                                    between
                        Constellation Energy Group, Inc.
                                      and
                          T. Rowe Price Trust Company




         This  Agreement  made  this  30th day of April,  1999,  by and  between
Constellation  Energy  Group,  Inc., a Maryland  Corporation,  or its  successor
("CEG") and T. Rowe Price Trust Company ("Trustee");


                                WITNESSETH THAT:

         WHEREAS,  effective with the April 30, 1999 share exchange  between CEG
and the common  stockholders of Baltimore Gas and Electric Company ("BGE"),  BGE
transferred to CEG the former BGE Nonqualified  Deferred  Compensation  Plan and
BGE's rights and obligations  under the Grantor Trust Agreement dated as of June
1, 1996, between BGE and T. Rowe Price Trust Company.

         WHEREAS,   CEG  has  adopted  the  Constellation   Energy  Group,  Inc.
Nonqualified Deferred Compensation Plan (formerly the Baltimore Gas and Electric
Company Nonqualified Deferred Compensation Plan) ("Plan");

         WHEREAS, CEG has incurred or expects to incur liability under the terms
of such Plan with respect to the individuals participating in such Plan;

         WHEREAS, CEG wishes to establish a trust ("Trust") and to contribute to
the Trust  assets  that  shall be held  therein,  subject to the claims of CEG's
creditors in the event of CEG's  Insolvency,  as defined in Section 3(a) hereof,
until paid to Plan  participants  and their  beneficiaries in such manner and at
such times as specified in the Plan;

         WHEREAS,  it is the  intention  of the  parties  that this Trust  shall
constitute an unfunded  arrangement  and shall not affect the status of the Plan
as  an  unfunded  plan   maintained  for  the  purpose  of  providing   deferred
compensation  for a select group of management or highly  compensated  employees
for purposes of Title I of the Employee Retirement Income Security Act of 1974;

                                       1


         WHEREAS,  it is the intention of CEG to make contributions to the Trust
to  provide a source of funds to assist  it in the  meeting  of its  liabilities
under the Plan; and

         NOW,  THEREFORE,  the parties do hereby  establish  the Trust and agree
that the Trust shall be comprised, held and disposed of as follows:


         Section 1.        Establishment of Trust.

         (a) CEG hereby adopts and establishes with Trustee the Trust consisting
of such sums of cash (the "principal")  that currently  constitute the Trust and
as from time to time  shall be paid to  Trustee  to be held,  administered,  and
disposed of by Trustee as provided in this Trust Agreement. The principal of the
Trust and any earnings thereon (the "Trust Assets") shall be held by Trustee and
shall be dealt with in accordance  with the  provisions of this Trust  Agreement
until all payments required by this Trust Agreement have been made.

         (b) The Trust hereby established shall be irrevocable.

         (c) The Trust is  intended to be a grantor  trust,  of which CEG is the
grantor,  within the  meaning of subpart  E, part I,  subchapter  J,  chapter 1,
subtitle  A of the  Internal  Revenue  Code of 1986,  as  amended,  and shall be
construed accordingly.

         (d) The Trust Assets shall be held  separate and apart from other funds
of CEG and  shall  be  used  exclusively  for  the  uses  and  purposes  of Plan
participants and general  creditors as herein set forth.  Plan  participants and
their  beneficiaries  shall  have  no  preferred  claim  on,  or any  beneficial
ownership  interest in, any Trust Assets.  Any rights created under the Plan and
this  Trust  Agreement  shall  be  mere  unsecured  contractual  rights  of Plan
participants  and their  beneficiaries  against  CEG.  Any Trust  Assets will be
subject to the claims of CEG's general  creditors under federal and state law in
the event of Insolvency, as defined in Section 3(a) herein.

         (e) As soon as  practicable,  but no later than the last  business day,
which for purposes of this Trust  Agreement  shall be defined as any day the New
York  Stock  Exchange  is open  for  business  ("Business  Day"),  of the  month
following  the month in which a payment  of  compensation  subject to a deferral
election under the Plan would otherwise have been paid, CEG shall be required to
irrevocably  contribute  cash to the Trust in an amount  equal to such  Deferred
Compensation, plus any Matching Contributions related thereto, to the extent the
Plan  requires  such  funding.  Trustee  shall have no  obligation to compute or
compel such contribution(s).

         (f) The Board of Directors of CEG may at any time by  resolution  amend
the  contribution  requirements of Section 1(e) hereof such that CEG will not be
required  to make  additional  contributions  of cash  to the  Trust  or will be
required  to  make  only a  stated  percentage  of the  contributions  otherwise
required under Section 1(e) hereof. If Section 1(e) is so amended, contributions
of cash to the Trust over and above the amounts required under Section 1(e) if


                                       2


amended,  will be in the sole discretion of CEG pursuant to Section 1(g) hereof.
Trustee shall have no obligation to compute or compel such contribution(s).

         (g) CEG, in its sole discretion,  may at any time or from time to time,
make  additional  deposits  of cash in trust with  Trustee to augment  the Trust
Assets to be held,  administered  and disposed of by Trustee as provided in this
Trust Agreement.  Neither Trustee nor any Plan participant or beneficiary  shall
have any right or obligation to compel such additional deposits.

         Section 2.       Payments to Plan Participants and Their Beneficiaries.

         (a) CEG shall  deliver or cause to be  delivered  to Trustee a schedule
(the "Payment  Schedule")  that indicates the amounts payable in respect of each
Plan participant (or his or her beneficiaries), that provides a formula or other
instructions  acceptable to Trustee for determining the amounts so payable,  the
form in which such amount is to be paid (as provided for or available  under the
Plan),  and the time of  commencement  for  payment of such  amounts.  Except as
otherwise provided herein,  Trustee shall make payments to the Plan participants
and  their  beneficiaries  in  accordance  with  such  Payment  Schedule.  If so
instructed by CEG, the Trustee shall withhold  federal and state taxes from each
payment under this  agreement at the rate(s)  designated by CEG and shall report
and pay such amounts to the appropriate federal and state taxing authorities.

         (b) The entitlement of a Plan  participant or his or her  beneficiaries
to benefits  under the Plan shall be determined by CEG or such party as it shall
designate under the Plan and any claim for such benefits shall be considered and
reviewed under the  procedures set out in the Plan.  Trustee shall have no right
or duty to inquire into CEG's decisions with respect to entitlement to benefits.

         (c) CEG may make payment of benefits  directly to Plan  participants or
their  beneficiaries  as they become due under the terms of the Plan.  CEG shall
notify  Trustee in writing of its decision to make payment of benefits  directly
prior to the time amounts are payable to  participants  or their  beneficiaries.
CEG shall provide to the Trustee documentation substantiating that such payments
were made under the terms of the Plan.  If such  documentation  is not provided,
Trustee  shall  make such  payments  in  accordance  with the  Payment  Schedule
directly to Plan participants and their beneficiaries. In addition, if the Trust
Assets,  are not sufficient to make such payments of benefits in accordance with
the terms of the Plan,  CEG shall make the  balance  of each such  payment as it
falls due.  Trustee  shall notify CEG where Trust Assets are not  sufficient  to
make  benefit  payments,  however,  Trustee  shall have no duty to  require  any
contributions to be made, or to determine that any of the contributions received
comply with the conditions and limitations of the Plan.

         (d) In the event  there is a final  judicial  determination  or a final
determination  by the Internal  Revenue  Service that the Plan  participants  or
their  beneficiaries  are subject to any tax with  respect to any  amounts  held
under the terms of the Trust,  then Trustee solely at the direction of CEG shall
make payments from the Trust to such Plan participants or their beneficiaries in
such amounts as set forth in such final  determination for the purpose of paying
all applicable


                                       3


taxes and interest and any  penalties  thereon which such Plan  participants  or
their beneficiaries  incur arising out of such determination.  CEG's decision as
to whether a final determination has occurred shall be binding and conclusive on
all Plan participants and their beneficiaries.

         Section 3.        Trustee Responsibility Regarding Payments to Trust
                           Beneficiary When CEG is Insolvent.

         (a) Upon  receipt of  notification  issued in  accordance  with Section
3(b)(1) hereof, Trustee shall cease payment of benefits to Plan participants and
their beneficiaries if CEG is Insolvent. CEG shall be considered "Insolvent" for
purposes of this Trust  Agreement if (1) CEG makes a voluntary  filing under the
United States Bankruptcy Code, or (2) CEG is subject to a pending  proceeding as
a debtor under the United States Bankruptcy Code.

         (b) At all times during the  continuance of this Trust,  as provided in
Section  1(d)  hereof,  the Trust  Assets  shall be subject to claims of general
creditors of CEG under federal and state law as set forth below.

                  (1) The  Board of  Directors  of CEG and the  Chief  Executive
Officer  of CEG  shall  have the duty to  inform  Trustee  in  writing  of CEG's
Insolvency.  When so  informed  or when the Trustee is in receipt of a copy of a
bankruptcy  petition  relating  to CEG or a court  order  determining  CEG to be
Insolvent, Trustee shall discontinue payment of benefits to Plan participants or
their beneficiaries.

                  (2)  Unless  Trustee  has  received  written  notification  in
accordance  with  Section  3(b)(1) of this Trust  Agreement,  Trustee may in all
events rely on such evidence  concerning  CEG's  solvency as may be furnished by
CEG to Trustee.

                  (3) If at any time Trustee has received  written  notification
in accordance with Section 3(b)(1),  Trustee shall discontinue  payments to Plan
participants  or their  beneficiaries  and shall  hold the Trust  Assets for the
benefit of CEG's general creditors. Nothing in this Trust Agreement shall in any
way diminish any rights of Plan  participants or their  beneficiaries  to pursue
their rights as general  creditors of CEG with respect to benefits due under the
Plan or otherwise.

                  (4)  Trustee  shall  resume the  payment of  benefits  to Plan
participants or their  beneficiaries  in accordance with Section 2 of this Trust
Agreement  only after  Trustee has received a copy of a court order  determining
CEG to be no longer  Insolvent or evidencing that such bankruptcy  proceeding is
dismissed in connection  with any  notification  made in accordance with Section
3(b)(1)

         (c) Provided that there are sufficient assets, if Trustee  discontinues
the  payment of  benefits  from the Trust  pursuant  to Section  3(b) hereof and
subsequently   resumes  such   payments,   the  first  payment   following  such
discontinuance  shall include the  aggregate  amount of all payments due to Plan
participants or their  beneficiaries  under the terms of the Plan for the period
of such


                                       4


discontinuance,  less  the  aggregate  amount  of  any  payments  made  to  Plan
participants or their  beneficiaries by CEG in lieu of the payments provided for
hereunder during any period of discontinuance.

         Section 4.        Payments to CEG.

         (a) Except as provided in Section 3 and Section 4(b) hereof,  CEG shall
have no right or power to direct Trustee to return to CEG or to divert to others
any of the Trust  Assets  before all payment of benefits  have been made to Plan
participants  and their  beneficiaries  pursuant to the terms of the Plan and of
this Trust Agreement.

         (b) In the event (1) CEG makes  payment of  benefits  directly  to Plan
participants or their  beneficiaries in accordance with Section 2(c) hereof,  or
(2) if for any  other  reason  Trust  Assets  exceed  the  market  value  of the
aggregate  balances  of Plan  participant  accounts,  then  CEG may in its  sole
discretion,  direct  Trustee in writing to distribute the amount of such payment
or excess,  in whole or in part,  to CEG  provided  such  distribution  does not
contravene any provision of law.

         (c) Notwithstanding  Section 4(b)(2) hereof, CEG may not direct Trustee
to  distribute  such excess  Trust  Assets for 2 years from the date a Change of
Control is deemed to occur under  Section  13(e) hereof  except to reimburse CEG
for any payment it makes  directly to  participants  in accordance  with Section
2(c) hereof.

         Section 5.        Investment Authority.

         (a) In no event may Trustee  invest in securities  (including  stock or
rights to acquire stock) or  obligations  issued by CEG, other than a de minimis
amount held in common investment  vehicles in which Trustee invests.  All rights
associated  with  assets  of the  Trust  shall  be  exercised,  solely  upon the
direction of CEG, by Trustee or the person designated by Trustee and shall in no
event be exercisable by or rest with Plan participants and their beneficiaries.

         (b) Trustee  shall  invest and  reinvest  the Trust Assets and keep the
Trust  invested,  without  distinction  between  principal  and income,  in such
investments as directed in writing by CEG or its designee, which instruction may
be modified from time to time by CEG or its designee. Trustee shall have no duty
to question  any action or  direction  of CEG or its  designee or any failure to
give  directions,  or to  make  any  suggestion  to CEG  as to  the  investment,
reinvestment, disposition or distribution of, such assets.

         (c) CEG shall have the right, at anytime,  and from time to time in its
sole discretion, and with Trustee's approval, to substitute assets of equal fair
market value for any asset held by the Trust.

         Section 6.        Disposition of Income.

                                       5


         During the term of this Trust, all income received by the Trust, net of
expenses  and  taxes,  shall be  accumulated  and  reinvested,  until  otherwise
required for disbursement under the terms of this Trust Agreement.

         Section 7.        Accounting by Trustee.

         (a)  Trustee  shall  keep  accurate,   and  detailed   records  of  all
investments,  receipts,  disbursements and all other transactions required to be
made, including such specific records as shall be agreed upon in writing between
CEG and Trustee.  Within 60 days  following  the close of each calendar year and
within 60 days after the  removal  or  resignation  of  Trustee,  Trustee  shall
deliver to CEG a written account of its  administration of the Trust during such
year or during the period from the close of the last  preceding year to the date
of such  removal  or  resignation,  setting  forth  all  investments,  receipts,
disbursements and other transactions  effected by it, including a description of
all securities and investments  purchased and sold with the cost or net proceeds
of such  purchases or sales (accrued  interest paid or  receivables  being shown
separately),  and showing all cash,  cost and market value of all securities and
other  property  held in the  Trust at the end of such year or as of the date of
such removal or resignation, as the case may be.

         (b) CEG shall  prepare and file such tax  returns and other  reports as
may be required for the Trust, with any taxing authority or any other government
authority  except for IRS Form 1041  which  shall be  prepared  and filed by the
Trustee.

         Section 8.        Responsibility of Trustee.

         (a) Trustee  shall act with the care,  skill,  prudence  and  diligence
under the  circumstances  then  prevailing  that a prudent person acting in like
capacity  and  familiar  with  such  matters  would  use  in the  conduct  of an
enterprise  of a like  character  and with like aims,  provided,  however,  that
Trustee shall incur no liability, costs or expense to any person, for any action
taken  pursuant  to a  direction,  request  or  approval  given by CEG  which is
contemplated  by, and in conformity  with, the terms of this Trust Agreement and
is  given  in  writing  by CEG.  Trustee  shall  also be  reimbursed  by CEG for
reasonable  expenses  or  fees  incurred  in  connection  with  governmental  or
regulatory inquiries related to this Trust.

         (b)  If  Trustee  undertakes  or  defends  any  litigation  arising  in
connection with this Trust,  unless such  litigation  results in a determination
that Trustee  breached its duties  undertaken  pursuant to this Trust Agreement,
CEG agrees to indemnify Trustee against Trustee's reasonable costs, expenses and
liabilities  (including,  without  limitation,  reasonable  attorneys'  fees and
expenses) relating thereto and to be primarily liable for such payments.  If CEG
does not pay such costs, expenses and liabilities in a reasonably timely manner,
Trustee may obtain payment from the Trust.

         (c) Trustee may consult with legal counsel (who may also be counsel for
CEG generally)  with respect to any of its duties or obligations  hereunder.  In
the event that Trustee


                                       6


anticipates  charging  legal fees to the Trust,  Trustee must obtain CEG's prior
written  consent for such legal counsel,  which consent will not be unreasonably
withheld.

         (d)  Trustee  may  hire  agents,  accountants,   actuaries,  investment
advisors,   financial  consultants  or  other  professionals  to  assist  it  in
performing any of its duties or obligations hereunder. In the event that Trustee
anticipates  charging fees for such  services to the Trust,  Trustee must obtain
CEG's prior written  consent for such legal  counsel,  which consent will not be
unreasonably withheld.

         (e)  Notwithstanding  any powers  granted to Trustee  pursuant  to this
Trust  Agreement or to  applicable  law,  Trustee  shall not have any power that
could give this Trust the  objective  of carrying on a business and dividing the
gains therefrom,  within the meaning of section  301.7701-2 of the Procedure and
Administrative Regulations promulgated pursuant to the Internal Revenue Code.

         Section 9.        Compensation and Expenses of Trustee.

         CEG shall pay all  reasonable  administrative  and  Trustee's  fees and
expenses. If not so paid, the fees and expenses shall be paid from the Trust.

         Section 10.       Resignation and Removal of Trustee.

         (a)  Trustee  may  resign at any time by written  notice to CEG,  which
shall be effective 30 days after  receipt of such notice  unless CEG and Trustee
agree otherwise.

         (b) Except as provided in Section 10(c),  Trustee may be removed by CEG
on 30 days written notice unless CEG and Trustee agree otherwise.

         (c) Upon  written  notification  by CEG that a Change  of  Control,  as
defined in Section 13(e) hereof has occurred,  Trustee may not be removed by CEG
for 2 years from the date a Change of Control is deemed to occur  under  Section
13(e) hereof.

         (d) If Trustee  resigns  within 2 years after a Change of  Control,  as
defined  herein,  CEG shall apply to a court of competent  jurisdiction  for the
appointment of successor Trustee or for instructions.

         (e) Upon  resignation  or  removal  of  Trustee  and  appointment  of a
successor  Trustee,  all Trust Assets shall  subsequently  be transferred to the
successor  Trustee.  The transfer shall be completed at the later of (1) 30 days
after receipt of notice of resignation or removal of Trustee or (2)  appointment
of successor Trustee.

         (f) If Trustee  resigns or is removed,  a successor shall be appointed,
in accordance  with Section 11 hereof,  by the effective  date of resignation or
removal under paragraphs (a) or (b) of this


                                       7


section.  If no such appointment has been made,  Trustee may apply to a court of
competent  jurisdiction for appointment of a successor or for instructions.  All
reasonable  expenses  of  Trustee in  connection  with the  proceeding  shall be
allowed as administrative expenses of the Trust.

         Section 11.       Appointment of Successor.

         (a) If Trustee  resigns or is removed in accordance  with Section 10(a)
or (b) hereof,  CEG may appoint any third party, such as a bank trust department
or other party that may be granted  corporate trustee powers under state law, as
a successor to replace  Trustee upon  resignation  or removal.  The  appointment
shall be effective when accepted in writing by the successor Trustee,  who shall
have all of the rights and powers of the  former  Trustee,  including  ownership
rights in the Trust Assets.  The former  Trustee  shall  execute any  instrument
necessary or reasonably requested by CEG or the successor Trustee (in which case
former Trustee shall have received a copy of successor Trustee's  acceptance) to
evidence the transfer of the Trust Assets.

         (b) If Trustee  resigns  pursuant to the  provisions  of Section  10(d)
hereof,  the appointment of a successor Trustee shall be effective when accepted
in writing by the successor  Trustee.  The successor  Trustee shall have all the
rights and powers of the former  Trustee,  including  ownership  rights in Trust
Assets. The former Trustee shall execute any instrument  necessary or reasonably
requested by the successor Trustee to evidence the transfer of the Trust Assets.

         (c) The successor  Trustee need not examine the records and acts of any
prior  Trustee and may retain or dispose of existing  Trust  Assets,  subject to
Sections 7 and 8 hereof.  The successor Trustee shall not be responsible for and
CEG shall indemnify and defend the successor Trustee from any claim or liability
resulting  from any action or  inaction  of any prior  Trustee or from any other
past event, or any condition existing at the time it becomes successor Trustee.

         (d) In the event of such  removal or  resignation,  Trustee  shall duly
file with CEG a written account as provided in Section 7(a) hereof.

         Section 12.       Amendment or Termination.

         (a) Except as provided in Section  12(d),  this Trust  Agreement may be
amended by a written instrument executed by Trustee and CEG. Notwithstanding the
foregoing,  no such amendment shall conflict with the terms of the Plan or shall
make the Trust revocable.

         (b) The  Trust  shall  not  terminate  until  the  date on  which  Plan
participants and their beneficiaries are no longer entitled to benefits pursuant
to the terms of the Plan or have received  payment of all benefits to which they
are entitled under the terms of this Trust  Agreement.  Upon  termination of the
Trust any assets remaining in the Trust shall be returned to CEG.

         (c) Upon written  approval of all Plan  participants  or  beneficiaries
entitled to payment of benefits pursuant to the terms of the Plan and this Trust
Agreement, CEG may terminate this Trust


                                       8


prior to the time all benefit  payments under the Plan and this Trust  Agreement
have been made. All Trust Assets at termination shall be returned to CEG.

         (d)  This  Trust  Agreement  may  not be  amended  by CEG  for 2  years
following a Change of Control,  unless CEG  determines  that such amendment does
not adversely affect the rights of the Plan participants and their beneficiaries
entitled  to payment  of  benefits  pursuant  to terms of the Plan on the date a
Change of Control is deemed to occur.

         Section 13.       Miscellaneous.

         (a) Any  provision of this Trust  Agreement  prohibited by law shall be
ineffective  to the extent of any such  prohibition,  without  invalidating  the
remaining provisions hereof.

         (b) Benefits payable to Plan participants and their beneficiaries under
this  Trust  Agreement  may not be  anticipated,  assigned  (either at law or in
equity), alienated, pledged, encumbered or subjected to attachment, garnishment,
levy,  execution  or other  legal or  equitable  process,  and any attempt to so
alienate,  sell, transfer,  assign, pledge, attach, charge or otherwise encumber
any such amount,  whether  presently or thereafter  payable,  shall be void. The
Trust shall be in no manner liable for or subject to the debts or liabilities of
any participant.

         (c)  This  Trust  Agreement  shall  be  governed  by and  construed  in
accordance with the laws of the State of Maryland and applicable federal law.

         (d)  All  words  beginning  with  an  initial  capital  letter  and not
otherwise  defined  herein  shall have the  meaning  set forth in the Plan.  All
singular terms defined in this Trust will include the plural and vice versa.

         (e) For a Change of control to be effective  with respect to this Trust
Agreement,  CEG must issue written notification of Change of Control to Trustee.
Trustee has no obligation to make any independent  determination or verification
that a Change of Control has  occurred.  For  purposes of this Trust  Agreement,
Change of Control  shall mean (a) the  purchase  or  acquisition  by any person,
entity or group of persons  (within the meaning of section 13(d) or 14(d) of the
Securities  Exchange  Act of  1934  (the  "Exchange  Act"),  or  any  comparable
successor  provisions) of beneficial ownership (within the meaning of Rule 13d-3
promulgated  under  the  Exchange  Act) of 20  percent  or more  of  either  the
outstanding  shares of common stock of CEG or the combined voting power of CEG's
then outstanding  shares of voting securities  entitled to a vote generally,  or
(b) the  consummation of, following the approval by the stockholders of CEG of a
reorganization,  merger,  or consolidation of CEG, in each case, with respect to
which  persons  who  were   stockholders  of  CEG  immediately   prior  to  such
reorganization,  merger, or consolidation do not,  immediately  thereafter,  own
more than 50 percent of the combined  voting power entitled to vote generally in
the election of directors of the  reorganized,  merged or consolidated  entity's
then outstanding  securities,  or (c) a liquidation or dissolution of CEG or the
sale of substantially  all of its assets,  or (d) a change of more than one-half
of the members of the Board of Directors of


                                       9


CEG  within a 90-day  period  for  reasons  other  than  death,  disability,  or
retirement of such members.

         (f) CEG shall  certify  to  Trustee  the name or names of any person or
persons authorized to act for CEG under this Trust Agreement. Such certification
shall be signed by a Vice  President of CEG.  Until CEG notifies  Trustee,  in a
