of
the following entitlement events, but only if such entitlement event occurs
while a participant and before a participant retires under this Plan:  (1)           Change
in Control.  A Change in
Control, followed within two years by the participants Demotion, a
participants Termination From Employment With Constellation Energy Group, or
the withdrawal of the participants eligibility to participate under the Plan,
is an entitlement event.  The effective
date of the entitlement event shall be the date of the Demotion, Termination
From Employment With Constellation Energy Group, or eligibility withdrawal.  (2)           Plan
amendment.  A Plan
amendment that has the effect of reducing a participants gross accrued
supplemental pension benefit is an entitlement event.  In determining whether such a reduction has occurred, the
participants gross accrued supplemental pension benefit calculated on the day
immediately preceding the effective date of the amendment shall be compared to
the participants gross accrued supplemental pension benefit calculated on the
effective date of the amendment.  An
amendment that has the effect of reducing future benefit accruals is not an
entitlement event.  It is intended that
an entitlement event under this paragraph (c)(iv)(2) will occur only with
respect to those amendments that are substantially similar to amendments that
are  10 
   prohibited by Internal
Revenue Code section 411(d)(6) with respect to qualified pension plans.  The effective date of the entitlement event
shall be the effective date of the Plan amendment.  (3)           Involuntary
Demotion, Termination From Employment With Constellation Energy Group, or
eligibility withdrawal without Cause.  A participants involuntary Demotion or involuntary Termination
From Employment With Constellation Energy Group without Cause, or the
withdrawal of a participants eligibility to participate under Sections 5 or 6
of the Plan without Cause, is an entitlement event.  The effective date of the entitlement event shall be the
effective date of the participants involuntary Demotion or involuntary
Termination From Employment With Constellation Energy Group without Cause, or
the eligibility withdrawal without Cause.  (v)           Form
of benefit payout.  Each participant
entitled to a payout under this paragraph (c) will receive such payout in the
form of a lump sum payment.  (vi)          Amount,
timing, and source of benefit payout.  A participant entitled to a payout of his/her net accrued
benefit, as a result of the occurrence of an event described in paragraphs
(c)(iii), (c)(iv)(1), (2), or (3) will be entitled to a lump sum benefit.  This lump sum benefit will be calculated by
a certified actuary as the present value, determined as of the date of payment,
of an annuity beginning at age 62  (or
the participants actual age, if the participant is older than age 62 on the
date the lump sum benefit is payable), including the estimated present value of
post-retirement survivor annuity benefits described in Section 7, using (1) the
net accrued benefit amount calculated under paragraph (d)(ii) on the effective
date of the entitlement event, which is expressed as a monthly amount, (2) the
Interest Rate computed on the date the lump sum benefit is payable, and (3) the
Mortality Table.  The lump sum benefit
shall be payable as of the participants Severance From service Date, and  11 
   shall be made within 60 days
after such date in accordance with the provisions of the Rabbi Trust and, to
the extent not paid under the terms of the Rabbi Trust, from general corporate
assets.  A participant who receives a
lump sum benefit under this paragraph (c)(vi) shall not be entitled to any cost
of living or other pension payment adjustments or to preretirement or
post-retirement survivor annuity coverage.  (vii)         Death
of participant entitled to lump sum payout.  In the event of the death of a participant
after the occurrence of an event described in paragraphs (c)(iii), (c)(iv)(1),
(2), or (3) and before the participant receives the lump sum payment under
paragraph (c)(v), such lump sum payment shall be made to the participants
surviving spouse (as defined in Section 6(i)). 
The lump sum payment will be calculated by a certified actuary and will
be equal to 100% of the lump sum that would have been paid to the participant
under paragraph (vi), as of the date on which the lump sum is payable under
this paragraph (vii), provided that the participants date of death is on or
after his/her Severance From Service Date. 
If the participants date of death is before his/her Severance From
Service Date, 50% shall be substituted for 100% in the preceding sentence. The
lump sum benefit shall be payable as of the earlier of the participants
Severance From Service Date or date of death, and shall be made within 60 days
after such date in accordance with the provisions of the Rabbi Trust and, to
the extent not paid under the terms of the Rabbi Trust, from general corporate
assets.  If there is no surviving spouse
at the date of the participants death, no payments shall be made pursuant to
Sections 5 or 6.  A surviving spouse who
receives a lump sum benefit under this paragraph (c) (vii) shall not be
entitled to any cost of living or other pension payment adjustments or to
preretirement or post-retirement survivor annuity coverage under the Plan.  6.             Supplemental Survivor Annuity Benefit.  (a)           Survivor annuity
benefit.   12 
   (i)            Eligibility
for survivor annuity benefit. 
Following the death of a participant who is fully vested under the
Pension Plan, a supplemental survivor annuity may be paid to the participants
surviving spouse until the death of that spouse, using the Survivor Annuity
Percentage.The participant will
not bear the cost of up to a 50% survivor annuity benefit, but will bear the
cost of a survivor annuity benefit in excess of 50%.  For purposes of this Section 6(a), a participants surviving
spouse is the individual married to the participant on the date of the
participants death.  If there is no
surviving spouse, or if the participant or the participants spouse previously
received or is entitled to receive either a lump sum payment under Section 5,
or a benefit under the Senior Executive Supplemental Plan, no supplemental
survivor annuity will be payable.  (ii)           Computation
of survivor annuity benefit. 
The amount of the supplemental survivor annuity will be determined as
follows:  (1)           if the participants Benefit Start
Date occurred prior to the date of death:  (a)           begin with the monthly pension
benefit (under Section 5(b) of this Plan) that the participant was receiving
prior to the date of death, and  (b)           multiply this dollar amount by the
Survivor Annuity Percentage.  (2)           otherwise:  (a)           Unless the participant elected the
alternative in-service death benefit in section (b) below:  (1)           begin with the monthly Early Retirement pension benefit
(under both the Pension Plan and Section 5(b) of this Plan) to which the
participant would have been entitled to receive if:  the participant had been
retired at the later of age 60 or his/her  13 
   actual age on the date of
death for purposes of computing the Early Receipt Reduction Factor,  (2)           multiply this dollar amount by the Survivor Annuity
Percentage,  (3)           subtract from the product the net amount, if any, of the
survivor annuity provided on behalf of the participant under the Pension Plan
if the participant is participating in the Traditional Pension Plan, or the
monthly annuity that would have been provided to the participants spouse
assuming that he or she had been designated as the participants beneficiary
and had chosen to receive a survivor benefit in the form of a monthly annuity,
if the participant is participating in the PEP, and  (4)           subtract from this dollar amount the charges relating to
coverage (under both the Pension Plan and this Plan) for a preretirement
survivor annuity in excess of 50%.  (b)           If the participant was a participant
in the Pension Equity Plan option of the Pension Plan and elected this
alternative in-service death benefit by December 31 of the year prior to
his/her death or during the 2001 initial election period established by the
Plan Administrator  (1)           calculate the benefit under the
Constellation Energy Group Benefits Restoration Plan that would have been
payable to the surviving spouse if the participant were a participant in that
plan and (2)           that dollar amount will be paid to
the surviving spouse only in the form of a lump sum from this Plan.  14 
   (iii)          Form
of payout of survivor annuity benefits. Unless the participant
made a valid election by December 31 of the year prior to his/her death or
during the 2001 initial election period established by the Plan Administrator,
to have the survivor benefits paid in a lump sum, each  surviving spouse entitled to a supplemental
survivor annuity benefit will receive his/her survivor annuity benefit payout
in the form of a monthly payment.  (iv)          Amount,
timing, and source of monthly survivor annuity benefit payout.  A surviving spouse entitled to monthly
supplemental survivor annuity benefits will receive a monthly payment equal to
the amount determined under (ii) above. 
Such payments shall commence effective with the first day of the month
following the month of the participants death.  If such surviving spouse receives (or would have received but for
the Internal Revenue Code Limitations) cost of living adjustment(s) under the
Pension Plan, the monthly payments hereunder will be automatically increased
based on the percentage of, and at the same time as, such adjustment(s).  Monthly payments hereunder shall permanently
cease upon the death of the surviving spouse, effective with the monthly
payment for the month following the month of the surviving spouses death.  Monthly payments hereunder shall be made in
accordance with the provisions of the Rabbi Trust and, to the extent not paid
under the terms of the Rabbi Trust, from general corporate assets.  (v)           Amount,
timing, and source of lump sum survivor benefit payout. A
surviving spouse entitled to a lump sum supplemental survivor benefit will
receive a lump sum payment.  This lump
sum payment will be calculated by a certified actuary and will be equal to the
present value of an immediate annuity. Such lump sum payment shall be made
within 60 days after the participants death. 
The lump sum payment shall be made in accordance with the provisions of
the Rabbi Trust and, to the extent not paid under the terms of the Rabbi Trust,
from general corporate assets.  A
surviving spouse who receives a lump sum payment shall not  15 
   be entitled to any cost of
living or other pension payment adjustments.  (vi)          Death
of surviving spouse entitled to lump sum payout.  In the event of the death of a surviving
spouse before the spouse receives the lump sum payment under section 6(a)(v) no
payment shall be made.  7.             Miscellaneous. 
None of the benefits provided under this Plan shall be subject to
alienation or assignment by any participant or beneficiary nor shall any of
them be subject to attachment or garnishment or other legal process except (i)
to the extent specially mandated and directed by applicable State or Federal
statute; or (ii) as requested by the participant or beneficiary to satisfy
income tax withholding or liability.  This Plan may be amended
from time to time, or suspended or terminated at any time, provided, however,
that no amendment or termination shall reduce any previously accrued
supplemental pension benefit under this Plan or impair the rights of any
participant or beneficiary entitled to receive current or future payment
hereunder at the time of such action. 
All amendments to this Plan may be made at the written direction of the
Committee. Notwithstanding anything else in this Plan to the contrary, the
Constellation Energy Group Board of Directors may authorize a Participant to be
eligible for benefits or may increase benefit payments.  Participation in this Plan
shall not constitute a contract of employment between Constellation Energy
Group or any of its subsidiaries and any person and shall not be deemed to be
consideration for, or a condition of, continued employment of any person.  The Plan, notwithstanding
the creation of the Rabbi Trust, is intended to be unfounded for purposes of
Title I of the Employee Retirement Income Security Act of 1974. Constellation
Energy Group shall make contributions to the Rabbi Trust in accordance with the
terms of the Rabbi Trust.  Any funds
which may be invested and any assets which may be held to provide benefits
under this Plan shall continue for all purposes to be a part of the general
funds and assets of Constellation Energy Group and no person other than
Constellation Energy Group shall by virtue of the provisions of this Plan have
any interest in such funds and assets. 
To the extent that any person acquires a right to receive  16 
   payments from Constellation
Energy Group under this Plan, such rights shall be no greater than the right of
any unsecured general creditor of Constellation Energy Group.  In the event Constellation
Energy Group becomes a party to a merger, consolidation, sale of substantially
all of its assets or any other corporate reorganization in which Constellation
Energy Group will not be the surviving corporation or in which the holders of
the common stock of Constellation Energy Group will receive securities of
another corporation (in any such case, the New Company), then the New Company
shall assume the rights and obligations of Constellation Energy Group under
this Plan.  This Plan shall be governed

   Amendments to the Constellation Energy Group, Inc. Supplemental Pension Plan (Plan)  1.             Notwithstanding anything in Section
5(b)(iii) of the Plan to the contrary, any participant who terminates
employment in connection with the management restructuring announced late in
2001, and who wants to receive a lump sum payout of his/her Plan benefit in
2002, must irrevocably elect by December 31, 2001 to rollover the present value
of his/her accrued benefit under the Plan to the Nonqualified Deferred Compensation
Plan effective December 31, 2001.  Any
additional benefit accruals under the Plan during 2002 and prior to employment
termination will automatically be paid in a lump sum from the Plan within 60
days after employment termination. 2.             Notwithstanding anything in Section 5(b)(ii) to the
contrary, participants designated by the Plan Administrator who are at least
age 55 with 10 or more years of service as of January 31, 2002 and who make an
irrevocable election in the time and manner established by the Plan
Administrator to voluntarily retire on February 1, 2002 (or such later date on
or before July 1, 2002 as required in the sole discretion of management), is
entitled to an enhanced early retirement benefit conditioned on such
participants execution of a waiver releasing Constellation Energy Group, Inc.
and its affiliates from certain claims. 
The enhanced benefit is expressed as a lump sum amount equal to three
weeks of pay (using Average Annual Base Salary and Average Incentive Award) per
year of Credited Service (as defined under the Pension Plan).  Participants who receive such enhanced
benefits are not eligible for benefits under any severance plan or arrangement.  18
