(1)  Primarily related to cooler summer weather in 2003 as compared to 2002.

     decline in revenue.

(7)  Reflects lower interest expense, excluding the effect of the acquisition of ENE, due to

<FN>
(1)  Gain on Exelon Enterprises' sale of its 49% interest in AT&T Wireless PCS of
     Philadelphia.

(2)  Executive severance partially offset by favorable adjustments to previous
     severance estimates. A portion of the executive severance was not tax
     deductible. As a result, the after-tax impact on earnings was $0.04 per share.

(3)  Primarily related to increased market sales of electricity at higher prices by
     Generation along with reductions in capacity payments to Midwest Generation.
     Excludes the effect of the acquisition of Sithe New England (currently known as
     Exelon New England (ENE)) in November 2002.

(4)  Primarily related to cooler spring and summer weather in 2003 as compared to
     2002, partially offset by colder winter weather in 2003 as compared to 2002.

(5)  Reflects lower interest expense, excluding the effect of the acquisition of
     ENE, due to refinancing of existing debt at lower interest rates and the
     gradual retirement of ComEd's Transitional Trust Notes.

(6)  Reflects reduced operating expenses, excluding severance charges, the effect of
     the acquisition of ENE, the net loss on the sale of InfraSource, Inc.
     in the second quarter of 2003 and SFAS No. 143, primarily due to decreased
     salaries and wages at Energy Delivery, decreased nuclear refueling outages at
     Generation and the deployment of automated meter reading technology at PECO.
     These decreases were partially offset by increased pension and postretirement
     benefit expense and increased storm costs in the Energy Delivery service
     territories.

(7)  Primarily reflects the effects of write-downs of communication and
     energy-related investments at Enterprises in 2002 and higher investment income
     related to nuclear decommissioning trust funds in 2003, partially offset by an
     impairment of communication and energy-related investments of Enterprises in
     2003.

(8)  Reflects lower non-energy margins at Enterprises, primarily InfraSource, due to
     an overall decline in revenue.

(9)  Depreciation and amortization expense, excluding SFAS No. 143 and the effect of
     the acquisition of ENE in November 2002, was lower primarily due to lower
     depreciation rates and lower recoverable transition cost amortization at ComEd,
     partially offset by increased depreciation related to higher depreciable plant
     balances, reflecting Generation's plant acquisitions in 2002 and additions at
     Energy Delivery, and higher CTC amortization at PECO.

(10) Reflects the effect on net income of the acquisition of ENE in November 2002,
     excluding the impairments of EBG and Sithe Energies, Inc.

(11) Reflects the impairment of the EBG assets recorded by Generation during the
     third quarter of 2003.

(12) Impairment of the investment held by Generation in Sithe Energies, Inc.
     recorded during the first and third quarters of 2003.

(13) Reflects severance and severance related costs recorded during the third
     quarter of 2003.

(14) Reflects the reduction of certain property tax accruals at PECO and Generation
     during the third quarter of 2003.

(15) Agreement reached by ComEd and various Illinois suppliers, customers, and
     governmental parties regarding several matters affecting ComEd's rates for
     electric service during the first quarter of 2003.

(16) Reflects the net impact of an impairment of goodwill related to InfraSource,
     Inc. in the second quarter of 2003 and the loss on the sale of the electric
     construction and services, underground and telecom businesses of InfraSource
     Inc., which closed during the third quarter of 2003.

(a)  Bundled service reflects deliveries to customers taking electric service under tariffed rates, which include the
     cost of energy and the delivery cost of the transmission and distribution of the energy. PECO's tariffed rates also
     include a CTC charge.


(b)  Unbundled service reflects customers electing to receive electric generation service under the ComEd PPO option or
     from an alternative energy supplier. Revenue from customers choosing the ComEd PPO option includes an energy charge
     at market rates, transmission and distribution charge and a CTC charge. Revenue from customers choosing an
     alternative energy supplier includes a distribution charge and a CTC charge. Transmission charges received from
     alternative energy suppliers are included in wholesale and miscellaneous revenue.

(c)  On May 1, 2002, all ComEd residential customers were eligible to choose their supplier of electricity; however, as
