Position
1. Exelon expects that NRG’s planned equity selldown

approximately 35%, or   936 MW, and possibly even less
“We are impressed with Exelon's optimistic plans to add up to 1,500 MW from nuclear uprates
over the next eight
years…The returns on these investments should be very attractive, as the company does not anticipate a higher run-
rate of O&M expenses (i.e., O&M/MWh
should decrease).”

Carbon Legislation is Gaining Momentum and
Will Benefit the Combined Company
•
Waxman-Markey legislation provides allocations to merchant coal units only if they actually run in any given year –
with this allocation mechanism, merchant coal plants will dispatch more than is economically efficient and fewer
merchant coal plants will retire
•
If merchant coal allocations are granted in a manner that does not change dispatch and retirement incentives,
Exelon’s EBITDA would increase by about $1.5 billion and NRG’s EBITDA would increase by about $150M in Year 1
•
While Exelon has supported merchant coal allocations as part of an overall industry compromise, if no allocations
are granted, Exelon’s EBITDA would increase by $1.5 billion and NRG’s EBITDA will decrease by $150M in Year 1
Note: Dollar values reflect illustrative results based on potential outcomes of climate legislation and should not be interpreted as a forecast for future periods.       
The carbon benefit to be realized by Exelon’s nuclear fleet will significantly
exceed the carbon costs faced by NRG’s coal-dominated generation fleet

NRG Shareholders can secure the best transaction possible by taking the following actions:
This approach will allow NRG shareholders to share in the significant value to be
generated from creating the largest, most diversified
power company in the U.S.
33
This will not
result
in Exelon’s slate
constituting a
majority of the
NRG Board
•
NRG’s Board has been entrenched in its steadfast opposition to a transaction
with Exelon by:
-
Supporting an entrenched CEO and Senior Management who have sought to
obstruct Exelon’s attempts to obtain regulatory approvals for the
transaction
-
Consistently ignoring the spoken will of a majority of NRG’s shareholders
and refusing to negotiate with Exelon or allow due diligence
•
We are committed to this transaction but will continue our efforts only as long
as we have shareholder support.  The election of only four new directors would
raise a significant question about the level of that support
Voting For Only Four Directors Will Reduce the Likelihood of a Value-Enhancing Transaction
It’s Time to Capture This Value

The negative impact to

Exelon has the liquidity, market access and financial flexibility to manage risk

Risks Inherent In A Non-investment Grade
Balance Sheet
Though currently re-opened, the non-investment grade market has closed on several occasions in recent

RPM Capacity Auctions in PJM
The results of the recent RPM capacity auction are not anticipated to reflect a new
“norm”
due to an anticipated market response to low clearing prices and rule changes
for demand response bidding
•
The RTO clearing price for 2012/2013 was $16.46 MW-day.  The clearing price
for MAAC and Eastern MAAC resources was $133.37 MW-day and $139.73
MW-day respectively. 
-
Exelon offered 12,200 MWs
of
capacity in the RTO region; 1,500 MWs
in the MAAC
region; and 9,600 MWs
of
capacity in Eastern MAAC region
•
A market response to the low clearing prices in the RTO region is anticipated
-
Modified resource bidding behavior
-
Retirement of costly and less efficient generation
-
Cancellation of new generation projects
-
Less Cleared Demand Response (DR)
•
The RPM capacity auction prices for 2012/2013 are the result of increased
generation supply and demand response resources, decreased load PJM wide,
and locational
reliability requirements
•
The 2012/2013 capacity auction was the first time in which Interruptible Load
Resources (ILR) were required to offer into RPM as a capacity resource
-
The
PJM
tariff
was
interpreted
to
require
existing
ILR
Resources
to
bid
at
$0
•
On June 8, 2009, PJM and its stakeholders began considering changes that
would eliminate offer caps on DR
-
Tariff changes could result in future auctions that better reflect the true market
value of capacity (i.e. the value to end use customers who sell firm power rights)

NRG Underestimates the Risks of Being a First Mover
STP 3&4 Is Subject To Project Execution And Cost
Escalation Risks That NRG Shareholders Cannot Ignore
•
U.S. Supply chain and labor force must be re-established
•
Japanese modular construction practices have not been
applied in the U.S.
•
NRG has not announced completion of construction
contract
•
U.S. labor productivity vs. Japanese is unknown
•
Construction proximity to an operating nuclear plant poses
significant risk to construction execution, schedule, and cost
•
Owner’s costs and site development risks are material,
despite the brownfield
site

Scale and Complexity of Nuclear New Build
Introduces a Unique Set of Challenges for NRG
44
New nuclear build is a high risk proposition for NRG and represents a substantial
portion of the company’s market cap
•
Even with financing support by the U.S. and Japanese governments, NRG is
placing a significant portion of the company’s market cap at risk
•
Exelon’s size and investment grade balance sheet significantly lessens the impact
of this mega-project on the company’s operating and financial risk profile

New build equity financing percentages are presented for various levels of total nominal project costs per kW, assuming 80% debt funding and 
market capitalization as of 6/26/09. The equity financing percentages reflect NINA ownership of STP units 3 and 4 at 40%, and NRG ownership of 
NINA at 88%. 
2.
Estimate of the total nominal project cost per kW based on the midpoint of the NRG price range for the nominal EPC and owners’ cost from 
NRG’s 6/4/09 presentation at Macquarie Global Infrastructure Conference, plus estimated interest during construction, initial fuel load costs, 
guaranteed loan fees and debt service reserve.

NRG Is Overvaluing Reliant Retail’s Financial
Impact
Valuation Considerations
Even when assuming a $250 million run rate EBITDA for Reliant Retail, the
financial impact to NRG is less than $1.00 per share
•
Exelon fully supports the retail business model, and the Reliant
acquisition appears value-accretive
•
However,
the
suggestion
that
over
$1
billion
in
equity
value
(or
~$4.50
per
share)
has
been
created
is
an overstatement
•
Valuation of 4-6x EBITDA is not achievable
–
NRG paid 1.9x to 2.6x
EBITDA in an auction
–
Public markets have not imputed attractive
multiples
to retail businesses in the past
•
No allocation of debt
in NRG’s valuation either in the
form of collateral or increased working capital
•
NRG seems to ignore the higher level of risk
for retail;
implies higher cost of capital
Potential Price Per Share Impact ($ M)
•
$250 million run rate EBITDA appears aggressive
–
Gross margins
($670 M) assume steady mass market
and Commercial & Industrial margins which have been
volatile
–
Aggressive pricing from large competitors
(e.g.,
Centrica, FPL, CEG) will
likely compress margins
–
Requires strong execution
across
key disciplines (e.g.,
risk management, customer service)

Under the new administration, we anticipate there will be more stringent environmental rules and
regulations,
including
NOX
and
SO2
and
particulate
reductions
under
a
revised
Clean
Air
Interstate
Rule
(CAIR), an aggressive EPA/DOJ New Source Review enforcement initiative
•
These regulations
may
result
in
significant

costs
for
NRG’s

assets
•
These regulations will have minimal impact on Exelon’s compliance costs given our nuclear portfolio

In its 3/31/09 Form 10-Q, NRG states that it has prepared an environmental capital expenditure plan for numerous pending
regulations but does not disclose the amount of the planned expenditures.

Forecasted amounts shown above are included in transaction analysis.

NRG claims
that its hedge program insulates it from the current commodity
down-cycle…
looking
closer:
•
NRG has sold about 2/3 of its baseload
energy forward for 2011, but at much lower prices
than for 2009 sales
•
As
NRG’s
above-market
hedges
roll
off,
we
estimate
that
NRG’s
baseload
energy
revenues
could decline by ~$700 million based on current market prices between 2009 and 2011
At Current Forward Prices, ~$700 Million in
