If  the filing person has previously filed a statement on Schedule 13G to report

schedule  because  of  Section 240.13d-1(e), 240.13d-1(f) or 240.13d-1(g), check
the  following  box  /  /.

NOTE:  Schedules  filed in paper format shall include a signed original and five
copies of the schedule, including all exhibits. See Rule 13d-7 for other parties
to  whom  copies  are  to  be  sent.

*The  remainder  of this cover page shall be filled out for a reporting person's
initial filing on this form with respect to the subject class of securities, and
for  any  subsequent  amendment  containing  information  which  would  alter
disclosures  provided  in  a  prior  cover  page.

The information required on the remainder of this cover page shall not be deemed
to  be  "filed"  for the purpose of Section 18 of the Securities Exchange Act of
1934  ("Act") or otherwise subject to the liabilities of that section of the Act
but  shall  be  subject  to  all  other  provisions of the Act (however, see the
Notes).



                                  SCHEDULE 13D

Item 1. Security and Issuer

     The  Schedule  13D  filed  with  the  Securities and Exchange Commission on
October  8,  2010  by the Reporting Persons (the "Schedule 13D") with respect to
the  shares  of  Common  Stock, par value $0.01 (the "Shares"), issued by Dynegy
Inc.  (the "Issuer") and as amended by Amendment Number One and Amendment Number
Two,  is  hereby further amended to furnish the additional information set forth
herein.  All  capitalized terms contained herein but not otherwise defined shall
have  the  meanings  ascribed  to  such  terms  in  the  Schedule  13D.

Item 4. Purpose of Transaction.

     Item 4 of the Schedule 13D is amended by adding the following:

     The  Reporting  Persons  are preparing to file an application under Section
203  of  the  Federal  Power Act to obtain any approval deemed to be required to
acquire  additional shares of the Issuer's stock which would cause the Reporting
Persons aggregate ownership to exceed 10% of the Issuer's outstanding Shares, in
the  open  market  or  otherwise, including through the exercise of call options
currently  owned  by  the  Reporting  Persons, as  well as call options that the
Reporting  Persons  may  continue  to  acquire.

     The  Reporting  Persons  continue  to  believe the Dynegy/Blackstone merger
severely  undervalues  the Issuer and that the merger consideration of $4.50 per
share  is  inadequate.  In this regard we note the November 15, 2010 report from
J.P.Morgan  which  states, among other things, that J.P.Morgan is "introducing a
December  2011  price target of $7, up from our prior December 2010 price target
of  $5".

     In addition to demanding appraisal rights under Delaware law, the Reporting
Persons  intend  to  investigate  any potential voting irregularities. Since the
record  date  for the special meeting, a tremendous amount of the Issuer's stock
has  traded  hands. This high volume of trading activity has resulted in a large
number  of  record date holders who continue to have voting power over the stock
with  respect  to  the  merger,  but no longer have any economic interest in the
stock. In light of these significant changes in shareholders we believe that the
record  date  for  voting  on the transaction should be changed. Further, if the
record  date  is  not  changed and there is voting in the transaction by persons
that have no economic interest in the transaction and the merger is approved, we
intend  to  diligently  investigate  and  challenge  by  all  legal  means,  any
improprieties  in  those  votes.  Given  that  the  current trading price of the
Issuer's  stock  is above the $4.50 merger price, the Reporting Persons would be
suspicious  if the proposed transaction is approved, particularly if those votes
are  provided  by  persons  with  no  economic  interest  in  the  transaction.



                                   SIGNATURE

     After  reasonable  inquiry  and  to  the  best  of  each of the undersigned
knowledge and belief, each of the undersigned certifies that the information set
forth  in  this  statement  is  true,  complete  and  correct.
