Overview of Exelon Corporation


The Exchange Offer
On November 12   , Exelon launched an exchange offer
for all of the outstanding shares of NRG
Filed Form S-4 with the SEC
Fixed exchange ratio of 0.485 Exelon share for each NRG
common share
Represents a 37% premium to the October 17    NRG closing
price
Initial exchange offer period expires January 6, 2009

Financing Is Not an Obstacle
Exelon believes it can secure committed financing for the
transaction at the appropriate time
We believe a negotiated combination can be structured in a
way to reduce refinancing requirements to $4B or less
We believe that the contemplated structure would not trigger the
change of control provision for NRG’s $4.7B of Senior Notes, and would
substantially improve credit metrics for those bondholders
Exelon’s relationships with many of NRG’s banks should facilitate
arrangements for new credit facilities once current conflicts are
eliminated
We believe that the NRG direct lien program for power
marketing could be left in place
6
Reflecting our confidence that we can obtain secure
committed financing at the appropriate time, the transaction
will not be subject to a financing condition


Full and generous price –
upfront premium of 37%
Opportunity to participate in the future growth of the
largest and most diversified US power company, with a
substantially improved credit profile
Requisite scope, scale and financial strength
Stronger credit metrics and investment grade balance sheet
Best-in-class nuclear and fossil operations
Low-cost generator, operating in the most attractive markets
Exelon 2020 principles will be adapted to the combined fleet
Potential for substantial synergies
Manageable regulatory hurdles to close

Exelon More Than Meets the “Five
Imperatives”
Outlined by NRG on May 28, 2008
1.
2.
3.
4.
5.
NRG’s Stated Imperatives
MUST
accumulate generation at competitive cost
This transaction accomplishes in one step what several transactions
might have accomplished for NRG in these regards.  Given the
current difficulty in accessing capital markets, it is unclear whether
NRG would have the ability to meet this objective without Exelon.
Exelon provides NRG stakeholders with broad trading expertise and
sound power marketing and risk management practices.  Exelon’s
significant experience in markets with locational prices is
particularly relevant since ERCOT is moving to a PJM-type structure.
Exelon’s breadth of operations and depth of service allows
significant access to customers, retail providers, and other sales
channels.
NRG stakeholders become part of the most diversified and
competitive generation portfolio operating in 12 different states
and 6 different regional transmission organizations.
Deal expected to provide NRG stakeholders with significant value
and upside and a share of the largest unregulated generation fleet
in the United States.
MUST
be geographically diversified in multiple markets
MUST
develop and expand our route to market through
contracting with retail load providers, trading, direct sales, etc
MUST
have sophisticated ability to trade, procure, hedge, and
originate for electricity and input fuels
MUST
develop depth and breadth in key markets, particularly
across fuel types, transmission constraints and merit order
Exelon Combination More
than Meets These Imperatives
