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,
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 Corporation (Exelon) and Constellation Energy Group, Inc. (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. For example, (1) the companies may be unable to obtain
shareholder approvals required for the merger; (2) 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; (3) conditions
to the closing of the merger may not be satisfied; (4) an unsolicited offer of another company to acquire assets or capital
stock of Exelon or Constellation could interfere with the merger; (5) 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; (6) the combined company may be unable to achieve cost-cutting synergies or it may take longer than expected
to achieve those synergies; (7) the merger may involve unexpected costs, unexpected liabilities or unexpected delays, or
the effects of purchase accounting may be different from the companies’ expectations; (8) the credit ratings of the
combined company or its subsidiaries may be different from what the companies expect; (9) the businesses of the
companies may suffer as a result of uncertainty surrounding the merger;


Cautionary Statements Regarding
Forward-Looking Information (Continued)

(10) the companies may not realize the values expected to be obtained for properties expected or required to be divested;
(11) the industry may be subject to future regulatory or legislative actions that could adversely affect the companies; and
(12) 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 the
combined company. Discussions of some of these other important factors and assumptions are contained in Exelon’s and
Constellation’s respective filings with the Securities and Exchange Commission (SEC), and available at the SEC’s website

Factors Influencing PJM RPM Capacity Auction
(Comparison of PY 14/15 and PY 13/14 Price Drivers)
Exelon
Price Impact
Cost of Environmental Upgrades
(1)
Higher Net CONE
(2)
Higher Net ACRs for Coal Units
(3)
Import Transmission Limits and Objectives 
(muted impact on portfolio revenues due to regional diversification)
NJ CCGT Proposal / PJM Minimum Offer Price Rules
Peak Load
(4)
Demand Response Growth
2014/15 PJM Capacity Auction: Expected
Changes Since Planning Year 2013/14
Expect overall results to be similar to last year’s auction
N/A
(1)  We expect generators to reflect cost of capital expenditures into their cost based offers at the upcoming auction.
(2)  Cost of new entry (CONE) increased by 7.6% (for RTO) and 5.3% to 6.5% (within Locational Deliverability Areas (LDAs)).
(3)  Replacing 2007 net revenues with significantly lower 2010 revenues in the Net ACR (avoidable cost rate) calculations for coal generators may increase offer caps for certain
coal generators
in
the
next
auction.
However,
some
coal
units
may
not
be
affected
due
to
high
net
revenues
compared
to
avoidable
costs.
(4)  Peak load reduced by approx. 1% in RTO (excluding the impact from Duke Ohio integration).

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 March 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, operational 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
Fuel products

Our normal practice is to hedge commodity risk on a ratable basis
over the three years leading to the spot market
Carry operational length into spot market to manage forced outage and load-following
risks
By
using
the
appropriate
product
mix,
expected
generation
hedged
approaches the
mid-90s percentile as the delivery period approaches
Participation in larger procurement events, such as utility auctions, and some flexibility
in the timing of hedging may mean the hedge program is not strictly ratable from
quarter to quarter

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
12
refueling
outages
in
2011
and
10
refueling
outages
in
2012
and
2013
at
Exelon-operated
nuclear
plants
and
Salem.
Expected
generation
assumes
capacity
factors of 93.0%, 93.6% and 93.1% in 2011, 2012 and 2013 at Exelon-operated nuclear plants. These estimates of expected generation in 2012 and 2013 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 March 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 and 2013 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 March 31, 2011.
