                                                 (Commission File No. 001-09120)



1. How will staffing at various levels throughout the company be determined?

Several transition teams will be evaluating staffing levels required for the
combined companies. We are committed to communicating with employees about these
changes as decisions are made and managing this process in a sensitive and fair

2. In general, why is the merger of Exelon and PSEG good for employees?

The combination of our two firms will create the nation's largest utility. This
scale will provide new growth and developmental opportunities previously
unavailable to employees. The new company will have enhanced financial stability
and the combined company will be a significant competitive force in the

3. What will the combined company look like?

Both companies have similar operations and so the various functions would be
merged into one. Exelon Electric & Gas will emerge as the corporate parent and
assume the Exelon ticker on the NYSE. PSEG's parent company and parent name,
when merged into Exelon Electric & Gas upon closing, would be eliminated as
would its listing on the NYSE. The subsidiary operating companies of Exelon and
PSEG will retain their current names.

4. Why is the name changing? When will the new name take effect?

The new name Exelon Electric & Gas better reflects both the joint contribution
to our future business by both companies and the actual balance of the combined
energy portfolio. The regulated utilities -- PSE&G, ComEd and PECO -- will
retain their current names. The new name would become effective upon closing of
the transaction.

5. How will the merger impact 2005 labor contract negotiations?

Contract negotiations will proceed as usual and we fully expect to come to an
agreement with our unions within the next several months.

6. Why didn't you tell us about this sooner?

Because Exelon and PSEG are public companies, negotiations of this kind must be
kept confidential to prevent speculation in their stock price. We announced the
merger as soon as we could after approval by the Boards of Directors and we will
continue to keep you informed as we move forward toward closing.

7. Is this transaction a merger of equals, an acquisition by Exelon or what?

Although for financial accounting purposes it will be treated as an acquisition
by Exelon, it truly is a collaborative undertaking. The transaction has elements
of a merger of equals and an acquisition. The exchange ratio in the merger
reflects a reasonable

premium that allows shareholders of both companies to share in the synergies
made possible by the combination of the two companies. When the merger is
effective, former shareholders of PSEG will represent about 32% of the
shareholders of the merged company, and former directors of PSEG will hold
one-third of the seats on the merged company's board of directors.

8. In general, how does the merger affect electric and gas customers?

The delivery companies, including PSE&G, are expected to continue as the local
service providers. Customers ultimately should see more efficient processes for
customer care (call center, meter reading, billing, collections), new business
and reliability performance as a result of a merged company that will leverage
best practices.
