       dollar  limitation set forth in Internal Revenue Code Section  401(a)(17)
       (as adjusted by the  Commissioner  for increases in the cost of living in

       deferrals shall be in 1% multiples, subject to adjustment as necessary to
       provide for any required  withholding  taxes. Such election shall be made
       by  notification  in  the  form  and  manner   established  by  the  Plan
       Administrator  from  time to  time,  and  shall  be  effective  as of the
       beginning of the month  following  the month during which the election is
       received  by the Plan  Administrator.  Such  election  may be  revoked by
       notification in the form and manner established by the Plan Administrator
       from time to time,  and shall be  effective  as of the  beginning  of the
       month  following the month during which the revocation is received by the
       Plan Administrator.

6.     Incentive  Award  Deferral  Election.  A  participant  may elect to defer
       Incentive Award  compensation  in 1% multiples,  subject to adjustment as
       necessary to provide for any required  withholding  taxes.  Such election
       shall be made annually by notification in the form and manner established
       by the Plan  Administrator  from time to time. Such annual election shall
       be made  prior to the  Incentive  Award  performance  year,  and shall be
       effective as of the first day of such performance  year. If a participant
       initially becomes  

                                       3


       eligible  to  participate  in the Plan  during a  performance  year,  the
       election  for such  performance  year must be made  prior to the date the
       participant  initially  becomes  eligible to participate in the Plan, and
       shall be  effective  on such  date.  Elections  under  this  Section  are
       irrevocable once effective.

7.     Matching  Contributions.  Matching  Contributions  are made by BGE to the
       Plan  in an  amount  equal  to (i) up to the  rate  of  Company  Matching
       Contributions   under  the  Employee   Savings  Plan   multiplied   by  a
       participant's monthly Basic Compensation  deferral,  less (ii) the amount
       of Company  Matching  Contributions  made to the Employee Savings Plan on
       behalf of such participant with respect to such month.

8.     Plan Accounts.  Deferred Compensation and Matching Contributions shall be
       (i) credited to participant Plan Accounts as soon as practicable; (ii) to
       the extent designated by the Plan Administrator,  held for the benefit of
       the  participant in the Rabbi Trust;  and (iii) credited with earnings at
       the T. Rowe Price Prime Reserve Fund rate.  However,  a  participant  may
       elect (by  notification  in the form and manner  established  by the Plan
       Administrator from time to time) to have all or a portion of his/her Plan
       Accounts  credited  with  earnings  at a rate  equal to the T. Rowe Price
       Prime  Reserve Fund rate,  the T. Rowe Price New Income Fund rate, or one
       or more of the rates earned by  investment  options  available  under the
       Employee  Savings  Plan,  except the Common  Stock Fund and the  Interest
       Income Fund. Earnings are credited to Plan Accounts commencing on the day
       the Deferred Compensation and Matching  Contributions are credited to the
       Plan  Accounts.  Plan Accounts will be valued daily in the same manner as
       for Investment Funds under the Employee Savings Plan.

       A  participant  may  elect to  change  the  investment  option  of future
       Deferred Compensation and Matching Contributions, which election shall be
       effective  when  the  next  Deferred  Compensation  Contributions  and/or
       Matching  Contributions are credited to the participant's Plan Account. A
       participant may elect to reallocate to other  investment  options current
       Plan Accounts, which election shall be effective at the same time as, and
       valued in accordance  with, the interfund  transfer  provisions under the
       Employee  Savings Plan.  

                                       4


       Such  elections  shall be made by  notification  in the  form and  manner
       established by the Plan Administrator from time to time.

9.     Distributions  of Plan Accounts.  Distributions of Plan Accounts shall be
       made  in  cash  only,   and  to  the  extent   designated   by  the  Plan
       Administrator, from the Rabbi Trust.

       Prior to the end of the calendar year of a participant's Termination From
       Employment  with  BGE,  such   participant   must  elect  the  timing  of
       distributions  of his/her Plan Accounts.  The  participant  may elect (by
       notification in the form and manner established by the Plan Administrator
       from  time to time)  to  begin  distributions  (i) in the  calendar  year
       following  the  calendar  year  of  the  participant's  Termination  From
       Employment  with  BGE,  (ii) in the  year  following  the year in which a
       participant  attains age 70-1/2,  if later,  or (iii) any  calendar  year
       between (i) and (ii). A  participant  may elect (by  notification  in the
       form and manner  established by the Plan Administrator from time to time)
       to receive  distributions  in a single payment or in annual  installments
       during a period not to exceed  fifteen  years.  The single payment or the
       first installment payment, whichever is applicable,  shall be made within
       the first sixty (60) days of the calendar year elected for  distribution.
       Subsequent  installments,  if any,  shall be made  within the first sixty
       (60) days of each succeeding  calendar year until the participant's  Plan
       Accounts  have been paid.  In the event no  election is made prior to the
       end of the year of a participant's  Termination From Employment with BGE,
       a participant shall receive a distribution in a single payment within the
       first sixty (60) days of the  following  year.  Earnings  are credited to
       Plan  Accounts  through the date of  distribution,  and amounts  held for
       installment  payments  shall  continue to be credited with  earnings,  as
       specified in Section 8.

       If a participant dies, the entire unpaid balance of his/her Plan Accounts
       shall  be paid to the  beneficiary  or  beneficiaries  designated  by the
       participant  by  notification  in the form and manner  established by the
       Plan  Administrator  from time to time or, if no designation was made, to
       the estate of the  participant.  Payment  shall be made within sixty (60)
       days after notice of death is received by the Plan Administrator.  

                                       5


       In the event a  participant's  deferred  Incentive  Award is subsequently
       credited to the Plan, such Incentive  Award shall be paid  immediately to
       such beneficiary or beneficiaries.

       Notwithstanding  anything herein contained to the contrary, the Committee
       shall have the right in its sole discretion to vary the manner and timing
       of distributions,  and may make such distributions in a single payment or
       over  a  shorter  or  longer  period  of  time  than  that  elected  by a
       participant.

10.    Beneficiaries.  A  participant  shall  have  the  right  to  designate  a
       beneficiary or beneficiaries  who are to receive a distribution  pursuant
       to  Section  9 in  the  event  of  the  death  of  the  participant.  Any
       designation,  change  or  recision  of the  designation  shall be made by
       notification in the form and manner established by the Plan Administrator
       from time to time. The last  designation  of beneficiary  received by the
       Plan  Administrator   shall  be  controlling  over  any  testamentary  or
       purported  disposition by the participant,  provided that no designation,
       recision or change thereof shall be effective unless received by the Plan
       Administrator prior to the death of the participant.

       If  the  designated  beneficiary  is  the  estate,  or  the  executor  or
       administrator of the estate, of the participant,  a distribution pursuant
       to Section 9 may be made to the  person(s) or entity  (including a trust)
       entitled  thereto  under the will of the  participant  or, in the case of
       intestacy, under the laws relating to intestacy.

       Beneficiaries  shall  have no right to make any  investment  election  or
       change in  investment  election  pursuant to Section 8 with  respect to a
       participant's Plan Accounts.

11.    Valuation of Interest.  The Plan Administrator shall cause the value of a
       participant's Plan Accounts, at least once per year as of December 31, to
       be  determined  separately  and be reported  to BGE and the  participant.
       Valuation  of a  participant's  Plan  Accounts  shall  be  determined  in
       accordance with the procedures contained in the Employee Savings Plan.

                                       6


12.    Withdrawals.  No  withdrawals  of Plan  Accounts  may be  made,  except a
       participant  may at any time request a hardship  withdrawal  from his/her
       Plan  Accounts if he/she has  incurred  an  unforeseeable  emergency.  An
       unforeseeable  emergency is defined as severe  financial  hardship to the
       participant resulting from a sudden and unexpected illness or accident of
       the participant  (or of his/her  dependents),  loss of the  participant's
       property   due  to  casualty,   or  other   similar   extraordinary   and
       unforeseeable  circumstances  arising  as a result of events  beyond  the
       control  of the  participant.  The need to send a child to college or the
       desire  to  purchase  a  home  are  not  considered  to be  unforeseeable
       emergencies.  The  circumstance  that will  constitute  an  unforeseeable
       emergency will depend upon the facts of each case.

       A hardship withdrawal will be permitted by the Plan Administrator only as
       necessary to satisfy an immediate  and heavy  financial  need. A hardship
       withdrawal  may be permitted only to the extent  reasonably  necessary to
       satisfy the  financial  need.  Payment may not be made to the extent that
       such  hardship  is or  may  be  relieved  (i)  through  reimbursement  or
       compensation  by  insurance  or  otherwise,  (ii) by  liquidation  of the
       participant's  assets, to the extent the liquidation of such assets would
       not itself  cause  severe  financial  hardship,  or (iii) by cessation of
       deferrals under the Plan.

       The request for hardship  withdrawal shall be made by notification in the
       form and manner  established by the Plan Administrator from time to time.
       Such hardship withdrawal will be permitted only with approval of the Plan
       Administrator.  The participant will receive a lump sum payment after the
       Plan  Administrator  has had reasonable time to consider and then approve
       the request.

13.    Miscellaneous.  A  participant's  Plan  Accounts  shall not 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;  and (ii) as requested by the  participant  or
       beneficiary to satisfy income tax withholding or liability.

                                       7


       This Plan may be amended from time to time or suspended or  terminated at
       any time.  All  amendments to this Plan which would  increase or decrease
       the compensation of any senior management officer or key employee of BGE,
       either  directly  or  indirectly,  must  be  approved  by  the  Board  of
       Directors.  All other  permissible  amendments may be made at the written
       direction of the  Committee.  No amendment to or termination of this Plan
       shall prejudice the rights of any participant or beneficiary  entitled to
       receive payment hereunder at the time of such action.

       Participation  in this Plan shall not constitute a contract of employment
       between  BGE 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 unfunded  for purposes of Title I of the  Employee  Retirement  Income
       Security Act of 1974. BGE 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 BGE and no person  other  than BGE 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  payments from BGE
       under this Plan,  such rights  shall be no greater  than the right of any
       unsecured general creditor of BGE.

       This Plan shall be governed in all respects by Maryland law.
