Position our regional portfolios within our Bull/Bear framework to best take advantage of various market anomalies

Further utilize cross-commodity hedges to protect against further downside in the natural gas market, while remaining

2012 3Q Earnings Release Slides

(1) Stub period calculated by excluding Jan 2012 through mid-March 2012 for Constellation only. (2) Excludes Maryland assets to be divested (3) Includes CENG Joint Venture. (4) Expected

generation represents the amount of energy estimated to be generated or purchased through owned or contracted for capacity.  Expected generation is based upon a simulated dispatch model

that makes assumptions regarding future market conditions, which are calibrated to market quotes for power, fuel, load following products, and options. Expected generation assumes 10

refueling outages in 2012 and 2013 and 11 refueling outages in 2014 and 2015 at Exelon-operated nuclear plants and Salem but excludes CENG.  Expected generation assumes capacity

factors of 92.8%, 93.5%, 93.8%, and 93.3% in 2012, 2013, 2014 and 2015 at Exelon-operated nuclear plants excluding Salem and CENG. These estimates of expected generation in 2012,

2013, 2014 and 2015 do not represent guidance or a forecast of future results as Exelon has not completed its planning or optimization processes for those years.  (5) Percent of expected

generation hedged is the amount of equivalent sales divided by expected generation.  Includes all hedging products, such as wholesale and retail sales of power, options and swaps. Uses

expected value on options. (6) Effective realized energy price is representative of an all-in hedged price, on a per MWh basis, at which expected generation has been hedged.  It is developed by

considering the energy revenues and costs associated with our hedges and by considering the fossil fuel that has been purchased to lock in margin. It excludes uranium costs and RPM

capacity revenue, but includes the mark-to-market value of capacity contracted at prices other than RPM clearing prices including our load obligations.  It can be compared with the reference

prices used to calculate open gross margin in order to determine the mark-to-market value of Exelon Generation's energy hedges. (7) Spark spreads shown for ERCOT and New England.

2012 3Q Earnings Release Slides

(1) Based on September 30, 2012 market conditions and hedged position. Gas price sensitivities are based on an assumed gas-power relationship derived from an internal model

that is updated periodically. Power prices sensitivities are derived by adjusting the power price assumption while keeping all other prices inputs constant. Due to correlation of the

various assumptions, the hedged gross margin impact calculated by aggregating individual sensitivities may not be equal to the hedged gross margin impact calculated when

correlations between the various assumptions are also considered. (2) Excludes Maryland assets to be divested. (3) Includes CENG Joint Venture (4) Sensitivities based on

commodity exposure which includes open generation and all committed transactions.

Exelon Generation Hedged Gross Margin Upside/Risk

2012 3Q Earnings Release Slides

2012 3Q Earnings Release Slides

(1) Represents an approximate range of expected gross margin, taking into account hedges in place, between the 5th and 95th percent confidence levels assuming all unhedged

supply is sold into the spot market.  Approximate gross margin ranges are based upon an internal simulation model and are subject to change based upon market inputs, future

transactions and potential modeling changes. These ranges of approximate gross margin in 2013 and 2014 do not represent earnings guidance or a forecast of future results as

Exelon has not completed its planning or optimization processes for those years. The price distributions that generate this range are calibrated to market quotes for power, fuel, load

following products, and options as of September 30, 2012 (2) Gross Margin Upside/Risk based on commodity exposure which includes open generation and all committed

Net of costs recoverable through EIMA. During the fourth quarter of 2011, ComEd received a credit of $0.04 earnings per share, net of amortization, for the allowed recovery of certain 2011

storm costs pursuant to EIMA. During the fourth quarter of 2012, ComEd anticipates recording $0.10 earnings per share to recognize the impact of the ICC’s rehearing decision issued on

October 3, 2012.

Due to the true-up mechanism in the distribution formula rate, the primary driver of year-over-year change in earnings will be due to changes in allowed ROE, rate base and capital structure.
