DISCLAIMER
FORWARD-LOOKING STATEMENTS; STATEMENT OF SENECA CAPITAL BELIEFS; FORECASTS
This
presentation
contains
statements,
including
Seneca
Capital’s
beliefs
as
to
valuation,
which
are
forward
looking
statements
about
future
events
and
sets
forth
a
presentation
of
our
beliefs.
The
forward-looking
statements
are
not
guarantees
of
future
performance,
and
we
caution
you
not
to
rely
unduly
on
them.
You
should
be
aware
that
any
forward-
looking statements are based on certain assumptions and subject to risks and uncertainties that exist in the business
environment
that
could
render
actual
outcomes
and
results
that
are
materially
different.
We
have
based
many
of
these
forward-looking statements on our beliefs, expectations and assumptions about future events that may prove to be
inaccurate. While we consider these beliefs, expectations and assumptions to be reasonable, they are inherently subject
to significant business, economic, competitive, regulatory and other risks, contingencies and uncertainties, most of which
are
difficult
to
anticipate
and
many
of
which
are
beyond
our
control.
We
caution
you
that
the
forward-looking
statements
are inherently uncertain and necessarily involve risks that may affect Dynegy Inc.’s (“Dynegy”) business prospects and
performance,
causing
actual
results
to
differ
from
those
discussed
or
presented
in
this
presentation.
Without
limiting
the
generality of the foregoing, Seneca Capital’s beliefs as to future value are based on a variety of assumptions as to the
future that Seneca Capital believes constitute a reasonable, potential valuation scenario that could develop within the next
several years for Dynegy but which are nonetheless subject to risks and uncertainties that exist in the business
environment that could render actual outcomes and results materially different than anticipated.  Seneca Capital’s beliefs
as to current value are based on a variety of assumptions, including as to the future, that Seneca Capital believes
constitute reasonable assumptions but which are nonetheless subject to risks and uncertainties that exist in the business
environment that could render actual outcomes and results that are materially different.
THIRD-PARTY INFORMATION
This presentation is based on, and contains references to, third-party sources of information.  Unless otherwise provided,
no such third party has (a) participated in the preparation of this presentation, (b) other than as to Ventyx and the “Big 4

Dynegy’s capital structure provides very significant flexibility, with limited
secured debt and ample liquidity options. Unsecured debt has minimal
covenant protections:
No limitation on asset sales
No limitation on restricted payments
No limitation on debt or lien incurrence
No change of control provisions
Facing this flexibility and lack of protections, Dynegy’s unsecured debt
trades in the market at a substantial discount to its face value:

“Given forward dark spreads, we expect that up to 10GW of older/inefficient coal capacity should be retired before the '14/'15 delivery year, even
without accounting for EPA-driven retirements”
-

“We

“We assume coal plant retirements from upcoming EPA rules; CATR and HAPS MACT will be phased in over a 3-year time frame starting in 2015,
with a 15% effect in the May 2011 auction, a 50% effect in the May 2012 auction, and a 100% effect in the May 2013 auction.”

At
MISO,
we
primarily
discussed the likelihood and timeframe for implementation of a formal capacity auction. While vertically integrated regulated utilities clearly remain
relatively averse to the idea, MISO’s
initiative to develop a capacity auction stems from recent deliverability requirements demanded by FERC. As a
consequence,
MISO
has
indicated
to
FERC
that
it
intends
to
make
a
formal

MARKET PARTICIPANTS HAVE
BEGUN TO TAKE NOTICE
“If shareholders reject the BX revised offer, we believe a newly composed board and new management will likely take a
rational, long-term and creative approach to breaking up the company (potentially taking several years) and realize a
value closer to our $9 per share break-apart value.”
-
Charles Fishman, Pritchard Capital Partners, 11/17/10

“Icahn’s recent proposal to refinance DYN’s credit facilities under amended terms should assuage concerns over the
liquidity impact of asset sales/maintenance covenants. Seneca also recently proposed an additional four new board
members,
all
of
whom
have
highly
relevant
backgrounds,
including
a

executive…
We
have
incorporated
DYN’s latest disclosures into our projections, adjusting our EBITDA outlook and increasing our cash flow burn through
’15 to $2.3 Bn. In contrast, DYN’s sizeable operational and financial leverage could push equity value to $12/sh on a
power recovery and debt restructuring to mrkt value.”
-
Julien Dumoulin-Smith, UBS 11/16/10
“I believe  that,  even  at  $5.00  per share, the proposed Blackstone acquisition  undervalues Dynegy.  Today's $.50 per

increase,
coming
only
one
day
after
Blackstone
stated
that
the
$4.50
price
is
‘a

reassures
my
belief that the Dynegy/Blackstone transaction leaves too much shareholder value on the table for Blackstone.  I have also
considered that in a November 15, 2010 report JP Morgan stated that it is ‘introducing a December 2011 price target of
$7, up from our prior December price target of $5.00.’”

EPA CLEAN AIR RULES CAN
CHANGE MARKET DYNAMICS
Upcoming EPA rules may force coal generators to either invest in
expensive control technologies or shut down
Stringent Maximum Achievable Control Technology (MACT) Rules
could require compliance as early as 2014
Environmental controls can be expensive and unlikely for many plants if
the current power price environment persists
(1)
Pursuant to the Midwest Consent Decree, Dynegy will have spent $730
mm (out of a total of $960 mm) of environmental capital expenditures
for the Midwest fleet by the end of 2010 and will have substantially
completed its environmental capital expenditure program by 2013.

EPA RULES: HAZARDOUS AIR
POLLUTANT HAPS/MACT
The Clean Air Act requires the EPA to develop an emission control program for
hazardous pollutants, including mercury and acid gases
The EPA is mandated pursuant to consent decree to draft a proposed Maximum
Achievable Control Technology (HAPS/MACT) rule as soon as March 16, 2011
and to finalize it as soon as November 16, 2011
HAPS/MACT rule will apply to all existing and future coal and oil fired capacity
HAPS/MACT requires achieving emissions levels as good as the average of the
top 12% of existing representative sources
Credit Suisse estimates that for mercury emissions, this could require a 90% removal
rate
Affected plants would have 3 years to comply (i.e., 2014 or 2015), assuming no
case by case waivers or an exemption granted by the President
In
a
more
moderate
scenario,
the
EPA
could
propose
different
sets
of
standards
based on sub-categories, such as:
Size
Boiler pressure / temperature
Coal mix
No trading between plants
22


CREDIT SUISSE MID-CASE FOR
COAL PLANT RETIRMENTS
According to Credit Suisse, 66% of the coal capacity in the US have NOT installed (or
announced
plans
to
install)
both
scrubbers
and
SCRs
and
30%
have
no
environmental
controls at all
Smaller coal plants are less likely to invest in environmental controls as the capital cost is
significantly
higher
on
a
$

kw
basis.
More
than
50
GW
of
small
coal
plants

ACCOUNTING FIRM COST
STUDY
An Accounting Firm study analyzed Dynegy’s public data to determine a baseline level of costs, for
which they utilized Dynegy’s LTM financial results as of Sept. 30, 2010
O&M Costs
SG&A Costs
Cost of sales / fuel procurement
Analyzed public disclosures of selected relevant public comparable companies to determine industry
benchmarks for each cost category
GenOn, NRG Energy, Calpine, Constellation, AES and Public Service Enterprise Group
Compared Dynegy results to comparable company benchmarks in order to determine where cost
savings
would
be
possible
within
Dynegy
relative
to
its
baseline
cost
level
in
a
base
case
and
in
a
stretch case
Reviewed financial forecasts from Dynegy’s preliminary proxy statement (January 10, 2011) to
determine cost levels assumed by management, including cost savings plans already announced and
being implemented by management
Used gross margin less Adjusted EBITDA as a proxy for SG&A + O&M
costs
Compared baseline level of costs and total savings potential to 2012-2015 forecast period and 2013-
2015 forecast period costs to determine incremental savings potential for Dynegy for 2011+
$16 mm of potential incremental savings in base case
$103 mm of potential incremental savings in stretch case

VENTYX BIOGRAPHY
Ventyx is a business solutions provider offering software, data and advisory services to energy,
utility, communications, and other asset-intensive commercial industries.  Ventyx was formed in
2007 by the merger of MDSI and Indus International and the acquisition of Global Energy
Decisions and New Energy Associates during that same year.  Each
of these companies traces
their roots to the 1970’s and have been providing clients in the energy sector with energy
planning, decision support, energy trading and operations solutions.  In 2010 Ventyx was
purchased by ABB, a global leader in power and automation technologies.
The Ventyx Advisory Services Practice, which performed part of the analysis in this presentation,
traces its roots to the legacy Global Energy Decisions and New Energy Associates companies. 
The keystone product of the Ventyx Advisors Practice is the Ventyx Reference Case which is a
semi-annual forecast of North American power and fuel markets.  The Ventyx reference case is
utilized by utilities, power generators, investment bankers and market regulators as an
independent view of the current and expected state of power and fuel markets.  Over the lifetime
of this product offering the Ventyx reference case has become widely recognized with a large
subscriber base.

Comparator Analysis of Dynegy
January 2011
ADVISORY
DRAFT
1


DRAFT
Project Delta
Our findings suggest that further cost reduction and operational
efficiency may be possible at Dynegy
Key findings
Supporting evidence
Observations
The current financial
performance of Dynegy
places it at the median of
its peer group
For the 12 months ending September 2010, Dynegy has
reported an EBITDA margin of 23% versus a peer group
median of 23%.  For the comparator group chosen, the
range was between 18% and 32%
Given the limited amount of time and access to information, it is
difficult to assess Dynegy’s potential to achieve upper quartile
performance.  Additional investigation and diligence is required
Additional cost savings
and operational
efficiencies
have
been
announced and are
expected to be delivered
between now and 2013
In August 2009, a multi-year cost reduction program was
announced that was expected to deliver cumulative
savings of $400m to $450m between 2010 and 2013
the identified savings include $70m to $85m of
operating costs including an annualized $30m to $40m
of O&M and $40m to $45m of G&A
an
additional
$25m
to
$30m
of
capex
avoidance
was
also included in the announcement
As part of the proxy filing in December 2010, an
incremental $50m of savings was identified through
operational efficiencies and G&A reduction
To reach the cumulative $400m to $450m target, most of the
projected run-rate savings would have to be in-place in 2010
There appears to be a concerted effort to reduce G&A expense as
evidenced by the 10% decline, on average, per year since 2007
Updates to investors have reinforced that the program is ‘on-track’
but have not provided additional details
It is unclear if the incremental savings in the proxy filing is based on
pushing the current initiatives further or if new ideas and initiatives
have been developed
The current savings program has not been evaluated for delivery risk
It is possible that a
further $16m to $103m of
cost
savings
and
operational
improvements could be
possible, however further
validation is required
The current cost savings do not specifically mention
opportunities in the cost of sales line, which may include
transportation and distribution opportunities
When compared to historical cost levels and comparator
organizations, further upside may be possible in the
O&M and G&A lines, beyond what has already been
included in the business plan forecasts
Given the limited amount of time and access to information, it is
difficult to ascertain how much further operational improvement may
be possible in this business and further validation and diligence is
required
The largest component of the incremental savings identified is in the
O&M line.  The savings may not be entirely possible given the plant
upgrades and new emissions equipment
No
consideration
has
been
given
to
timing
or
implementation
cost
at
this time
The asset efficiency of
the organization lags the
peer group and should be
investigated further to
understand the drivers
and assess what upside
may be possible
Dynegy’s asset efficiency (EBITDA / Assets) is at 5%
and currently 4th quartile for the peer group.  For the
comparator group chosen, the range was between 5%
and 14%
Given the limited amount of time and access to information, it was
not possible to identify the specific causes for this performance.
Further investigation is required

Project Delta
We have identified an incremental $16m to $103m of potential savings,
above and beyond what may be included in the current forecasts
Methodology and Assumptions
The total potential for each of the P&L lines was determined using the 12 month period ending September 2010 as the baseline. 
Costs by type were compared with historic levels and against comparator organizations
The level of planned operating expense (O&M and G&A) going forward was estimated using the difference between gross margin
and adjusted EBITDA from the proxy filing dated 10 January 2011
(1)
The total savings potential was then compared to the published forecasts (10 January 2011 proxy filing) to understand if additional
opportunity exits, above and beyond what is included in the current business plans
Notes:
(1)  Adjusted EBITDA includes interest income and other adjustments related to mark-to-market changes, and
therefore may not be an accurate representation of the planned O&M and G&A of the business going forward

DRAFT
Project Delta
We have developed a set of hypotheses that could be refined and
tested through our structured approach
Procurement
A more strategic approach to direct and indirect procurement, including
centralizing the procurement function across Dynegy, may reduce costs
across the organization
H1
Maintenance
and
Operations
Improvements to the maintenance and operations strategy and practices,
including
a
shift
to
more
preventative
maintenance,
and
improved
scheduling,
planning and prioritizing of work could reduce O&M costs in the organization
H2
Equipment
Effectiveness
Targeted investments and a more effective maintenance program may
improve
the
OEE
of
the
plants,
resulting
in
improved
utilization
and
availability,
leading to reduced cost and improved profit
H3
Capital
Expenditures
A more rigorous approach to capex
approval and project governance could   
reduce capex
levels
H4
Inventory /
Spare Parts
A
better
controlled
procurement
process
and
a
well
defined
spare
parts
strategy could reduce operating expense and release working capital through
spare parts reduction
H5
Support
Functions
Driving efficiency across the support functions through centralization,
outsourcing
and
the
use
of
‘self-service’
models
could
reduce
G&A
costs
in
the business

Summary of previously announced cost saving programs
Current cost improvement
initiatives
Additional detail
Observations
In July 2009, Dynegy reported
that a cumulative $400m to
$450m of operating
efficiencies could be achieved  
between 2010 and 2013 with
annual run-rates  between
$95m and $110m
(1)
Dynegy announced an extensive, multi-year program to
eliminate costs throughout the company. Cumulative
savings, relative to Dynegy’s original plan, are expected
to be $400m to $450m over a four-year period beginning
in 2010
Annual savings are expected to be generated through
the following means:
reduced capital expenditures, with a targeted range of
$25m to $30m in savings per year;
reduced operational expenditures, with a targeted range
of $30m to $40m in savings per year; and
reduced general and administrative expenditures, with a
targeted range of $40m to $45m in savings per year
It does not appear that there have been additional
updates with respect to the timing, areas of focus
or progress towards targets aside from the
comments in the quarterly investor updates
indicating that the program is on-track
If the savings are based on a 2009 baseline, this 
represents an EBITDA improvement of
approximately 3 points from 23% to 26% of sales
approximately 25% reduction in SG&A expense
approximately 7% reduction in O&M expense
Reduction in capex
is grouped in with the operating
cost improvements, however direct P&L impact is
not expected
As part of the proxy
statement released on
January 10, 2011 from
Dynegy to its shareholders,
an additional $50m of annual
cost savings may be possible,
beginning in 2011 and
incremental to the previously
announced targets
(2)
Implementation of a cost savings program focused on
reducing general, administrative and operational  
expenses generates approximately $50m in annual cost
savings beginning in 2011. 
Implementation has not yet commenced and would be
incremental to the cost savings targets included in the
Company’s previously announced 2010-2013 cost
savings program
No further detail is provided as to where these cost
savings will come from or the cost and risk
associated with achieving this level of savings

DRAFT
Methodology and Assumptions
To
estimate
the
planned
level
of
operating
expense
(O&M
and
G&A)
going
forward,
the
projected gross margin of the business was compared to the projected Adjusted
EBITDA using the forecasts found in the 10 January 2011 proxy filing
it is important to note that there is a difference between the $702m of estimated
operating expense found using this method for 2010E and the LTM baseline
($631m) used to calculate the potential savings of $71m (10%).  This could be due
to the impacts of interest income, mark-to-market changes or changes in the
operating cost base of the business and should be investigated further
Once the expected level of operating expense was determined for each of the forecast
periods, it was assumed that 2013 and beyond could be used to understand the
planned level of operating expense once all of the current cost reduction programs
were completed
this analysis will only identify the net forecast change in estimated operating
expense which will include both increases due to increasing costs of goods and
services and cost reduction efforts that may be planned and delivered as part of the
announced programs and further efforts by management

Analysis of proxy filing
Notes:
(1)  Adjusted EBITDA includes interest income and other adjustments related to mark-to-market changes, and
therefore may not be an accurate representation of the planned O&M and G&A of the business going forward
Source:
Preliminary
proxy statements relating to merger or acquisition, DPREM 14A, 10 January 2011 page 59 ; Analysis
Recommended next steps
Validate the actual planned levels of O&M and G&A in
the business plan going forward
and compare these
to the actual 2010 results to determine what level of
cost reduction may be planned
Review the assumptions and operating initiatives that
were used to develop the plans to understand the
robustness of those plans and assumptions
Understand and model the impact of off-setting items
including normalizing for changes in revenue, inflation,
changes in the asset base or other known items that
could impact the required level of operating expense
going forward
