                                  Introduction



   KeySpan Energy Delivery ("Company" or "KeySpan")  recognizes that the success
   and  achievement  of corporate  goals is directly  related to the ability and
   performance of its employees.  In this regard, the Company has established an
   Annual  Incentive  Compensation  and Gainsharing Plan ("Plan") which provides
   incentives  for  achieving  specific   performance   objectives  and  related
   financial and operating goals.

   In the  deregulated  utility  environment,  the  need  and  use of  incentive
   compensation  is  a  logical  progression  to  providing   competitive  total
   compensation in the external marketplace.  The use of a combined base pay and
   incentive   compensation   philosophy   has   become   the  norm  in   salary
   administration programs.

   In managing the compensation  programs at KeySpan, it is recognized that both
   base pay and  incentives  are  integral  components  in an  effective  salary
   program. One of our compensation  objectives is to identify methods which can
   be  used  to  enhance  our  existing  programs  to  create  better  "pay  for
   performance"  plans. In this regard,  the Plan provides a method to establish
   specific performance goals. The Plan also provides a direct link between team
   and group performance results and corporate initiatives.  The key operational
   goals are based upon the corporate  initiatives and  specifically  focus upon
   growth, competitive pricing, customer satisfaction and employee excellence.

e) Provide a  compensation  environment  which fosters the retention of talented

2.    Administration
      --------------

   All  determinations  in  connection  with the Plan  with  regard  to  officer
   compensation  shall be made by the Board of  Directors  after  receiving  the
   recommendations  of its respective  Compensation  and  Nominating  Committee,
   herein called the "Committee". Such determinations shall be final, conclusive
   and binding.
   The Plan will be administered by the Chief Executive Officer and
   the Senior Vice President over Human Resources,  under the general  direction
   of the Committee.  The Compensation Department and Strategic Planning will be
   responsible for the Plan design recommendations and administration.
   The Committee will approve performance goals for the plan year as well as the
   potential threshold, target and maximum award percentages that will provide a
   reasonable and competitive level of awards if the primary threshold goals are
   achieved.

   The Committee  shall have full and final authority to designate the incentive
   award for each  participant,  and to determine  the  performance  objectives,
   amount and form of all  incentive  awards.  The  Committee  may delegate such
   responsibilities, other than final approval of awards, to the Chief Executive
   Officer who may then delegate such responsibility to any other officer of the
   Company.

   The  Committee,  as soon as  practicable  following the end of the plan year,
   will review for approval the recommended  incentive  awards to be provided to
   the Plan  participants  for the previous year.  The Board of Directors  shall
   make the final  determination  regarding  approval of all  awards.  Incentive
   awards for all  participants,  except  the Chief  Executive  Officer  will be
   recommended  by the Chief  Executive  Officer  subject to the approval of the
   Committee  and the  Board of  Directors.  The  incentive  award for the Chief
   Executive  Officer  will be  recommended  by the  Chairman  of the  Committee
   subject to the approval of the Board of Directors.

   The  Committee  shall,  in  their  sole  discretion,  recommend  whether  any
   participant  shall be eligible to earn an  incentive  award.  In the event of
   extraordinary  windfall  profits or losses beyond the control of the Company,
   or in  circumstances  where  prudent  management  decisions  will diminish or
   preclude  the  payment  of  incentive  awards,  the  Committee  will have the
   discretion to recommend to the Board to provide or eliminate incentive awards
   as deemed necessary. The Committee can also award such amounts that they deem
   appropriate to recognize superior results which have been achieved.  Finally,
   the  Committee  may recommend to the Board of Directors to amend or terminate
   the Plan at with or without notice to the participants.

         Directors.  The amounts  required by law to be withheld  for income and

         of the  401(k)  plan,  will be  deducted  from the award  payments.  An
         employee  must be actively  employed as of the date the awards are paid
         to receive an award.


      7. Change of Employment Status During the Plan Year

         a)   Promotions/Demotions

         Awards to each plan participant will be based on the employee's  target
         in effect as of December 1st of the plan year,  and status in effect at
         the end of the plan year.  Employees who are demoted due to performance
         during the plan year,  shall be eligible  for an award at the target of
         their new position.

         b)   Termination

         An employee  whose  services  are  terminated  during the plan year for
         reasons of misconduct, failure to perform, or other performance related
         reasons  shall  not be  considered  for an award.  Unless  the Board of
         Directors shall otherwise  determine,  such an individual  shall not be
         entitled to any portion of an incentive  award.  If the  termination is
         due to other reasons such as  reorganization,  transfer to  subsidiary,
         etc., and the  termination  is not due to a fault of the employee,  the
         employee may be considered for a pro-rata award.

         c)   Resignation

         An  employee  who  resigns to accept  employment  elsewhere  (including
         self-employment)  during  the plan year or prior to the date the awards
         are paid will not be considered for an award.

          d)   Death,  Disability,  Retirement,  Leave of Absence (for Sickness,
               FMLA or Personal Reasons)

         An employee  whose status as an active  employee is changed  during the
         plan year for any of the reasons cited may be considered for a pro-rata
         award at the end of the plan year  depending  upon the actual length of
         paid service during the plan year. In the event of death,  any prorated
         payment shall be made to the beneficiary.

     8.  Change In Control
         -----------------

     In the  event of a change in  control,  all  participants  shall be paid an
     award based upon the  effective  date of the change in  control.  The award
     would either be prorated or annualized  based upon the timing of the change
     of control. Prorated awards will be made as determined by the Committee.

         "Incumbent  Board")  cease  for any  reason  to  constitute  at least a
         majority of the Board; provided,  however, that any individual becoming
         a  Director  subsequent  to the date of this Plan  whose  election,  or
         nomination for election by the Company's shareholders,  was approved by
         a vote of at least a majority  of the  Directors  then  comprising  the

         Combination; or

         Retirement  Plan  year in which  the  recipient  was  employed,  if the
         employee  was a  participant  in an  existing  incentive  plan prior to
         10/1/95.  Cash payments of the portions that were actually  deferred or
         would have normally been deferred or any nondeferred portions which are
         received after retirement or death will not be considered  compensation
         for Retirement Plan benefit purposes.

          c)   No  benefit  under  the plan  shall in any  manner  or  extent be
               assigned,  alienated, or transferred by any participant under the
               Plan,  or be subject to  attachment,  garnishment  or other legal
               process.

         d)   Except as addressed herein,  incentive  compensation payments will
              not affect the level of benefits under any other employee  benefit
              plan or program of the Company.

         e)   Cash  payments  will be eligible  for any  Employee  Savings  Plan
              401(k)  deferral or after tax  contribution  election  made by the
              employee  subject to the  limitations  established  in the current
              401(k) plan.

         f)   The  Board of  Directors  of the  Company  may  change,  modify or
              terminate  the Plan in whole or in part,  either in  general or in
              particular cases, at any time with or without notice.
