Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) On April 2, 2007, Dynegy Inc. (the ?Issuer?) merged into a wholly owned subsidiary (the ?Merger?) of Dynegy Acquisition, Inc., now known as Dynegy Inc. (the ?Successor?). In connection with the Merger, each share of Issuer common stock was converted into the right to receive one share of Successor common stock.
(2) These shares of phantom stock are convertible to Class A common stock on a 1-for-1 basis.
(3) Upon termination of the Reporting Person?s service as a director, the shares of phantom stock become payable, at the election of the Reporting Person, in a lump sum payment or in monthly, quarterly or annual installment payments following such termination. The shares of phantom stock are payable in cash or in shares of Class A common stock.
(4) Each share of Issuer phantom stock was converted into one share of Successor phantom stock, with the same terms and conditions applicable to the Issuer phantom stock, at the effective time of the Merger.
(5) These shares of phantom stock are deemed to be payable immediately as the Reporting Person may elect at any time to transfer the value of such shares to an alternative investment fund maintained by the Issuer under the Dynegy Inc. Deferred Compensation Plan for Certain Directors, as amended. The Successor assumed such plan in connection with the Merger.
(6) Upon termination of the Reporting Person's service as a director, the shares of phantom stock become payable in cash, at the election of the Reporting Person, in a lump sum payment or in monthly, quarterly or annual installment payments following such termination.
