         an employee may participate in the Plan to the extent set forth in such
         designation.

5.       Basic Compensation  Deferral Election.  Unless otherwise  designated in
         writing  by the Plan  Administrator,  a  participant  may  defer  Basic
         Compensation as set forth in this Section 5. A participant may elect to
         defer up to 15% of monthly Basic  Compensation.  A participant may also
         elect to defer up to 100% of Basic  Compensation,  if any, in excess of
         the  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   accordance   with   Internal   Revenue   Code  Section
         401(a)(17)(B)).  Any  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


                                       3


         performance  year.  If a  participant  initially  becomes  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.       Other  Deferral  Election.  A  participant  may elect to  defer,  in 1%
         multiples,  other forms of compensation  that are designated in writing
         by the Plan Administrator. Such election must be made prior to the date
         the compensation is earned by the  participant,  by notification in the
         form and  manner  established  by the Plan  Administrator  from time to
         time.  Such  election is effective as of the date the  compensation  is
         earned. Elections under this Section are irrevocable once effective.

8.       Matching  Contributions.  Matching Contributions are made by CEG 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.

9.       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


                                       4


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

10.      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 CEG, 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 CEG, (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 CEG, a participant shall
         receive a distribution in a


                                       5


         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 9.

         If a  participant  dies,  the entire  unpaid  balance  of his/her  Plan
         Accounts  shall  be  paid  to the  beneficiary(ies)  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,
         unless  prior  to the end of the  calendar  year  of the  participant's
         Termination  From Employment with CEG, the participant  elected (in the
         form and  manner  established  by the Plan  Administrator  from time to
         time)  a  delayed  and/or  installment  distribution  option  for  such
         beneficiary(ies); provided, however that (i) such a distribution option
         election shall be effective only if the value of the participant's Plan
         Accounts is more than $50,000 on the date of the  participant's  death;
         and (ii) the final  distribution must be made to such  beneficiary(ies)
         no later than 15 years after the participant's  death. After the end of
         the calendar year of a participant's  Termination  From Employment with
         CEG, a  distribution  option  election for a particular  beneficiary is
         irrevocable;  provided,  however,  that  the  participant  may  make  a
         distribution  option  election for a new  beneficiary  who is initially
         designated  after the  participant's  Termination  From Employment with
         CEG,  and  such  election  is  irrevocable  with  respect  to  the  new
         beneficiary.

         In the event a  participant's  deferred  Incentive Award is credited to
         the Plan after the  participant's  death, such Incentive Award shall be
         either  paid  to  his/her  beneficiary(ies),  or  if a  delayed  and/or
         installment  distribution option was elected for such beneficiary(ies),
         paid as part of the aggregate  Plan  Accounts in  accordance  with such
         election.

         Upon the death of a participant's beneficiary for whom a delayed and/or
         installment  distribution option was elected, the entire unpaid balance
         of  the   participant's   Plan   Accounts   shall   be   paid   to  the
         beneficiary(ies)


                                       6


         designated by the participant's beneficiary 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's
         beneficiary.  Payment shall be made within sixty (60) days after notice
         of death is received by the Plan Administrator.

         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.

11.      Beneficiaries.  A  participant  shall  have the  right to  designate  a
         beneficiary(ies)  who  is to  receive  a  distribution(s)  pursuant  to
         Section  10  in  the  event  of  the  death  of  the   participant.   A
         participant's  beneficiary(ies)  for whom a delayed and/or  installment
         distribution  option was  elected  shall have the right to  designate a
         beneficiary(ies)  who is to receive a distribution  pursuant to Section
         10 in the event of the death of the participant's beneficiary(ies).

         Any  designation,  change or recision of the designation of beneficiary
         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 (or,
         if applicable,  the participant's  beneficiary(ies)),  provided that no
         designation,  recision  or change  thereof  shall be  effective  unless
         received  by  the  Plan  Administrator   prior  to  the  death  of  the
         participant (or, if applicable, the participant's beneficiary(ies)).

         If the  designated  beneficiary  is the  estate,  or  the  executor  or
         administrator of the estate, of the participant (or, if applicable, the
         participant's beneficiary(ies)),  a distribution pursuant to Section 10
         may be made to the  person(s) or entity  (including  a trust)  entitled
         thereto  under the will of the  participant  (or,  if  applicable,  the
         participant's  beneficiary(ies)),  or, in the case of intestacy,  under
         the laws relating to intestacy.

                                       7


         A participant's  beneficiary(ies) for whom a delayed and/or installment
         distribution  option was elected shall have the right,  after the death
         of  the  participant,  to  make  investment  elections  or  changes  in
         investment  elections with respect to a participant's  Plan Accounts to
         the same extent  available to the participant  pursuant to Section 9. A
         beneficiary(ies)  of the participant's  beneficiary(ies)  shall have no
         right to make any investment  election or change in investment election
         pursuant to Section 9 with respect to a participant's Plan Accounts.

12.      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 CEG  and  the
         participant (or, if applicable,  the  participant's  beneficiary(ies)).
         Valuation of a  participant's  Plan  Accounts  shall be  determined  in
         accordance with the procedures contained in the Employee Savings Plan.

13.      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  financial
         emergency.  An unforeseeable  financial  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


                                       8


         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.

14.      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.

         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 CEG, 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  CEG 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. CEG 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


                                       9


         assets  of CEG and no  person  other  than CEG  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
         CEG under this Plan,  such rights shall be no greater than the right of
         any unsecured general creditor of CEG.

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