Cautionary Statements Regarding
Forward-Looking Information
2
Except for the historical information contained herein, certain of the matters discussed in this communication constitute “forward-
looking statements” within the meaning of the Securities Act of 1933 and the Securities Exchange Act of 1934, both as amended by
the Private Securities Litigation Reform Act of 1995. Words such as “may,” “will,” “anticipate,” “estimate,” “expect,” “project,” “intend,”
“plan,” “believe,” “target,” “forecast,” and words and terms of similar substance used in connection with any discussion of future plans,
actions, or events identify forward-looking statements. These forward-looking statements include, but are not limited to, statements
regarding benefits of the proposed merger of Exelon Corporation (Exelon) and Constellation Energy Group, Inc. (Constellation),
integration plans and expected synergies, the expected timing of completion of the transaction, anticipated future financial and
operating performance and results, including estimates for growth. These statements are based on the current expectations of
management of Exelon and Constellation, as applicable. There are a number of risks and uncertainties that could cause actual results
to differ materially from the forward-looking statements included in this communication regarding the proposed merger. For example,
(1) the companies may be unable to obtain regulatory approvals required for the merger, or required regulatory approvals may delay
the merger or result in the imposition of conditions that could have a material adverse effect on the combined company or cause the
companies to abandon the merger; (2) conditions to the closing of the merger may not be satisfied; (3) an unsolicited offer of another
company to acquire assets or capital stock of Exelon or Constellation could interfere with the merger; (4) problems may arise in
successfully integrating the businesses of the companies, which may result in the combined company not operating as effectively and
efficiently as expected; (5) the combined company may be unable to achieve cost-cutting synergies or it may take longer than
expected to achieve those synergies; (6) the merger may involve unexpected costs, unexpected liabilities or unexpected delays, or the
effects of purchase accounting may be different from the companies’ expectations; (7) the credit ratings of the combined company or
its subsidiaries may be different from what the companies expect; (8) the businesses of the companies may suffer as a result of
uncertainty surrounding the merger; (9) the companies may not realize the values expected to be obtained for properties expected or
required to be divested; (10) the industry may be subject to future regulatory or legislative actions that could adversely affect the
companies; and (11) the companies may be adversely affected by other economic, business, and/or competitive factors. Other
unknown or unpredictable factors could also have material adverse effects on future results, performance or achievements of Exelon,
Constellation or the combined company.

Exelon Generation Hedging Program
As a consequence of being ahead of a ratable pace in
2009 and 2010 in the PJM portfolio we were able to
capture higher market prices and be selective in 2011 by
holding off on sales when prices were low.

Over the Past Three Years
2012 South & West Hedging

Important Information
The following slides are intended to provide additional information regarding the hedging
program at Exelon Generation and to serve as an aid for the purposes of modeling Exelon
Generation’s gross margin (operating revenues less purchased power and fuel expense). The
information on the following slides is not intended to represent earnings guidance or a forecast of
future events.  In fact, many of the factors that ultimately will determine Exelon Generation’s
actual gross margin are based upon highly variable market factors outside of our control.  The
information on the following slides is as of December 31, 2011.  We update this information on a
quarterly basis.
Certain information on the following slides is based upon an internal simulation model that
incorporates assumptions regarding future market conditions, including power and commodity
prices, heat rates, and demand conditions, in addition to operating performance and dispatch
characteristics of our generating fleet.  Our simulation model and the assumptions therein are
subject to change.  For example, actual market conditions and the dispatch profile of our
generation fleet in future periods will likely differ – and may differ significantly – from the
assumptions underlying the simulation results included in the slides.  In addition, the forward-
looking information included in the following slides will likely change over time due to continued
refinement of our simulation model and changes in our views on future market conditions.

Portfolio Management Objective
Align Hedging Activities with Financial Commitments
Power Team utilizes several product types
and channels to market
Wholesale and retail sales
Block products
Load-following products
and load auctions
Put/call options
Exelon’s hedging program is designed to
protect the long-term value of our
generating fleet and maintain an
investment-grade balance sheet
Hedge enough commodity risk to meet future cash
requirements if prices drop
Consider:  financing policy (credit rating objectives,
capital structure, liquidity); spending (capital and
O&M); shareholder value return policy
Consider market, credit, operating risk
Approach to managing volatility
Increase hedging as delivery approaches
Have enough supply to meet peak load
Purchase fossil fuels as power is sold
Choose hedging products based on generation
portfolio
sell what we own
Heat rate options

Exelon Generation Open Gross Margin and
Reference Prices
(1)
Based on December 31, 2011 market conditions. 
(2)
Gross margin is defined as operating revenues less fuel expense and purchased power expense, excluding the impact of decommissioning and other incidental
revenues. Open gross margin is estimated based upon an internal model that is developed by dispatching our expected generation to current market power and fossil
fuel prices. Open gross margin assumes there is no hedging in place other than fixed assumptions for capacity cleared in the RPM auctions and uranium costs for
nuclear power plants. Open gross margin contains assumptions for other gross margin line items such as various ISO bill and ancillary revenues and costs and PPA
capacity revenues and payments.The estimation of open gross margin incorporates management discretion and modeling assumptions that are subject to change.

Generation Profile
(1)
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 at Exelon-operated nuclear plants and Salem.  Expected generation assumes
capacity factors of 93.5%, 93.3% and 93.4% in 2012, 2013 and 2014 at Exelon-operated nuclear plants. These estimates of expected generation in 2012, 2013 and 2014 do not
represent guidance or a forecast of future results as Exelon has not completed its planning or optimization processes for those years.
(2)
Percent of expected generation hedged is the amount of equivalent sales divided by the expected generation. Includes all hedging products, such as wholesale and retail sales of
power, options, and swaps. Uses expected value on options. Reflects decision to permanently retire Cromby Station and Eddystone Units 1&2 as of May 31, 2011. 
(3)
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.

Exelon Generation Gross Margin Sensitivities
(with Existing Hedges)
(1)
Based on December 31, 2011 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.

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 2012 , 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 December 31, 2011.

Appendix


2011 results were achieved in a very
challenging market environment due to
effectiveness of asset allocations and
hedging strategy
Decreased equity investments and
increased investment in fixed income
securities and alternative investments
The liability hedge has offset more than 
50% of the pension liability increase
caused by lower interest rates
Pension plans are 83% funded as of
December 31, 2011
Pension Funds Performance
Exelon’s pension investment strategy has effectively dampened the volatility
of plan assets and plan funded status
