Also included in this report are the sales statistics by quarter for Energy

Item 9. Regulation FD Disclosure

As previously announced, on July 31, 2002 Exelon Corporation conducted its
Second Quarter Earnings Conference Call. Members of management participating in
the call included Chairman and CEO John W. Rowe, Senior Vice President and Chief
Financial Officer, Ruth Ann M. Gillis, CEO of Exelon Delivery, Pamela B.
Strobel, President of Enterprises, George H. Gilmore and Executive Vice
President, Ian McLean. The call was open to all on a listen-only basis and was
audio web-cast. Telephone replays will be available through August 15, 2002. The
U.S. call-in number is 877.519.4471 and the international call-in number is
973.341.3080. The confirmation code is 3391011. In addition, the call will be
archived on Exelon's web site, www.exeloncorp.com; please choose the Investor
Relations page.


During the call management reviewed issues outlined in the press release.
Management indicated that the process for preparing to certify the Exelon
financial statements filed with the SEC is nearly complete, and that the
certifications are expected to be filed at the time of the second quarter 10-Q
filing. Management indicated that wholesale market prices for energy continue to
be weaker than expected, with average around-the-clock prices for July through
December projected to be $28 per MWh in PJM and $22 per MWh in MAIN. These
average price projections are about $3 per MWh lower than previous price
projections. Management further observed that the around the clock price
projections for the summer months are about $15 per MWh lower than previous
projections and that those months are more sensitive to price changes because
the portfolio is least hedged in those months. Previously provided estimates of
a $0.03 per share sensitivity to each $1/MWh change in the average around the
clock price still holds over the course of a year, but cannot be applied to
individual months, such as July and August due to the higher than average level
of price sensitivity in those months. Management indicated that it expected
savings from the Cost Management Initiative to exceed plan and, coupled with
warmer than normal weather in July, help to offset the effect of the lower
wholesale prices. Management stated that a number of potentially offsetting
factors will affect 2003 earnings:

     o    wholesale energy price forecasts which are lower than previous
          projections





     o    potential increases in pension costs due to equity market performance,

     o    the impact of implementing FAS 143, which is currently being evaluated

     o    the release of a portion of the energy option contract with Edison
          Mission Energy which will affect 2003 earnings.

Management indicated that the Enterprises business segment is expected to break
even on an operating basis in the second half of 2002, exclusive of any gains or
losses which could be incurred if businesses or investments are sold.

Management also discussed ComEd's Provider of Last Resort proposal recently
filed with the Illinois Commerce Commission. ComEd is seeking permission to
limit the availability of its bundled fixed rate for electricity to 350
customers representing 2,500 MW's of load, of which customers representing
approximately 1,600 MW's of load are currently obtaining service from
Alternative Retail Electric Suppliers.
