I. PURPOSE

The
purposes of this Plan are to foster attainment of the financial and operating
objectives of the Company and its Participating Affiliates, which are important
to customers and stockholders by providing incentive to certain key officers

significant impact on the growth and success of the Company and its
Participating Affiliates, thus affording to them a means of participating in
that success and an incentive to contribute further to that success. This Plan
also serves to supplement the Companys and Participating Affiliates salary
and benefit programs so as to provide overall compensation for such

 shall deem appropriate.

VI. PERFORMANCE
GOALS

For
each Plan Year, within 90 days of the beginning of the Plan Year (or, for
Participants joining the Plan during a Plan year, within 90 days of participation),
the CEO shall approve performance goals for each Participant which shall be
performance measures or objectives, whether quantitative or qualitative, which
must be achieved in order to earn an Award under this Plan. The CEO shall
approve the specific targets for any such selected performance goals. These
targets may be set at a specific level or may be expressed as relative to the
comparable measure at comparison companies or to a defined index. Such
performance goals shall include a corporate goal or goals related to the
performance of the Company and may include (i) an employer goal or goals
related to the performance of a Subsidiary or organizational business unit and
(ii) an individual goal or goals related to the individual performance of the Participant
in his/her position.

The
CEO shall determine the substance and weighting of each goal of a subsidiary
president. The CEO may determine the substance and weighting of each of the
goals of other

7

Participants or may delegate the determination of the
substance and weighting of these goals to the Subsidiary presidents with their
respective business units and direct reports.

Notwithstanding
the foregoing, however, for any Plan Year, the Committee or the CEO may, as
deemed to be appropriate, elect to adjust the applicable weightings of the
corporate goal(s), the employer goal(s) and the individual goal(s) as part of
the criteria for determining Awards for any Participant or group of
Participants in this Plan.

 each Participants Target Incentive Amount shall then be multiplied by the
 Employer Factor and the Individual Performance Factor, as appropriate, added
 together. The result of those calculations shall be then multiplied by the
 Corporate Factor to determine the Participants Incentive Award. For example,
 assume (i) a Target Incentive Amount of 50.0%, (ii) a Corporate Factor of
 0.95, (iii) an employer goal weighting of 70%, (iv) an Employer Factor of
 1.20, (v) an individual Goal weighting of 30% and (vi) an Individual
 Performance Factor of 0.80:

 however, that any Participant who has received a benefit under the Key
 Employee Severance Plan of Public Service Enterprise Group Incorporated shall
 not be entitled to a prorated payment provided for under this subsection.

 under this Plan shall be made to the Participants estate. Such payment shall

X. LIMITATIONS

Neither
the action of the Company in establishing the Plan, nor any action taken by it
or by the Committee under the provisions hereof, nor any provision of the Plan,
shall be construed as giving to any Employee the right to be retained in the
employ of the Company, its Subsidiaries or its Affiliates.

The
Company may offset against any payments to be made to a Participant or his/her
beneficiary under this Plan any amounts owing to the Company, its Subsidiaries
or its Affiliates from the Participant for any reason.

The
invalidity or unenforceability of any provision of this Plan shall in no way
affect the validity or enforceability of any other provision hereof.

XI. LIMITATION

Every
asserted right of action by or on behalf of the Company or by or on behalf of
the stockholder against any past, present or future member of the Committee or
director, officer or Employee of the Company or any Subsidiary or Affiliate
thereof, arising out of or in connection

such right of action may arise or be asserted and irrespective of the place of
residence of any such member director, officer or Employee, cease and be barred
upon the expiration of three years (i) from the date of the alleged act or
omission in respect of which such right of action arises or (ii) from the date
upon which the Companys Annual Report to Stockholders setting forth the
aggregate amount of the awards to all or any part of which such action may
relate is made generally available to stockholders, whichever date is earlier;
and every asserted right of action by or on behalf of any Employee, past,
present or future, or any beneficiary, spouse, child or legal representative
thereof, against the Company or any Subsidiary or Affiliate thereof, arising
out of or in connection with this Plan, shall, irrespective of the place where
