TALKING POINTS: 

o PSEG's major objective is to increase the value of our company by ensuring
  consistent profitability and growth while at the same time maintaining the
  very high standards of service and reliability we provide our customers.

o Right now, the primary question on your mind may be what effect, if any, the
  merger might have on you and your job. For the next year, the answer is,
  "probably not much".

o But whenever two companies come together, they look for savings in certain
  costs. These reductions will come from both companies and we'll work to
  minimize the effects on our workforce through careful planning, attrition,
  retirements and separation plans.

o For represented employees, aside from what may result from our current labor
  negotiations, little will change. If there are any changes in the future, they
  will occur as a result of the collective bargaining process.

o All union contracts will be honored.

o For some, the merger will produce opportunities for new jobs, growth and
  development as part of a much larger organization.

NEXT STEPS: 

o As you might imagine, there's a lot that needs to be accomplished during the
  next year. Seven regulatory agencies as well as each company's shareholders
  must approve the merger. We expect the merger to close within 12-15 months.

o A transition team made up of employees from both companies will be established
  to work through all the details.

o During this time, each company will continue to work independently, serving
  customers in its respective operating territory.

o That's where we need your help. We have to maintain our focus on our
  day-to-day work, even though there will be a tendency for us to get distracted
  by all the merger activity and perhaps rumors of staff reductions, cost
  cutting, etc.

o Frequent communications will be more important than ever. I will do my best to
  keep you informed about major developments every step of the way. You'll have
  to help us by letting us know what is on your mind and what information you
  need.

o At this point, I know you probably have lots of questions about what the
  merger means to you and the work you do. While we've thought through some of
  the answers, it will take time to develop others. All of you should have
  received a copy of the SPECIAL EDITION of PSEG OUTLOOK. It contains a lot of
  information about the announcement -- including answers to some initial
  questions. Please take the time to read it.

o Other information sources include the company's website, www.pseg.com and
  InfoCentral.

o If you have a specific question or comment, you can leave a message on PSEG's
  employee hotline -- 1 800 218-PSEG (7734). Corporate Communications will
  compile the most commonly asked questions and communicate the answers to all
  employees.

o I also encourage you to reach out to me or to your immediate supervisor with
  any questions you may have. We'll make every effort to get the answers back to
  you as quickly as possible.
